Sage is a powerful tool—but you don't have to take my word for it. This article will showcase a few of the things that Sage can do to enhance your work. Look at the things Sage can do, and start to think about how Sage might be useful to you.
Getting started
You don't have to install Sage to try it out! In this article, we will use the notebook interface to showcase some of the basics of Sage so that you can follow along using a public notebook server. These examples can also be run from an interactive session if you have installed Sage. Go to and sign up for a free account. You can also browse worksheets created and shared by others. The notebook interface should look like this:
Create a new worksheet by clicking on the link called New Worksheet:
Type in a name when prompted, and click Rename. The new worksheet will look like this:
Enter an expression by clicking in an input cell and typing or pasting in an expression:
Click the evaluate link or press Shift-Enter to evaluate the contents of the cell.
A new input cell will automatically open below the results of the calculation. You can also create a new input cell by clicking in the blank space just above an existing input cell.
Using Sage as a powerful calculator
Sage has all the features of a scientific calculator—and more. If you have been trying to perform mathematical calculations with a spreadsheet or the built-in calculator in your operating system, it's time to upgrade. Sage offers all the built-in functions you would expect. Here are a few examples:
If you have to make a calculation repeatedly, you can define a function and variables to make your life easier. For example, let's say that you need to calculate the Reynolds number, which is used in fluid mechanics:
When you type the code into an input cell and evaluate the cell, your screen will look like this:
Now, you can change the value of one or more variables and re-run the calculation:
Sage can also perform exact calculations with integers and rational numbers. Using the pre-defined constant pi will result in exact values from trigonometric operations. Sage will even utilize complex numbers when needed. Here are some examples:
Symbolic mathematics
Much of the difficulty of higher mathematics actually lies in the extensive algebraic manipulations that are required to obtain a result. Sage can save you many hours, and many sheets of paper, by automating some tedious tasks in mathematics. We'll start with basic calculus. For example, let's compute the derivative of the following equation:
The following code defines the equation and computes the derivative:
var('x') f(x) = (x^2 - 1) / (x^4 + 1) show(f) show(derivative(f, x))
The results will look like this:
The first line defines a symbolic variable x (Sage automatically assumes that x is always a symbolic variable, but we will define it in each example for clarity). We then defined a function as a quotient of polynomials. Taking the derivative of f(x) would normally require the use of the quotient rule, which can be very tedious to calculate. Sage computes the derivative effortlessly.
Now, we'll move on to integration, which can be one of the most daunting tasks in calculus. Let's compute the following indefinite integral symbolically:
The code to compute the integral is very simple:
f(x) = e^x * cos(x) f_int(x) = integrate(f, x) show(f_int)
The result is as follows:
To perform this integration by hand, integration by parts would have to be done twice, which could be quite time consuming. If we want to better understand the function we just defined, we can graph it with the following code:
f(x) = e^x * cos(x) plot(f, (x, -2, 8))
Sage will produce the following plot:
Sage can also compute definite integrals symbolically:
To compute a definite integral, we simply have to tell Sage the limits of integration:
This would have required the use of a substitution if computed by hand.
Have a go hero
There is actually a clever way to evaluate the integral from the previous problem without doing any calculus. If it isn't immediately apparent, plot the function f(x) from 0 to 1 and see if you recognize it. Note that the aspect ratio of the plot may not be square.
The partial fraction decomposition is another technique that Sage can do a lot faster than you. The solution to the following example covers two full pages in a calculus textbook —assuming that you don't make any mistakes in the algebra!
We'll use partial fractions again when we talk about solving ordinary differential equations symbolically.
Linear algebra
Linear algebra is one of the most fundamental tasks in numerical computing. Sage has many facilities for performing linear algebra, both numerical and symbolic. One fundamental operation is solving a system of linear equations:
Although this is a tedious problem to solve by hand, it only requires a few lines of code in Sage:
Notice that Sage provided an exact answer with integer values. When we created matrix A, the argument QQ specified that the matrix was to contain rational values. Therefore, the result contains only rational values (which all happen to be integers for this problem).

Solving an ordinary differential equation
Solving ordinary differential equations by hand can be time consuming. Although many differential equations can be handled with standard techniques such as the Laplace transform, other equations require special methods of solution. For example, let's try to solve the following equation:
It turns out that the equation we solved is known as Bessel's equation. This example illustrates that Sage knows about special functions, such as Bessel and Legendre functions. It also shows that you can use the assume function to tell Sage to make specific assumptions when solving problems.
More advanced graphics
Sage has sophisticated plotting capabilities. By combining the power of the Python programming language with Sage's graphics functions, we can construct detailed illustrations. To demonstrate a few of Sage's advanced plotting features, we will solve a simple system of equations algebraically:
var('x') f(x) = x^2 g(x) = x^3 - 2 * x^2 + 2
solutions=solve(f == g, x, solution_dict=True)
for s in solutions: show(s)
The result is as follows:
We used the keyword argument solution_dict=True to tell the solve function to return the solutions in the form of a Python list of Python dictionaries. We then used a for loop to iterate over the list and display the three solution dictionaries. Let's illustrate our answers with a detailed plot:
We created a plot of each function in a different colour, and labelled the axes. We then used another for loop to iterate through the list of solutions and annotate each one.
Visualising a three-dimensional surface
Sage does not restrict you to making plots in two dimensions. To demonstrate the 3D capabilities of Sage, we will create a parametric plot of a mathematical surface known as the "figure 8" immersion of the Klein bottle. You will need to have Java enabled in your web browser to see the 3D plot.
In the Sage notebook interface, the 3D plot is fully interactive. Clicking and dragging with the mouse over the image changes the viewpoint. The scroll wheel zooms in and out, and right-clicking on the image brings up a menu with further options.
Typesetting mathematical expressions
Sage can be used in conjunction with the LaTeX typesetting system to create publication-quality typeset mathematical expressions. In fact, all of the mathematical expressions in this article were typeset using Sage and exported as graphics.
A practical example: analysing experimental data
One of the most common tasks for an engineer or scientist is analysing data from an experiment. Sage provides a set of tools for loading, exploring, and plotting data. The following series of examples shows how a scientist might analyse data from a population of bacteria that are growing in a fermentation tank. Someone has measured the optical density (abbreviated OD) of the liquid in the tank over time as the bacteria are multiplying. We want to analyse the data to see how the size of the population of bacteria varies over time. Please note that the examples in this section must be run in order, since the later examples depend upon results from the earlier ones.
Time for action – fitting the standard curve
The optical density is correlated to the concentration of bacteria in the liquid. To quantify this correlation, someone has measured the optical density of a number of calibration standards of known concentration. In this example, we will fit a "standard curve" to the calibration data that we can use to determine the concentration of bacteria from optical density readings:
What just happened?
We introduced some new concepts in this example. On the first line, the statement import numpy allows us to access functions and classes from a module called NumPy. NumPy is based upon a fast, efficient array class, which we will use to store our data. We created a NumPy array and hard-coded the data values for OD, and created another array to store values of concentration (in practice, we would read these values from a file) We then defined a Python function called standard_curve, which we will use to convert optical density values to concentrations. We used the find_fit function to fit the slope and intercept parameters to the experimental data points. Finally, we plotted the data points with the scatter_plot function and the plotted the fitted line with the plot function. Note that we had to use a function called zip to combine the two NumPy arrays into a single list of points before we could plot them with scatter_plot.
Time for action – plotting experimental data
Now that we've defined the relationship between the optical density and the concentration of bacteria, let's look at a series of data points taken over the span of an hour. We will convert from optical density to concentration units, and plot the data.
What just happened?
We defined one NumPy array of sample times, and another NumPy array of optical density values. As in the previous example, these values could easily be read from a file. We used the standard_curve function and the fitted parameter values from the previous example to convert the optical density to concentration. We then plotted the data points using the scatter_plot function.
Time for action – fitting a growth model
Now, let's fit a growth model to this data. The model we will use is based on the Gompertz function, and it has four parameters:
What just happened?
We defined another Python function called gompertz to model the growth of bacteria in the presence of limited resources. Based on the data plot from the previous example, we estimated values for the parameters of the model to use an initial guess for the fitting routine. We used the find_fit function again to fit the model to the experimental data, and displayed the fitted values. Finally, we plotted the fitted model and the experimental data on the same axes.
Summary
This article has given you a quick, high-level overview of some of the many things that Sage can do for you.
Specifically, we looked at:
Using Sage as a sophisticated scientific and graphing calculator
Speeding up tedious tasks in symbolic mathematics
Solving a system of linear equations, a system of algebraic equations, and an ordinary differential equation

Tips For Success in Math
Attendance and Being an Active Learner
Do not miss a class. Math is cumulative, i.e. it's like building a house
one brick on another. If you miss a brick, the whole house will fall
apart. So attending all classes is important. However, your mere
presence in the classroom is not enough. You have to actively
participate in the classroom activities. You should take notes, ask
questions each time you don't understand, and actively participate in
discussions (we will have them a lot.) Just watching somebody else
solving problems or explaining things is not enough. Can you imagine,
for example, learning a basketball by just watching others play? Active
participation in class-work and practicing on your own are essential
part of learning.
Homework
Homework is the most important part of the learning process. Instructors
do not assign homework to make your life miserable (well most of the
instructors…) Many times after watching an instructor solving problems
on board, you may think you completely understand how to solve the
problems. However, that's a false feeling. You won't know if you truly
understand the material and can do the problem if you don't attempt the
homework. You need to attempt to solve all the problems and if you think
it's not enough do more. It's OK if you can't solve problems at the
first or second attempt. A common barrier in doing homework is when
after just reading a problem, some students think they don't know how to
solve it and move to the next one. Often there will be a similar
problem in the notes and/or text that can help you to get started. If
after several attempts and reading the textbook you still can't solve
some problems write down questions and ask me or at the tutoring center.
It is important to work on homework as soon after the lecture as
possible while the lecture is still fresh in your mind.
Finding a Study Partner / Forming a Study Group
Your classmates can be an excellent resource. Remember that one
of the best ways to learn is teaching others.
Exchange email and phone numbers with some students in the class.
If you need, I can meet with your study group outside of class time to
discuss specific topics or review for exams.
Getting Help
Use available free tutoring in Math Center located in CMS 121 (M-Th 11am-8pm and Sat 10am-2pm) and LRC.
See me during my office hours or make an appointment.
Get help before it's too late. Once you don't understand a concept or
problems in homework use the available help. Do not get behind. It will
be much harder later. |
You're getting a lot of good responses, but I'm surprised no one has asked yet, what sorts of math have you already learned? No point in telling you to learn algebra if you're already good at algebra.
For chemical engineering, relevant math is generally everything up through vector calc, ODEs, PDEs (much much later--mainly only if you plan on going to grad school, though it's a really good thing to be familiar with), and linear algebra.
EDIT: Also, try to be familiar with the expressions that give volume and surface area for 3D objects. This stuff comes up all the time when you take transport classes (which are hugely important for chemical). It's amazing how often people forget the surface area of a sphere, the volume of a cone, etc.
No point in telling you to learn algebra if you're already good at algebra.
To be honest, I would still tell him to learn algebra unless he's already taken calculus. I cannot tell you how many people I've seen go into Calculus 1 thinking they had a great grasp of algebra, only to discover how deeply mistaken they were.
So if you have a curve in y = mx+b form and you take the derivative what do you get? b is a constant it goes away, x drops a power so that it's x0 = 1 and you get m.
dy/dx = m
Or in the position vs time example v (velocity)
How useful is that?
have an x2 term in here, take a derivative again, you've got acceleration. Easy.
Then snap, and then jerk, but you won't use those much.
Side note physics courses without calc, are way more of a pain than the ones that are calc based ones.
Anti-derivatives too. An integral finds the area under a curve, it adds an infinite number of little areas to find the exact area. Mind boggling, but amazingly useful. Look at pictures of this and convince yourself that if there was an infinite number of those little rectangles, it would be the exact area, which would be really hard to find without using in integral.
After you take calc I, immediatly start pregaming for next semesters calc II, for me that was the most stressful "how am I ever going to do this" class.
Practices derivatives, and anti-derivatives, maybe look up what a sequence is, how is a series different? Also, brush up on trig, you'll need it for a kind of substitution and if you've forgotten it by then, you're in trouble. This is also where you'll need to know your exponential logarithmic stuff.
A professor once told me Calc II is really just a bunch of dirty tricks to get answers out of otherwise ugly functions.
Like trig, these problems are puzzles. You might get one that can be solved in two steps with a trig substitution, or fifteen iterations of integral by parts, or eight steps with partial fractions and get the correct answer every time. Pick the wrong one of a test, that clock on the wall starts moving a whole lot faster.
Calc III isn't bad, lot of calc I and some calc II in 3 dimensions. Review vectors, a lot. I took it at the same time I took physics, so that was nice. Extra vector practice. Get used to working in 3d coordinates. Also, linear algebra. I couldn't even remember how to deal with matrices when I got there, big mistake, picks right up where precalc left off, if your precalc bothered to touch on it for more than a week.
ODE is interesting. It's a revelation. It's absurdly useful. You get there and you say, "Ah, so this was why I was learning about integrals and derivatives. I can use this to model just about anything on a whim!"
You realize oscillations in electrical circuits behave the same way as your cars suspension as it goes down the road. That you can take some relations that you'd never be able to guess an equations for, and like magic it just about does it for you.
It's also a lot of structure and tricks. In this way it feels a little like Calc II all over again. You'll get a problem, and have to be able to say, "I know what method to try to solve this," and these kinds of problems, even if you're good are like puzzles and you can get unlucky, draw a blank and just have to try things.
Those are the main ones. You'll need to worry about. In my experience at least
Algebra and Trig are key! Try to visualize things in 3D! Also get used to making sure that all your units are in SI units. Try to look at something and realize that F=ma so that means that F= kg*m/s2 or N (haha). Also since you want to go into civil engineering, Calc 3 is going to be the impotent calc for you. It helps you understand how to solve equations with more than one variable and it really helps you wrap your head around 3D concepts! You don't just have an xy plane in real life, you have an x-axis, y-axis, and z-axis! |

Students are nervous about getting help in mathematics, don't be! I tell my students all the time that mathematics is challenging for all of us at one point or another. My intent is to provide clear and thorough explanations, and to present them in an environment in which the student is comfortable. Although I do not promise to make someone into an A+ student overnight, with regular help just about every student I have encountered makes significant improvements over time. Think about learning mathematics in the same way you would learn to play piano or learn another language. It takes time, patience, and LOTS of practice. |

Abstract
lthough formal definitions of mathematical concepts have been introduced since the Secondary School (SMP) through high school, but after college students have also use
fundamental concepts, when asked to identify or solve both problems using the concept of shadow or not (Marhan, 2007). This inability of students in using the basic concepts
and definitions of the function of the image can be attributed to the learning of mathematics in junior high and high school The research aims to determine the quality of high school students' skills in memahamai function. To realize the focus and purpose of the study focused on:
(1) high school students Mengeplorasi understanding on the definition and function forms(2) Testing for high school students' skills in presenting function in the representation of different This kind of research is the research by using a qualitative approach to the type of
descriptive research. Object in this research is the class XI student of SMAN 1 Malang Science and SMA Lab School of Malang with the material functions. The collection of
data used to determine which activities: Survey by Questionnaire, observation and testing. questionnaire used to assess students 'attitudes and behaviors in mathematics
learning in the subject and the test functions that are used to measure students' learning achievement
The results showed that: (1) students have low ability in understanding the concept of function. (2) students are more dominant this type of visual learning to understand the concept of function. |

Like a great interactive online textbook for math, one could easily get lost clicking from link to link. I bookmarked this page for further use. The visuals are great, the content is crisp and the information is easily accessible. This would be a great resource for teachers or for anyone looking for help with a math project.

Although I am new to Merlot, this isn't the first time I've been on mathworld. I have used this site before for research on a mathematics paper. Just for fun I checked out how diverse this site is and was even more impressed with it. I will bookmark it for future use. A good tool for instructors and students alike. Easy to use, and well organized.

The sheer volume of material here is staggering. This site certainly outlines pretty much anything the average mathematics student could want to know. I spent a good twenty minutes just looking around, making sure that everything I could want to know was there. Like those hard to remember formulae from high school geometry, for example, because who can remember those when they need them...in their college math classes. Anyway, this site was very dense, from a materials stand-point, but never difficult to navigate. I would highly recommend it to anyone without a textbook handy. It has pretty much everything you could be looking for.

The integral (or antiderivative) has long been used to determine the area under a curve, but finding the antiderivative can be a challenge. Other methods of integration can be cumbersome and give only a crude estimate of the actual area. Standard-slope integration is a fast, easy, and accurate method of numerical integration with results that are on par with those of classical integration methods concise article of thirty pages takes you on a short tour on how to write small programs using MATLAB. The presentation covers both script files and function files. Several programming constructs are illustrated with simple examples. Loops are discussed using the For and While loops, while decisions are implemented using the If Else and Switch Case constructs.This article is taken form the bestselling book "MATLAB for Beginners: A Gentle Approach." |

*Math for the Inquiring Mind
This is a course about using math to analyze and solve problems. Many of the decisions we face in modern life require consideration of the data that informs the choices. For example:
alternative methods of paying for college
a cost/benefit analysis for the purchase of a digital camera
comparisons of wages and cost of living factors in different locales
whether to lease a car or buy one the long term cost of borrowing money
the meaning of "a confidence level of 95%" in reported poll results
and so on…
In this course you'll learn about and apply a general process for making decisions, and solving problems, through the analysis of numeric data. Using a well-defined problem solving process, and a spreadsheet, students taking this course tackle problems using data analysis, visual analysis (charting), and statistical analysis. We've created an extensive set of narrated spreadsheet tutorials for this course that you'll watch to learn how a spreadsheet like Microsoft Excel can be used as a problem solving tool.
Problem Solving with Math: An Overview |top
Individuals who excel at solving problems tend to use guidelines to organize their thinking and to reach creative insights. This does not imply rigidly following a prescribed set of steps, but rather the use of a combination of discipline and creativity. Problem solvers use a general approach that varies with each unique situation.
Often the most critical steps in the problem solving process are the steps that occur before we actually frame or state the problem. What information or data do we have? What assumptions are we following? Who's perspective are we using? Is the problem stated as simply as possible?
Here are a few key points to consider when you are problem solving:
Keep the problem statement simple
Have a clear understanding of the current factors or circumstances (influencing the problem)
Collect accurate information or data
Use the right analytical tools and methods (to evaluate the problem, the roots cause(es), and identified the solution)
State the solution(s) in terms that can to acted upon
Identify how to evaluate or inspect whether the solution worked
Problem Statements: Be specific
Narrowing the scope of your problem will allow you to focus on the analysis that will get you to an appropriate solution.
Problem Statement Examples
Poor: Won't be able to attend college next semester
Good: Not enough money to pay next semester's tuition
Poor: SUNY College football games have lower attendance
Good: 20% fewer alumni attended SUNY College football games last year
If the problem statement is too broad you will spend unnecessary time determining specifically what you are trying to resolve.
Proposing Solutions: How Broad or Narrow is Appropriate
Studies of excellent problem solvers reveal that they seek the broadest possible solutions. They also consider all possible solutions, even those they believe may not be used. Considering all the options reduces the possibility of overlooking an effective solution. Example: Problem: Not enough money to pay next semester's tuition. Possible Solutions:
Drop out of school for a semester
Borrow money to pay for school
Find scholarship or other funding
Find a part-time or second job to make extra money
Start a business out of my home, for weekends and evening to make extra money
Each is a possible solution, yet none is merely the opposite of not enough money. Some solutions merely postpone the problem. Some solutions solve the problem on a temporary basis. Some solutions solve the problem now and in the future.
Learning Journal | top
Our philosophy for teaching and learning mathematics is based on the idea that learning happens best when you, the student, put new information into the context of what you already know. One technique we use to encourage this is called a learning journal. In this course you will keep a journal where you reflect on what you have learned and its meaning to you. The process of writing and reflecting is a good way to cement what you have learned into your memory, but it also serves a second purpose. Problem solving oftentimes requires the application of knowledge and techniques in new ways. In his book, The Reflective Practitioner, How Professionals Think In Action, Donald Schon [1] notes that standard educational practices often result in knowledge that is "specialized, firmly bounded, scientific and standardized." He goes on to say that "practice is characterized by indeterminacy" and that professional artistry requires that the practitioner to "reflect in action." In other words, professionals (problem solvers) take what they have learned in specialized, narrowly-bounded, contexts and apply that knowledge broadly by reflecting on their own thinking as they progress through the problem. You'll be asked to do this very thing by keeping a learning journal throughout this course.
Spreadsheet Tutorials: Beyond the Basics | top
A modern spreadsheet –pick any one you like– is a technological wonder. Just a sampling of the uses to which a modern spreadsheet can be applied includes:
as a data management tool
for presenting and sharing data
for data analysis
for statistical analysis
for graphing and visual analysis
mathematical modeling
keeping lists
tracking progress on a project
Notice that the uses listed here are not things like "add columns" or "sort rows". These are higher order uses, the kinds of things you do when you use a spreadsheet as a problem solving tool. We've created an extensive series of narrated tutorials to help you learn how to go beyond the basics and learn to use a spreadsheet as a problem solving power tool. References: [1] Schon, D. (1983).

In eleven chapters by leading scholars, The Market Makers provides a detailed but highly readable analysis of how retailers have become the leading drivers of the new global economy. The analytic core is the "market-making perspective," which refocuses economic analysis away from factories and production to markets and market-making.
Once the social and commercial core of the rural community, the village shop has become as much the victim of the accelerating pace of social and economic change as the parish school and pub, and has now almost entirely disappeared from everyday life. This book charts the development and history of the village shop and it's slow demise.
Offers an alternative model to the dominant view of economic development, a model that liberates and fosters the natural capacities of local businesses to grow and prosper. This book shows readers how easy and beneficial it is to "go local" in their four key spending categories: goods, services, energy and finance.

This is a free, open textbook that is part of the Connexions collection at Rice University. "Few areas in our world today remain untouched by the influence of the new technology and its impact on education. Teachers must now devise new strategies for teaching and the exchange of information in classrooms with a view to improving Literacy and the comprehension of English among speakers of English-based creoles. We advocate research and experimentation with digital tools as one of the ways of involving young teachers in possible projects that will challenge their own Literacy as well as that in the wider society. THIS COLLECTION of articles was sourced on the Connexions server with precisely this aim in mind. The first article on the history of Literacy and the evolution of the Connexions (OER)model gives us the signal that the proliferation of digital tools and their use in education will radically alter the face of teaching and learning in the coming decades. The second article explores the topic of the changing learning styles of digital learners. We are in for an educational adventure that has implications for the way Literacy can grow and be a source of enjoyment among dialect speakers of English. These articles form a framework for an exploration of how digital tools can be used to enhance Literacy on our campus. The COLLECTION will be used for a discussion of the issues in workshops and as supplemental reading in Literacy related courses. It has evolved out of an initial exploration of the topic of technology and Literacy. Onr hopes that it will attract attention and feedback from others in the field of Literacy and the new technology.״

with these textbooks is they focus too much on the means and not enough on the end.
Most lessons are structured around an "investigation" where the students complete an activity ultimately leading them to a new conjecture, formula, or theorem. Next, one or two difficult examples in the form of a word problem is explained to illustrate the new concept. Finally, a challenging problem follows. My biggest issue is the textbook does not explicitly state the new content to be learned. If students are absent, they cannot stay caught up in class by reading the textbook unless they complete the investigation. The examples in the book are too difficult for students to comprehend without doing easier problems first, which do not exist. The textbook also emphasizes the use of calculators and frequently asks questions in terms of calculator lingo which detracts from actual learning occurring.
The discovering series does its best to get students interested and excited about math, but it ultimately leaves them confused and frustrated. The textbooks do not prepare students for standardized tests or college math. Look elsewhere.
.
There are a lot of algebra textbooks out there. A lot of them seem to be stuck back in the 1980's or worse. It's not just using color graphics such as is done in the Discovering Algebra book, but using color graphics well. It's not just building learning around a project, but designing a project around which to learn. I think anyone can come up with a project, but designing projects to get the maximum learning out of each project is what I think the authors of this textbook accomplished.
This is the textbook I would like to see translated and adopted for use in Israeli schools. It is exciting to read through and I think it would take away one of the key barriers to learning math for many students; that is that they don't see how any of what they learn in class relates to life outside of the math classroom. With this book I think they could.
I expect that a book with a subtitle of "An Investigative Approach" would teach concepts through discovery learning. That is the trend for learning/teaching nowadays. In fact, this book teaches math concepts like every other math book, it just has little activities to reinforce the concepts. I wasn't that impressed by the activities, either. What I want and can't find is a math book of discovery learning activities that help students uncover the ideas by connecting previous knowledge in a new way. I also want a book that provides meaningful, real-world applications to the concepts learned. This book isn't it.
I had to use this book when I taught a large class of high school Algebra students. I soon found that the examples and exercises were very poorly done. I had to work twice as hard as a teacher to prepare meaningful lessons and assignments because the book was so poorly written.
I strive to instill a love of learning in my students. The Key Curriculum press books also encourage students to enjoy the learning process, to explore, to discover patterns and mathematical relationships. The book is engaging and involves the learner on every lesson.
I wanted to purchase a copy of my son's math text so that he wouldn't need to carry his school copy back and forth. (The book is quite heavy.) So this was a great find with an excellent price and the seller shipped very quickly.
I had a 4.0 GPA in my math major at a top 20 private university in the U.S. and have loved solving math problems my entire life. My eighth grade son currently has the misfortune of being required by his prep school to use this book. The book is plain awful, full stop. This is the very first year my son's school has used this book, and I am going to do all I can to ensure it is the last. |

The graphing calculators that are most commonly used in pre-calculus and
Calculus I are the TI-82/83/84 series and the TI-85/86 series. Specifically, the standard
TI-86 will be what this manual is based on, and is shown below on the right.
TI-83 TI-86
These calculators are similar to each other and both have the functionality needed
for mathematics up through Calculus I. The main difference between them is the TI-83 is
generally more user friendly, while the TI-86 has more features and functionality. Both
calculators have a black and white screen on the top half and a large keypad on the
bottom half. The TI-82 and TI-84 are very similar to the TI-83, and the TI-85 is very
similar to the TI-86. Keep in mind that there are some subtle differences between
calculators of the same series.
Below is a closer look at the keypads. Both have the same number of keys, but
Some are in different places and some are on one keypad and not the other. Both
keypads have three "levels" of keys. As you can see, there is white writing on the keys
themselves, yellow to the upper-left of the keys, and green (TI-83) or blue (TI-86) to the
upper right of the keys.
TI-83 Keypad TI-86 Keypad
To use the white level you simply type the key. For example, to enter a "5"
simply press the [ 5 ] located in the middle of the keypad. However, if you want to use
the yellow functions, press the [ 2nd ] key followed by the button directly below it. For
example, to enter the number "Pi", press the yellow [ 2nd ] and then press the [ ^ ] key
located on the right middle side of the keypad. The blue level of the keypad gives access
to the alphabet. For upper case letters, press the [ ALPHA ] key followed by the key
directly below the letter. And, for lower case letters, press [ 2nd ] [ ALPHA ] then the
key directly below the letter. For example, to enter an "E" using the TI-86, press
[ ALPHA ] [ ^ ]. To enter an "e" using the TI-86, press [ 2nd ] [ ALPHA ] [ ^ ].
Graphing – Inputting Equations (TI-86)
Overview
To graph a function on the TI-86, the equation must be written in "y = f(x)" form.
Once this is accomplished, a graph can be made. The graph will be displayed in
the window dimensions that are currently set. To change the window dimensions
refer to the section titled "Window Adjust".
Procedure
1. From the home screen press [ GRAPH ] to display the graphing options
2. Press [ F1 ] to select " y(x)= "
3. Press [ CLEAR ] if the " y1=" line is not blank
4. Enter the equation, pressing [ x-VAR ] whenever an "x" is needed
5. Once the equation is entered in, press [ 2nd ] [ F5 ] to select "GRAPH"
6. Your equation will be graphed in the window
Example
Graph the function y = x3 – 2x2 – x + 1.3
1.) 2.)
3, 4.) 5, 6.) Graphed in (-5,5) x (-5,5).
Graphing – Multiple Equations / Line Style (TI-86)
Overview.
The TI-86 allows multiple equations to be displayed simultaneously. The line
style can also be changed to help distinguish between graphs.
Procedure
1. Complete steps one through four of "Inputting Equations"
2. Press the down arrow
3. Complete steps one through four of "Inputting Equations" with a different
equation
4. Press [ MORE ], and move the cursor back to the "y1=" line
5. Press [ F3 ] to select "STYLE". Notice the diagonal line, on the left, is now
bold. This is what the first graph will be graphed as. Pressing "STYLE"
multiple time will shuffle through different style options
6. Press [ 2nd ] [ F5 ] to graph the equations
Example
Graph the function y = sin (x) (bold), and y = cos (x) (not-bold)
1, 2, 3, 4.) 5, 6.)
Window Adjust (TI-86)
Overview
When viewing the graph of a function, there may be a "best" view of the graph.
Too close and the general shape of the graph may not be seen, and too far and the
details of the graph may go unnoticed. The TI graphing calculators allow the user
to look very closely at certain parts of a graph, similar to looking under a
microscope. Also, the user is allowed to look at a much bigger area of the graph.
The four most basic and most used methods to adjust the viewing window are 1.)
Manually setting the x and y intervals in the "WIND" function, 2.) "ZIN" (zoom
in) under the "ZOOM" function, 3.) "ZOUT" (zoom out) under the "ZOOM"
function, and 4.) "BOX" under the "ZOOM" function.
Procedure
Manually setting the x and y intervals in the "WIND" function
1. Graph the function and view it
2. Press [ GRAPH ] then [ F2 ] to select "WIND"
3. Using the up/down arrow keys, select the field to set and press [ CLEAR ]
4. Type in the value wanted for each field keeping in mind that xMin must be a
smaller number than xMax, and yMin must be smaller that yMax. xScl and
yScl stand for x-scale and y scale, this is the distance between tick marks
5. Press [ F5 ], when finished, to graph it
"ZIN"
1. Graph the function and view it
2. Press [ F3 ] to select "ZOOM"
3. Move the cursor to the center of the area to zoom in on
4. Press [ F2 ] to select "ZIN" and press [ ENTER ]
"ZOUT"
1. Graph the function and view it
2. Press [ F3 ] to select "ZOOM"
3. Move the cursor to the center of the area to zoom in on
4. Press [ F3 ] to select "ZOUT"and press [ ENTER ]
"BOX" - This uses a user defined section of the window and blows it up to fill the
entire window.
1. Graph the function and view it
2. Press [ F3 ] to select "ZOOM"
3. Press [ F1 ] to select "BOX"
4. Use the arrow keys to move the cursor to one corner of the box that will fill the
custom window and press [ ENTER ]
5. Use the arrow keys to move the cursor to the opposite corner of the box and
press [ ENTER ]
(Examples on next page)
Examples
Examine the function y = sin (1/(x-2)) + 1

press [ ENTER ]
3.) Position the cursor near 4.) The box is now blown up in the
x = 3, y = -1, press [ ENTER ]. window.
FMIN, Finding the Minimum Value of a Function (TI-86)
Overview
Often in Calculus, the minimum and maximum values of functions are of interest.
This page shows how to find the local minimum of a function on an interval. To
find the local maximum, simply repeat this example but instead use the "FMAX"
function instead of the "FMIN" function in #3 below.
Procedure
1. Graph the function and view it
2. Press [ MORE ]and then press F1 to select "MATH"
3. Press [ F4 ] to select "FMIN"
4. Use the left/right arrow keys to select the left bound of the interval containing
the minimum value and press [ ENTER ]
5. Use the left/right arrow keys to select the right bound of the interval
containing the minimum value and press [ ENTER ]
6. Use the left/right arrow keys to select a guess close to the minimum value and
press [ ENTER ]
7. Your minimum value will be returned in x-y coordinates
Example
Find the local minimum value of the equation y = x3 - 2x2 - x + 1.3
1, 2.) Graphed in (-5,5) x (-5,5). 3.)
4.) Select the left bound. 6.) Select a guess.
5.) Select the right bound. 7.) Minimum value is displayed.
ISECT (intersect) TI-86
Overview
To find the intersection point of two graphs, the "ISECT" function can be useful.
Although, the "TRACE" function can do a similar job, the "ISECT" function can
return the result faster and more accurately. To use this function, at least two
equations must be entered and graphed with the intersection point in the viewing
window. The "ISECT" function asks for the first function and then the second
function it intersects and then asks for a guess. (The reason for the guess is that,
in case there are two intersection points, the calculator returns the right one.)
Procedure
1. Graph at least two functions and view them with the intersection point in the
viewing window
2. Press [ MORE ] and [ F1 ] to select "MATH"
3. Press [ MORE ] and [ F3 ] to select [ ISECT ]
4. Use the up/down arrows to move the cursor to the first function and press [
ENTER ]
5. Use the up/down arrows to move the cursor to the second function and press [
ENTER ]
6. Use the left/right arrows to move the cursor near the intersection point and
press [ ENTER ]
Example
Find the first intersection point of Sin (x) and Cos (x) on the positive x-axis.
1.) Sin (x) and Cos (x) are graphed on 2.)
the x-interval from 0 to 2Pi, Sin (x) is
the bold curve.
3.) First curve 4.) Second curve
(continued on next page)
5.) Guess 6.) Note: 1/sqrt (2) = .707106.....
and Pi/4 = .78539....
dy/dx (TI-86)
Overview
Checking your derivatives using the TI graphing calculators can be very helpful
when doing homework.
Procedure
1. Graph the function and view it
2. Press [ MORE ] and [ F1 ] to select "MATH"
3. Press [ F2 ] to select dy/dx
4. Move the cursor or type in the x-value of the point where the derivative is to
be evaluated and press [ ENTER ]
Example
Verify that the top hemisphere of the unit circle, y = √ (1 - x2), has a derivative of
-1 at the point on the circumference 45 degrees up from the x-axis. This is the
point (1/√ 2, 1/√ 2) or approximately (.707, .707).
1.) 2.)
3.) Moving the cursor. 4.) Type in the x value.
5.)
Integrals (TI-86)
Overview
It is often convenient to check answers to homework using the graphing
calculator. Though it's no substitute for doing integrals, the TI graphing
calculators allow the user to find numerical values of definite integrals.
Procedure
1. Graph the function and view it, making sure the lower and upper bounds of
the integral are within the viewing window
2. Press [ MORE ] and then [ F1 ] to select "MATH"
3. Press [ F3 ] to select the "integrate" function
4. Move the cursor or type in the lower bound, press [ ENTER ]
5. Move the cursor or type in the upper bound, press [ ENTER ]
Example
Find the surface area of the top hemisphere of a circle with radius 1. From
geometry we know this is (Pi)*(r2)/2 = (Pi)*(12)/2 ≈ 1.57079 ... , now we'll check
using the calculator's integrate function.
1.) x2 + y2 = 12 2, 3.)
4.) 5.)
6.) The calculator's numerical answer of
1.57193.... is off by a couple thousandths.
Glossary (TI-86)
Home Screen The starting point for doing anything with the TI graphing calculators. To
get to the Home Screen use the QUIT function. Using the TI-83 press [
2nd ] [MODE ], with the TI-86 press [ 2nd ] [ EXIT ].
Inflection Point The point were a graph changes from concave up to concave down or
vice versa. For example, it can be shown that the inflection point of the
equation y = x3 is at (0,0); here, the graph changes from concave down to
concave up.
int (x) The function on the TI calculators that returns the greatest integer less than
or equal to the value within the parentheses. For example, int (3.3) returns
3 and int (-3.3) returns "-4". If this is not clear, draw a number line and
demonstrate it to yourself.
Integral In simple terms, the area above the x-axis and below the graph of a
function, between two endpoints.
Radian Mode When working with trigonometric functions, the user has to be aware of
whether degrees or radians are being used. If the user assumes the
calculator is in degree mode, but it's really in radian mode, the calculator
will give "bad" answers. To change from degree to radian mode or vice-
versa, from the home screen press [ 2nd ] [ MORE ] to select the "MODE"
function. Then, highlight the "Radian" option. For most situations in Pre-
Calculus and Calculus I, you will want the entire left column of the
"MODE" screen highlighted.
Style The function on the TI graphing calculators that changes the style of the
line of the graph. Standard line style is a line one-pixel thick. Other
options are dotted lines, bold lines, lines with shading below or above.
This is used to distinguish between multiple functions displayed at the
same time.
Trace The function on the TI calculators that uses a cursor to trace over the
graph displaying the x and y coordinates. The left/right arrow keys move
the cursor position along the graph of an equation, the up/down arrow
keys move the cursors to another graph when multiple equations are
displayed.
Window The defined area displayed on the screen of the TI calculators. The
window function will let the user adjust the x and y intervals that will
define the boundaries of the displayed graphs. Example x and y intervals
on the TI graphing calculators would be: x-min = -10, x-max = 10, y-min
= -10, y-max = 10. This would set the window boundaries to a 20 by 20
rectangle centered at the origin (0,0).
"y=f(x)" form The required form of the equation needed, to be entered into the TI
graphing calculators, when graphing in the x-y plane. For example
" y - 2x = x2 + 2" is not in y = f(x) form, whereas "y = x2 + 2x + 2" is in
"y = f(x)" |
Mathematics - General (484 results)
The purpose of this book, as implied in the introduction, is as follows: to obtain a vital, modern scholarly course in introductory mathematics that may serve to give such careful training in quantitative thinking and expression as well-informed citizens of a democracy should possess. It is, of course, not asserted that this ideal has been attained. Our achievements are not the measure of our desires to improve the situation. There is still a very large "safety factor of dead wood" in this text. The material purposes to present such simple and significant principles of algebra, geometry, trigonometry, practical drawing, and statistics, along with a few elementary notions of other mathematical subjects, the whole involving numerous and rigorous applications of arithmetic, as the average man (more accurately the modal man) is likely to remember and to use. There is here an attempt to teach pupils things worth knowing and to discipline them rigorously in things worth doing.<br><br>The argument for a thorough reorganization need not be stated here in great detail. But it will be helpful to enumerate some of the major errors of secondary-mathematics instruction in current practice and to indicate briefly how this work attempts to improve the situation. The following serve to illustrate its purpose and program:<br><br>1. The conventional first-year algebra course is characterized by excessive formalism; and there is much drill work largely on nonessentials.
In issuing this new volume of my Mathematical Puzzles, of which some have appeared in the periodical press and others are given here for the first time, I must acknowledge the encouragement that I have received from many unknown correspondents, at home and abroad, who have expressed a desire to have the problems in a collected form, with some of the solutions given at greater length than is possible in magazines and newspapers. Though I have included a few old puzzles that have interested the world for generations, where I felt that there was something new to be said about them, the problems are in the main original. It is true that some of these have become widely known through the press, and it is possible that the reader may be glad to know their source.<br><br>On the question of Mathematical Puzzles in general there is, perhaps, little more to be said than I have written elsewhere. The history of the subject entails nothing short of the actual story of the beginnings and development of exact thinking in man. The historian must start from the time when man first succeeded in counting his ten fingers and in dividing an apple into two approximately equal parts. Every puzzle that is worthy of consideration can be referred to mathematics and logic. Every man, woman, and child who tries to "reason out" the answer to the simplest puzzle is working, though not of necessity consciously, on mathematical lines. Even those puzzles that we have no way of attacking except by haphazard attempts can be brought under a method of what has been called "glorified trial" - a system of shortening our labours by avoiding or eliminating what our reason tells us is useless. It is, in fact, not easy to say sometimes where the "empirical" begins and where it ends.<br><br>When a man says, "I have never solved a puzzle in my life," it is difficult to know exactly what he means, for every intelligent individual is doing it every day. The unfortunate inmates of our lunatic asylums are sent there expressly because they cannot solve puzzles - because they have lost their powers of reason. If there were no puzzles to solve, there would be no questions to ask; and if there were no questions to be asked, what a world it would be! We should all be equally omniscient, and conversation would be useless and idle.<br><br>It is possible that some few exceedingly sober-minded mathematicians, who are impatient of any terminology in their favourite science but the academic, and who object to the elusive x and y appearing under any other names, will have wished that various problems had been presented in a less popular dress and introduced with a less flippant phraseology.
Bringing to life the joys and difficulties of mathematics this book is a must read for anyone with a love of puzzles, a head for figures or who is considering further study of mathematics. On the Study and Difficulties of Mathematics is a book written by accomplished mathematician Augustus De Morgan. Now republished by Forgotten Books, De Morgan discusses many different branches of the subject in some detail. He doesn't shy away from complexity but is always entertaining. One purpose of De Morgan's book is to serve as a guide for students of mathematics in selecting the most appropriate course of study as well as to identify the most challenging mental concepts a devoted learner will face. "No person commences the study of mathematics without soon discovering that it is of a very different nature from those to which he has been accustomed," states De Morgan in his introduction. The book is divided into chapters, each of which is devoted to a different mathematical concept. From the elementary rules of arithmetic, to the study of algebra, to geometrical reasoning, De Morgan touches on all of the concepts a math learner must master in order to find success in the field. While a brilliant mathematician in his own right, De Morgan's greatest skill may have been as a teacher. On the Study and Difficulties of Mathematics is a well written treatise that is concise in its explanations but broad in its scope while remaining interesting even for the layman. On the Study and Difficulties of Mathematics is an exceptional book. Serious students of mathematics would be wise to read De Morgan's work and will certainly be better mathematicians for it.
This work outlines for students of the third and fourth high-school years a more advanced and more thorough course in applied business mathematics than the ordinary first-year course in elementary commercial arithmetic. The attempt has been made to construct a practical course which will contain all the essential mathematical knowledge required in a business career, either as employee, manager, or employer.<br><br>The fact that the field has been covered in this text both more intensively and more comprehensively than it has yet been covered in other texts, and the added fact that the material gathered together has stood the test of six years experience in the teaching of large and varied classes of the fourth year in a city high school, seem sufficient warrant for its publication.<br><br>The work is adapted not only for use in the classroom but also as a reference manual for those actively engaged in business life. Thus it will be found a practical guide for, young employees who wish through private study to master the fundamental mathematics involved in "running a business." The tabulations, forms, illustrative examples, charts, logarithmic applications, and simple rules, are all applicable to the financial and other mathematical problems which business presents. Lack of knowledge of this side of a business, or inability to work out its mathematics, often results in haphazard guessing where accurate and careful calculations are required.
William Timothy Call was a mathematician and an individual interested in using mathematics to improve daily life. In A New Method in Multiplication and Division, Call presents a method he personally devised to solve multiplication and division problems. In his introduction the author acknowledges that the method presented in this book is of no great significance, rather it is a curious way of attacking a problem that likely differs from what the reader has been taught. It is clear from the beginning that this is a book aimed at those with a keen interest in math. The book opens with Call's method for solving simple multiplication problems, before progressing to his method for problems of division. A New Method in Multiplication and Division is a brief work and one that will appeal to those for whom mathematics is a hobby. The subject matter is largely trivial, and while the methods detailed are effective, they are presented largely as a novelty. Those who are passionate about mathematics will likely enjoy the casual approach of the author and the general tone of the book. For readers passionate about mathematics and problem solving, William Timothy Call's A New Method in Multiplication and Division is recommended. This is not a textbook or a resource guide, but rather a lighthearted presentation of a simple but alternative mathematical approach, intended to entertain and inform the reader.

Rapid ArithmeticQuick and Special Methods in Arithmetical Calculation Together With a Collections of Puzzles and Curiosities of Numbers
by T. O'Conor Sloane
Rapid Arithmetic: Quick and Special Methods in Arithmetical Calculation, authored by doctor and lawyer T. O'Conor Sloane, is a guidebook to improving your mental math skills. The book is a mixture of valuable and applicable strategies for solving problems of arithmetic, and simple and amusing mental diversions. It is a work that treats the subject of mathematics as something that can be enjoyed. Rapid Arithmetic opens with a brief section on notation and signs before delving more fully into the subject matter. Separate chapters are presented covering addition, subtraction, multiplication and division, as well as fractions, the decimal point, exponents, and several other topics. Each chapter consists of an overview of the topic, as well as a variety of different strategies for tackling different mathematical problems. The author presents short practice activities throughout the work, intended to both reinforce the lesson and serve as fun diversion for the reader. T. O'Conor Sloane has a gift for making a challenging subject entertaining. Rapid Arithmetic is not a book only for the math enthusiast, but for anybody that sees the value in honing their arithmetical skills. It is a well-written and clearly presented treatise on the topic. Rapid Arithmetic: Quick and Special Methods in Arithmetical Calculation is the rare text about mathematics that can appeal even to one not interested in the subject. Sloane's methods can actually improve the daily life of the reader by allowing one to more quickly work out common math problems, and for this reason his work is highly recommended.
As in the Primary Arithmetic, so in this Intermediate Arithmetic, the aim is to render the subject attractive to the pupil, without sacrifice of serious intent. The pupils self-activity is encouraged. By the selection, so far as possible, of problems bearing on the practical life of to-day, the pupil is made to feel that he is engaged in studies that are truly worth his while. Our constant aim has been to lay emphasis upon fundamental operations. Frequent reviews enable the pupil to hold in mind the new knowledge he has acquired. As in the Primary Arithmetic, so here, the technique of arithmetic is simplified, with the aim of securing greater economy of effort. Thus the subject of ratio is robbed of some of its terrors by its identification with a common fraction. A proportion expresses the equality of two common fractions. There is no need of the terms antecedent and consequent. Again, there is given, as an alternative, a simplified method of reading decimal fractions. After the theory of decimal fractions is understood,.425 is read Point, four, QPfH.
In this book, all the principles of Arithmetic are fully developed, and sufficient examples are given to fix them on the mind.<br><br>When a student is very apt and thoroughly understands the Primary Lessons, he may omit the Elementary, and immediately take up this book, which is complete in itself.<br><br>I have discarded puzzles of every kind, which only perplex the student without advancing him a step in science.<br><br>A few simple principles of algebra are introduced, in order to elucidate more clearly, the different functions of interest, the series of equal ratios, and the square and cube root.<br><br>Problems in mensuration are also given, the principles of which are derived from Geometry.<br><br>Arithmetic is a pure mathematical science, and if its principles are systematically developed, the student will progress with easy and rapid steps, and when he has finished this book, he will discover that he has already so far ascended the hill of science that a retrospect will present to him many beauties which are greatly enhanced when seen in their harmonious relation to each other.
The basis of the present elementary treatise on Applied Mathematics was formed by a manuscript written by my father; on his death the task devolved upon me of completing the work, and by various additions the original scope of the book has been considerably extended.<br><br>It is designed mainly for use in Schools and for various public examinations, and I am not without hope that the explanation of the principles of the subject herein contained is sufficiently detailed to render it valuable to private students who are not in a position to obtain much assistance from teachers.<br><br>I have adopted the arrangement, which is now generally approved, of considering successively kinematics, kinetics, and forces in equilibrium. The chief innovation is the introduction of a separate chapter on Graphical Statics. Throughout, the C. G. S. system has been treated side by side with the foot-lb.-sec. system.<br><br>A large number of worked-out examples has been added in illustration of every point of importance throughout the book. The most fundamental propositions have been treated in the most elementary manner consistent with giving valid proofs, most of them can be mastered by students whose geometrical knowledge does not extend beyond the first three books of Euclid, but in order to give completeness, trigonometrical methods have been added, usually in smaller type.
The orientalists who exploited Indian history and literature about a century ago were not always perfect in their methods of investigation and consequently promulgated many errors. Gradually, however, sounder methods have obtained and we are now able to see the facts in more correct perspective. In particular the early chronology has been largely revised and the revision in some instances has important bearings on the history of mathematics and allied subjects. According to orthodox Hindu tradition the Surya Siddhanta, the most important Indian astronomical work, was composed over two million years ago! Bailly, towards the end of the eighteenth century, considered that Indian astronomy had been founded on accurate observations made thousands of years before the Christian era. Laplace, basing his arguments on figures given by Bailly considered that some 3,000 years B. C. the Indian astronomers had recorded actual observations of the planets correct to one second; Playfair eloquently supported Bailly's views; Sir William Jones argued that correct observations must have been made at least as early as 1181 B. C.; and so on; but with the researches of Colebrooke, Whitney, Weber, Thibaut, and others more correct views were introduced and it was proved that the records used by Bailly were quite modern and that the actual period of the composition of the original Surya Siddhanta was not earliar than A. D. 400.<br><br>It may, indeed, be generally stated that the tendency of the early orientalists was towards antedating and this tendency is exhibited in discussions connected with two notable works, the Sulvasutras and the Bakhshali arithmetic, the dates of which are not even yet definitely fixed.
This, the fourth and final book of the Walton and Holmes series of arithmetics, is intended for use in the eighth year of an eight-grade elementary course, and in either the eighth or. the eighth and ninth years of a nine-grade course. It gives to the grammar school pupil a final view of the subject, and provides for him a reference arithmetic that will be of use to him after leaving the elementary grades. The treatment of the subject of arithmetic herein given is neither exhaustive nor extremely theoretical. The aim in the minds of the authors has been to produce a useful and usable text-book adapted to the needs and capabilities of eighth and ninth grade pupils. For this reason, the plan of the book is strictly topical rather than spiral, in order that each topic may be given such intensive study as is possible and desirable for grammar school pupils, not only for a mastery of the subject, but as a direct preparation for the mathematics of the secondary school where the topical treatment prevails. Each topic is treated as fully as the limits of a text-book will permit, and is presented with full appreciation of its practical applications in the problems of the workshop, the factory, the counting room, and everyday experience. This is an arithmetic pure and simple, and there has been no attempt at the introduction of novelty either in the presentation of topics or in the selection of problems. The authors have selected reasonable problems, and have avoided the use of those which would be unlikely to occur in ordinary business experience.
The course of study in American high schools is in process of extensive change. The change commenced with the introduction of new subjects. At first science began to compete with the older subjects; then came manual training, commercial and agricultural subjects, the fine arts, and a whole series of new literary courses. In the beginning the traditional subjects saw no reason for mixing in this forward movement, and such phrases as "regular studies," "substantial subjects," and "serious courses" were frequently heard as evidences of the complacent satisfaction with which the well-established departments viewed the struggles for place of the newer subjects. Today, however, the teachers of mathematics and classics are less anxious than formerly to be classified apart. Even the more conservative now write books on why they do as they do and they speak with a certain vehemence which betokens anxiety. They also prepare many editions of their familiar type of textbook, saying of each that it is something which is both old and new. All these indications make it clear that the change in the high-school curriculum which began with the introduction of new subjects will not come to an end until many changes have been made in the traditional subjects also.<br><br>Over against the obstinate conservatism of some teachers is to be set the vigorous movement within all subjects to fit them effectively to the needs of students. The interest of today is in supervised study, in better modes of helping students to think, in economy of human energy and enthusiasm. This means inevitably a reworking of the subjects taught in the schools. It is the opportunity of this generation of teachers to work out the changes that are needed to make courses more productive for mental life and growth.<br><br>During this process of reform, mathematics has changed perhaps less than any other subject.
The folio-wing letter -was addressed by the late Professor of Mathematics, Uc. in Vermont College, toR. M.Patterson, M.D. Prof of Math, and Nat. Phil. in the University of Pennsylvania. Dear sib, Agreeably to your request I have cursorily examined Gummere sTreatise on Surveying, and conceive that the author has performed all that his preface promises. The subject is logically distributed and arranged, and the principles correctly and perspicuously displayed. The examples are very properly multiplied and ingeniously varied, so as to prepare the student for the most unusual cases. That the authors success in the publicationmay equal his high reputation for science, is a wish, which (as far as good wishes go) ought to be as satisfactory to him, as it is sincere on the part of Yours, with very high respect and esteem, James Dean. I Extract from a letter from Samuel Knox, Esq. principal of the Baltimore College. I received and submitted to our Mathematical Professor, Gummere sSurveying. We approve of the work, and as often as any of our students want an author on that branch, we shall recommend it. I remain very respectfully, your obedient, humble servant, c.SAMUEL Knox. I fully concur with the gentlemen who have already given recommendations of Gummere sTreatise on Surveying, in considering the work as well calculated to give youth a correct knowledge of the principles of Surveying, and that it is to be preferred to any treatise on that subject, known in this country. Elijah Slack, Prof, of Math, in Princeton College. For sale by the publishers: Solutions to the Miscellaneous Questions in Gummere sSurveying. By the Author. Price twenty-five cents. Also, a Stereotype edition of Mathematical Tables, containing Tables of Latitude and Departures, of Logarithms from one to ten thousand; and artificial Sines, Tangents and Secants; the whole carefully revised and compared with the most correct European editions.
The old order in mathematics teaching is rapidly giving way to a newer one more interesting, more vital, and more effective. Formerly, all phases of arithmetic were taught in the seventh and eighth grades. In the ninth grade, the foundations of algebra were laid. The latter had practically no connection with the arithmetic that came before nor with the geometry that came after. It was mostly the juggling of symbols that symbolized nothing. This algebra took on some meaning later for the few who continued the study of mathematics in higher schools. But for the many, it never functioned.<br><br>With the organization of the junior high schools has come a reorganization of mathematics. It is now taught in cycles, each complete in itself and adapted to the needs and abilities of the pupil, regardless of whether he continues the study of mathematics in school or applies it in the office, store, or shop. The purpose of the junior cycle is to give the pupil a broad knowledge and usable power and skill in the field of elementary mathematics. This cannot be done by the old tandem courses of arithmetic, algebra, geometry, and trigonometry. Nor will alternate bits of formal algebra, geometry, and trigonometry solve the problem. The result is a mastery of none and a confusion of all.<br><br>In this series the elements of arithmetic, geometry, algebra, and trigonometry are taught as one subject. Book One is largely arithmetical, but it uses the graph and the formula.
It has been urged that the investigation and progress that have characterized other branches of the school curriculum have been lacking in so far as mathematics is concerned, especially in the case of mathematics as applied to secondary schools. This is doubtless due largely to the fact that mathematics, as a pure science, is not so susceptible to theory as is a subject whose limitations are not so closely drawn, and whose subject matter is more open to speculation. In spite of this fact, however, educators have dreamed of a more ideal course in mathematics; a course which would give better and larger returns for the time spent in study, and a course which would remove from mathematics the stigma which it so often bears, of being the bête noir of the average high school student.<br><br>The teacher of secondary mathematics has his choice between what might be called the natural and the artificial incentives. Under the natural incentives fall the following: a - the uses of mathematics in the activities of life; b - the charm of achievement which comes with the solving of problems; c - the gain of mental power, of the ability to reason clearly to a definite conclusion. Among the artificial incentives, the following are the most usual and most powerful: a - graduation from the high school; b - preparation for college; c - the winning of some special prize or honor; d - the avoiding of suspicion of mental weakness.
This book carries forward through the second high-school year the combined type of material and the plan of treatment of First-Year Mathematics. The two texts together cover the essentials of what is commonly required of all pupils in the first two years of secondary schools in this country, and include, in addition, the elementary notions of plane trigonometry through the solution of right triangles, as well as an introduction to some topics of formal algebra not usually treated in secondary texts. Each book constitutes a well-balanced and not over-heavy year of work. This material so arranged at the same time opens to the pupil a broader, richer, a more useful and therefore a more alluring field of ideas than do the two subjects of algebra and plane geometry treated separately.<br><br>It is felt that the material and treatment of these books lays for the beginner a more stable foundation for future work than does the usual order of a year of formal algebra, followed by a year of formal demonstrative geometry, or of these subjects in the reverse order. This judgment, founded on our own experience, is confirmed by a recent extended inspection of schools abroad. In England as well as in Germany and France, the best secondary schools were seen to be using the methods of combined mathematics almost exclusively, with seeming advantage to their pupils.<br><br>Second-Year Mathematics lays chief emphasis on geometry, as did the First-Year Mathematics on algebra. To take up the work of these texts then requires no abrupt departure from the order of subjects now prevailing in secondary curricula.
The work now presented to the public had its origin in a desire which I felt to draw up an Essay on the principles and applications of the mechanical sciences, for the use of the younger members of the Institution of Civil Engineers. The eminent individuals who are deservedly regarded as the main pillars of that useful Institution, stand in need of no such instructions as are in my power to impart: but it seemed expedient to prepare an Essay, comprised within moderate limits, which might furnish scientific instruction for the many young men of ardour and enterprise who have of late years devoted themselves to the interesting and important profession, of whose members that Institution is principally constituted. My first design was to compose a paper which might be read at one or two of the meetings of that Society; but, as often happens in such cases, the embryo thought has grown, during meditation, from an essay to a book: and what was first meant to be a very compendious selection of principles and rules, has, in its execution, assumed the appearance of a systematic analysis of principles, theorems, rules, and tables.<br><br>Indeed, the circumstances in which the inhabitants of this country are now placed, with regard to the love and acquisition of knowledge, impelled me, almost unconsciously, to such an extension of my original plan, as sprung from a desire to contribute to the instruction of that numerous class, the practical mechanics of this country. Besides the early disadvantages under which many of them have laboured, there is another which results from the activity of their pursuits. Unable, therefore, to go through the details of an extensive systematic course, they must, for the most part, be satisfied with imperfect views of theories and principles, and take much upon trust: an evil, however, which the establishment of Societies, and the composition of treatises, with an express view to their benefit, will probably soon diminish.
The present work, which is a translation of the Leçons élémentaires sur les mathematiques of Joseph Louis Lagrange, the greatest of modern analysts, and which is to be found in Volume VII. of the new edition of his collected works, consists of a series of lectures delivered in the year 1795 at the Ecole Normale, - an institution which was the direct outcome of the French Revolution and which gave the first impulse to modern practical ideals of education. With Lagrange, at this institution, were associated, as professors of mathematics, Monge and Laplace, and we owe to the same historical event the final form of the famous Géométrie descriptive, as well as a second course of lectures on arithmetic and algebra, introductory to these of Lagrange, by Laplace.<br><br>With the exception of a German translation by Niedermüller (Leipsic, 1880), the lectures of Lagrange have never been published in separate form; originally they appeared in a fragmentary shape in the Séances des Ecoles Normales, as they had been reported by the stenographers, and were subsequently reprinted in the journal of the Polytechnic School. From references in them to subjects afterwards to be treated it is to be inferred that a fuller development of higher algebra was intended, - an intention which the brief existence of the Ecole Normale defeated. With very few exceptions, we have left the expositions in their historical form, having only referred in an Appendix to a point in the early history of algebra.<br><br>The originality, elegance, and symmetrical character of these lectures have been pointed out by DeMorgan, and notably by Dühring, who places them in the front rank of elementary expositions, as an exemplar of their kind.
There is a large class of pupils whose limited time renders it impossible for them to pursue an extended mathematical course. The author, in accordance with his original intention to prepare a series of text-books in Arithmetic, has now endeavored to adapt this work to the wants of this class of pupils. With this purpose in view, the simple, elementary, practical principles of the science are more fully presented than in his larger work, while the more intricate and less important parts have been treated more briefly or entirely omitted. A corresponding change in the character of the examples has also been made. As in the larger work, so here, constant attention has been paid to the brevity, simplicity, perspicuity, and accuracy of expression; and no effort has been spared in the endeavor to render the mechanical execution appropriate and attractive. Definitions, tables, and explanations of signs have been distributed through the book where their aid is needed, to enable the pupil to learn them more readily than when they are presented collectively. Nearly all the examples have been prepared for this book, and are different from those of the larger work; still, to secure uniformity of language (a matter of great importance, as every experienced teacher knows), the leading examples in the several subjects, the definitions and rules, with few exceptions, have been intentionally retained with but little modification.
Until recently upper elementary and high school work in mathematics was planned for the pupil who was expected to continue it in the university. Although logical, its arrangement was neither psychological nor pedagogical. Some progress, however, has been made recently in adapting the study to the needs and abilities of pupils. In the junior high and intermediate school, work in mathematics in the seventh, eighth, and ninth grad should be complete in itself and at the same time preparatory to senior high school work. No effort should be made to finish arithmetic in the eighth grade and algebra in the ninth, while denying the child the interest and beauty that lie in geometry and trigonometry until his taste for mathematics has been destroyed. Nor will alternate bits of formal algebra, geometry, and trigonometry solve the problem. The result is a mastery of none and a confusion in all. Experience has proved that the necessary elements of arithmetic can be taught and certain definite skill developed in the first six grades. In the seventh grade business applications of arithmetic with the simplest elements of bookkeeping should be given.
The opening of a new century seems a fitting time to bring this treatise fully up to the best practice in the teaching of arithmetic. The only material changes needed in the arithmetic proper are the addition of a review of percentage by fraction processes and a fuller treatment of proportional parts. The New Complete Arithmetic contains an unusual number and variety of practical problems. To obtain the data for these problems, the author has gone to science and industry, and to business men for present business usages. It has been his aim to eliminate all obsolete terms and subjects, and to present, as far as practicable, current values. Special attention is called to the treatment of the Metric System, in which formal tables are omitted, and the metric denominations presented on the decimal scale. The characteristics that have given this Series of Arithmetics wide and successful use are:1. A special adaptation in matter and method to the grades of pupils for which each book is designed.2. A practical union of oral and written exercises in a natural system of instruction.
To intelligently perform his work, an artizan must have a knowledge of Elementary Mathematics. When he comes to appreciate this fact for himself the workman generally finds that even the arithmetic he learnt at school has left him, and that he remembers little more than four simple rules and the multiplication table. Teachers soon discover that though anxious to learn, a student of this kind does not wish to lose contact with the practical requirements of the workshop, - he is impatient of "pure" mathematics, - so the question arises how to teach him mathematics enough, by dealing with the calculations themselves which he is actually called upon to make at his work.<br><br>The plan which is found most successful is a compromise. It is useless to say that all students ought to learn the broad principles of mathematics first, and apply them afterwards. Experience has proved that most artizans will not attend classes where the authorities decide that this is the only course.<br><br>To meet the difficulty classes in Workshop Arithmetic, Workshop Calculations and Practical Mathematics, have grown up, and it is to provide for young workmen beginning to attend one of these classes that this little book has been prepared.
In an experience of more than ten years in teaching machine-shop work to evening classes of men and boys actually engaged in the trade, the author has observed a decided lack of mathematical knowledge among ordinary mechanics. Many leave school from the grammar grades. Any mathematical training that they once may have received is, therefore, so far behind them by the time they are well started in their trade that it has practically been forgotten. About all that has been retained is a fair understanding of addition, subtraction, multiplication and division. For such, the natural starting point for a further knowledge of mathematics is the study of fractions.<br><br>Beginning with fractions, this book aims to give, in elementary form, an explanation of the calculations most frequently occurring in machine-shop work. The treatment has been made as simple as possible, in some places almost too simple, perhaps, with the desire to put the explanation in such a form as to be easily understood.<br><br>Many mechanics are mistakenly impressed with the extent of their mathematical knowledge. If they are able to take some formula from a handbook and apply it by rule of thumb to a particular calculation they are called upon to make, they are entirely satisfied.
A work of this kind, on the Mathematical Theory of the Stationary, Marine, and Locomotive Engines, has long been a desideratum; not only as an introduction to Tredgold's large and important work on the same subject, but also for the use of a numerous class of students, who either have not time to read or the means of purchasing the large work just referred to. The author of this "Introduction" has taken great pains to supply this link in the chain of scientific research so much required, as well as to adapt it to the wants of practical men, by giving rules in words at length for their use; also for students who have not yet accustomed themselves to the application of mathematical formula?, by which their progress in studies of this kind will be greatly facilitated, until at length they arrive at full competence in both the theoretical and practical parts of these important subjects, and thus be prepared to understand with ease the various complexities of Tredgold's large and complete work.
Ever since Warren Colburn, following in the footsteps of Pestalozzi, published his Intellectual Arithmetic early in the last century, teachers have recognized the great value of oral work in number. Oral work is furnished in the textbooks in primary arithmetic, and in some cases in books for higher grades. Most text-books used in the last four years of the elementary school, however, need supplementing in this important particular, and this reason prompted the authors to prepare this book.<br><br>The chief principles that have guided the selection and arrangement of material have been as follows: The oral arithmetic needed for practical life relates mainly to the fundamental operations. These operations should, therefore, be reviewed in each school year, the degree of difficulty increasing slightly as the pupil proceeds, but never becoming greater than that encountered in daily business life. Together with the work in abstract number, which Pestalozzi so strongly emphasized, should go a range of applications related to the pupil's interests as they vary from year to year. No particular effort should be made to conform to the sequence of any text-book in written arithmetic, since the prime object of oral arithmetic is continually to review topics that have been passed in the usual sequence of written work. |

Présentation de l'éditeur
Some, at least at first, was a great deal of confusion among teachers, students, and parents. Since then, the negative aspects of "new math" have been eliminated and its positive elements assimilated into classroom instruction. In this charming volume, a noted English mathematician uses humor and anecdote to illuminate the concepts underlying "new math": groups, sets, subsets, topology, Boolean algebra, and more. According to Professor Stewart, an understanding of these concepts offers the best route to grasping the true nature of mathematics, in particular the power, beauty, and utility of pure mathematics. No advanced mathematical background is needed (a smattering of algebra, geometry, and trigonometry is helpful) to follow the author's lucid and thought-provoking discussions of such topics as functions, symmetry, axiomatics, counting, topology, hyperspace, linear algebra, real analysis, probability, computers, applications of modern mathematics, and much more. By the time readers have finished this book, they'll have a much clearer grasp of how modern mathematicians look at figures, functions, and formulas and how a firm grasp of the ideas underlying "new math" leads toward a genuine comprehension of the nature of mathematics itself.
This book is very much in the same spirit as more recent books such as Keith Devlin's "Mathematics, the New Golden Age" (which I also recommend). It explains various subjects in pure mathematics in order to make them accessible and interesting to non-mathematicians. A great variety of subjects are covered, including abstract algebra, group theory, number theory, and especially topology, to which the author devotes several chapters. The links between different branches of mathematics (e.g. topology and group theory) are given special attention, and one of the central themes of the book is the fundamental unity of mathematics. I strongly recommend this book to anyone with a serious interest in mathematics. Plus, the price is definitely right!

This charming book was written by a man who knows how to teach, and how to have fun. For example, as each successive topic is discussed, Mr. Stewart is careful to furnish the reader with an intuitive grasp of its main points. Only then, does he delve into the topic's details. However, what really makes this book readable is the author's wit, and sense of delight, as he illuminates--one-by-one--the abstract concepts of modern mathematics. Amazingly, this book can be read by almost anyone, and they will come away with an understanding of the why, and the wherefore, of modern math. In theory at least, having a degree in pure math meant that I had insights that most engineers don't have. In reality, it meant I was more aware of what I didn't understand. When I got this book, I went straight to the topics I'd never gotten the point of: set theory, topology, and hyperspace. I was not disappointed, but it was not until I settled down and read the whole book that I really got the point. Modern mathematics (modern meaning the late 1800s on) provides a framework for all math. That is why it is--of necessity--more abstract, generalized, and rigorous. Interestingly, the figures in this book are hand drawn. Perhaps its because this book has a way of transporting the reader to a university classroom - somewhere. It wouldn't have seemed right if the figures were anything but hand drawn.

Convincingly demonstrates the interrelationships between different areas of modern mathematics. Great mathematics for the layman without being in the slightest bit condescending. I have had an amateur's interest in mathematics since high school but was never able to follow it up professionally. This book is the best I have read in the 30 years I have had this interest. A delight to read, educational and informative.

This is a serious book. Stewart explains clearly and concisely for a non-mathematician some of the central ideas of mathematics. Perfect for those willing to put in some thought. I'd also recommend it to anyone in first year pure math. And especially to anyone who teaches math.

This book is by far the best book on mathematics I have ever read. It teaches the concepts in an intuitive, exciting way, and yet it is able to remain fun and engaging throughout. Technical material is tackled, in depth, without there seeming to be any work done. There are no exercises to be done, you simply follow Stewart along for a tour through modern mathematics. Ian Stewart's writing is flawless and almost turns this book into a thriller. I read this book in one night- I could not put it down! I stayed up until 4 in the morning reading and rereading passages; it is truly a masterpiece. The chapters are as follows:
Chapter 1- Mathematics in General: Here Stewart describes certain aspects of mathematics, and discusses their purpose and implications. He talks about abstractness and generality, intuition vs. formalism, and pure vs. applied mathematics. He tells the reader the importance of understanding WHY a theorem is true, not simply that it is. He ends with a collection of anecdotes.
Chapter 2- Motion without Motion: This is an example of thinking a bit outside the box. The chapter is devoted to overturning Euclid's proof that the base angles are congruent, and making a new one based on rigid motions. It doesn't sound too engaging, but, somehow, Stewart manages to make it quite exciting!
Chapter 3- Short Cuts in the Higher Arithmetic: A basic introduction to number theory- prime numbers, moduli, congruences, etc. The informal tone makes this the easiest and most understandable read on number theory I've yet encountered.
Chapter 4- The Language of Sets: Throughout the rest of the book, Stewart uses the language of set theory, so he introduces that here in an easy to understand way (using some imagery like bags of items, etc).
Chapter 5- What is a function?: Here Stewart addresses some of the historical problems of defining a function, and then uses the set theory from the previous chapter to define a general function, and the different types of functions.
Chapter 6- The Beginnings of Abstract Algebra: An introduction to groups, fields, rings, etc. Stewart uses the rigid motions from Ch. 2 as an example of the group concept, and then goes on to make a proof about the game solitaire (the British version) using groups. Also an explanation of the proofs about constructibility (trisecting an angle, etc) are given here.
Chapter 7- Symmetry: The Group Concept: This is where we begin to see that Ian Stewart may have a bit of a bias towards abstract algebra and group theory, as that is his specialty. That is perfectly fine, but definitely something to be aware of. The chapter on Real Analysis is certainly less in-depth than this one, but there are many hundreds of books on that you can use to fill the gaps. (Also, Real Analysis is difficult to make accessible to those without a background in calculus, whereas algebrais concepts are fairly natural). In this chapter Stewart discusses groups, subgroups, and isomorphisms with great passion.
Chapter 8- Axiomatics: This is one of my favorite chapters, and it centers on Euclidean geometry and the importance of axiomatics. It discusses models, the parallel postulate, alternate geometries, consistency, and completeness.
Chapter 9- Counting: Finite and Infinite: This is the standard treatment of Cantor and his amazing discovery. I mostly skimmed this chapter, because I had just completed a book specializing in the subject.
Chapter 10- Topology: From Mobius strips, to Klein Bottles, to orientability, to the Hairy Ball Theorem. This chapter keeps to its title. I especially love the last line about the Hairy Ball Theorem (which is a theorem that seems entirely useless at face value). "It has one application in algebra: it can be used to prove that every polynomial equation has solutions in complex numbers (the so-called 'fundamental theorem of algebra')."
Chapter 11- The Power of Indirect Thinking: This is a foray into graph theory and Euler's Formula. A lovely discussion at the end about coloring, as well.
Chapter 12- Topological Invariants: Continues the discussion of topology and proves Euler's generalized formula. Also classifies surfaces, and proves some more coloring theorems.
Chapter 13- Algebraic Topology: You can see that topology is an incredibly important tool in modern mathematics. Here he discusses Holes, Paths, and Loops.
Chapter 14- Into Hyperspace: A short treatment of polytopes and higher dimensions.
Chapter 18- Computers and Their Uses: Programming and how it works on a mathematical level.
Chapter 19- Applications of Modern Mathematics: A very interesting read about optimization and catastrophe theory.
Chapter 20- Foundations: The best treatment of Godel's proof I have yet to see. It is surprisingly rigorous, but easy to follow.
Appendix- And still it moves...: This was added 5 years after the book was written, and is an absolute gem! Stewart addresses the proof of the four-color theorem, he talks about polynomials and primes, he talks about chaos and attractors, and he ends with a reflection on real mathematics. A great end to a masterpiece.
This book is for everyone and anyone- a modest background in high school algebra and an appreciation for mathematics is all you need. Buy this book! Give it to your friends! |

If you are talking about "Introduction to Geometry" by Coxeter and "Geometry Revisited" by Coxeter and Greitzer, the consensus seems to be that both of them are pretty advanced, but "Introduction to Geometry" is significantly more so, while "Geometry Revisited" is closer to something 'right after high school geometry class,' so I guess you should start with the latter (assuming you do have some geometry knowledge already).
Geometry Revisited is much more elementary, aimed at high-school teachers and bright high-school students or college frosh. For example, K. Strubecker wrote in his AMS Math Review
The tenor of the translation of Coxeter's beautiful tome Geometry revisited [Random House, New York, 1967] is in keeping with the objectives of the Klett Textbooks in Mathematics series which are intended to convey to freshmen and teachers of mathematics---via interesting representations---an approach to different aspects of mathematics, especially to geometry, that is kept as concrete as possible and so is applicable in schools. The volume contains six chapters which deal with the following topics: (1) Points and lines connected with a triangle; (2) some properties of circles; (3) collinearity and concurrence; (4) transformations; (5) an introduction to inversive geometry; (6) an introduction to projective geometry; The very lucid presentation takes the reader from elementary problems of plane Euclidean geometry to the fundamental concepts of non-Euclidean geometry, whose metric is briefly illustrated by the conformal model. Starting with simple geometric figures (triangle, lines, circle) and their properties, the volume advances to higher problems and figures in a manner that is convenient for the student and also whets his appetite. The always original developments use very simple tools (theorems of Ceva and Menelaos) and soon proceed to higher configurations (theorems of Pascal and Brianchon on the circle). The conics are obtained from circles as polar figures of the circles. The book is rich in remarkable facts and thereby is very effective in promoting the significance and the value of geometry in mathematical teaching, a promotion which is very necessary in view of today's predominance of set theory, analysis and algebra on the school and university level, and which deserves the skillful hand of distinguished scholars. An advantage in this recruiting endeavor is the high degree of visualizability of geometry, the easy comprehensibility of its problems and interesting theorems, and the challenge emanating from these problems to occupy oneself with their solutions. This purpose is also served by the numerous problems contained in the text whose solutions are listed at the end of the book. Many historical remarks are woven into the text.
Geometry Revisited has a much narrower domain of content than an Introduction to Geometry. If your goal is to get a sense of what different kinds of problems, techniques, and concepts geometry has evolved to deal with, Introduction to Geometry is a "dated" but somewhat comprehensive choice. (For example, the whole "world" of computational geometry came on the scene after Coexeter's book.) One typically does not read mathematics books from cover to cover and one can dabble in Introduction to Geometry to see some of geometry's many parts. If one has heavy sledding in places than looking at the wiki article of the topic causing trouble might help.
I'm currently reading Geometry Revisited and working through the solutions to all the problems on a Quora blog with the help of Geometer's Sketchpad and the hints in the back of the book. High school was a LONG time ago for me, and my progression was to be looking for a good next step following reading Euclid's Elements. For me, G-R is great. One of its attributes is to look at modern (i.e. post ancient Greece) results in Euclidean geometry.
I love the style of the book, forcing you to think but giving you everything you need to fill in the gaps, and always doing so succinctly and gracefully. I think you do need to know some of the core propositions in Euclid (or be prepared to look them up), but not a great deal more. I agree with what others have said: Introduction to Geometry is more advanced. While reading G-R I page through I-T-G as a preview of things to come, but for someone with my background G-R is the better place to start. I highly recommend Geometry Revisited! |

Editorial Reviews
Booknews
Splendid undergraduate text, intended to function as a companion to the distinguished author's Linear algebra and to provide young mathematicians with a secure command of the fundamentals of groups, rings, fields, and related structures. Ten chapters, many excellent problems, written with exemplary clarity and with exceptional sensitivity to what young readers might on first encounter consider to be "scary". Departs from the previous edition (1987) by the inclusion of some new material and exercises. The author has been very well served by the production people at Springer, who have produced a physically beautiful book at a reasonable price. (NW) Annotation c.

From the Publisher
From the reviews of the third edition:
"As is very typical for Professor Lang's self demand and style of publishing, he has tried to both improve and up-date his already well-established text. … Numerous examples and exercises accompany this now already classic primer of modern algebra, which as usual, reflects the author's great individuality just as much as his unrivalled didactic mastery and his care for profound mathematical education at any level. … The present textbook … will remain one of the great standard introductions to the subject for beginners." (Werner Kleinert, Zentralblatt MATH, Vol. 1063 |
Description
An introductory course in problem-solving for vocational and technical programs that use basic computation (both without and with a calculator), pre-algebra, and introductory algebra and geometry skills. Course includes guided and independent practical problem solving, contextualized small-group classroom activities and open-ended projects. A prescribed problem-solving structure will be followed. Prerequisite: Appropriate placement score.
Intended Learning Outcomes
Apply a prescribed problem-solving structure, which includes: interpreting given information, translating given information into mathematical language, predicting a quantitative outcome, performing the calculations (by hand and with a calculator) using a prescribed methodology, and judging the results.
Develop and organize problem solutions in writing.
Use one or more of the following methodologies to solve applied word problems:
a. Addition, subtraction, multiplication, division, rounding, estimating, and order of operations for whole numbers, signed number, fractions and decimals.
b. Ratios and proportions.
c. Percents (finding an unknown part, base or rate; percent change).
d. Unit conversions within and between English and metric unit systems.
e. Direct measurement calculations, either conceptually or with measuring tools.
f. Choose the appropriate formula and solve for the parimeter, area, and volume of various geometric shapes.
g. Solve for a given variable by rearranging a simple formula. |
Note I said "shouldn't". A high school physics class has little need for numbers. Conceptual questions are more important, and the calculations can be abstract; for example, "A box is at rest on a slope. The coefficient of static friction between the box and the surface is μ. What is the greatest possible angle of inclination?" This sort of question sidesteps the numerics issue, meanwhile better testing understanding than if I had asked for the minimum coefficient of static friction such that a 2kg box would stay at rest on a slope of inclination 37 degrees from horizontal. As well, the first question makes obvious the dependencies of the problem, such as the fact that the answer doesn't depend on the gravitational strength or the weight of the box.
So basically ignoring all of the practical side of physics, which involves actally doing experiments. What you have just described was basically my high school maths mechanics class. Physics is related to maths, but it is not maths, half of it is experimenting and calculating stuff in the real world, all of which can serve to re-enforce the theoretical ideas.
Oh, sorry, I should have been more clear. I'm referring primarily to exams and testing theoretical material. By all means, yes, calculators/computers should be used in experimentation and lab settings. |

About the Author
Leif Mejlbro was educated as a mathematician at the University of Copenhagen, where he wrote his thesis on Linear Partial Differential Operators and Distributions. Shortly after he obtained a position at the Technical University of Denmark, where he remained until his retirement in 2003. He has twice been on leave, first time one year at the Swedish Academy, Stockholm, and second time at the Copenhagen Telephone Company, now part of the Danish Telecommunication Company, in both places doing research.
At the Technical University of Denmark he has during more than three decades given lectures in such various mathematical subjects as Elementary Calculus, Complex Functions Theory, Functional Analysis, Laplace Transform, Special Functions, Probability Theory and Distribution Theory, as well as some courses where Calculus and various Engineering Sciences were merged into a bigger course, where the lecturers had to cooperate in spite of their different background. He has written textbooks to many of the above courses.
His research in Measure Theory and Complex Functions Theory is too advanced to be of interest for more than just a few specialist, so it is not mentioned here. It must, however, be admitted that the philosophy of Measure Theory has deeply in
uenced his thinking also in all the other mathematical topics mentioned above.
After he retired he has been working as a consultant for engineering companies { at the latest for the Femern Belt Consortium, setting up some models for chloride penetration into concrete and giving some easy solution procedures for these models which can be applied straightforward without being an expert in Mathematics. Also, he has written a series of books on some of the topics mentioned above for the publisher Ventus/Bookboon |

CARY, NC (Aug. 08, 2012) – SAS Curriculum Pathways has launched a free Algebra 1 course that provides teachers and students with all the required content to address the Common Core State Standards for Algebra. Available online, the course engages students through real-world examples, images, animations, videos and targeted feedback. Teachers can integrate individual components or use the entire course as the foundation for their Algebra 1 curriculum.
"Success in Algebra 1 opens the door to STEM opportunities in high school and beyond, and can set students on the path to some of the most lucrative careers," said Scott McQuiggan, Director of SAS Curriculum Pathways. "This course gives teachers engaging content to support instruction, and will help them meet Common Core requirements."
SAS developed the Algebra 1 course in collaboration with the North Carolina Virtual Public School, the North Carolina Department of Public Instruction and the Triangle High Five Algebra Readiness Initiative, an organization that promotes the important role mathematics teachers play in preparing students for college and careers.
The course maps to publisher requirements recently established by the lead writers of the Common Core State Standards for Mathematics. More specifically, the course addresses the authors' concerns for greater emphasis on mathematical reasoning, rigor and balance. In addition, the course takes a balanced approach to three elements the writers see as central to course rigor: conceptual understanding, procedural skill, and opportunities to apply key concepts. It incorporates 21st-century themes like global awareness and financial literacy while weaving assessment opportunities throughout the content.
While Algebra 1 is the first full course developed, SAS Curriculum Pathways provides interactive resources in every core subject for grades six through 12 in traditional, virtual and home schools at no cost to all US educators. SAS Curriculum Pathways has registered more than 70,000 teachers and 18,000 schools in the US.
SAS Curriculum Pathways aligns to state and Common Core standards (a framework to prepare students for college and for work, and adopted by 45 states), and engages students with differentiated, quality content that targets higher-order thinking skills. It focuses on topics where doing, seeing and listening provide information and encourage insights in ways conventional methods cannot. SAS Curriculum Pathways features over 200 Interactive Tools, 200 Inquiries (guided investigations, organized around a focus question), 600 Web Lessons and 70 Audio Tutorials.

You have chosen your curriculum and you are all ready to dig in. Right? Nope! All of that great curriculum is useless if you do not have clear and concise plans for how and when you will use it. Organizing all of the resources and materials that create a value added experience for both you and your child or children is like putting a puzzle together. It can be frustrating when your time or space are limited. This can be a challenge for any educator. Often, homeschool parents have far fewer resources with which to plan. But, never fear! Here are a few online resources to assist you with streamlining the planning process.
PlanbookEdu.com offers free lesson plan resources as well as a premium service that allows uploads, Common Core Standards, and much more. As far as value goes, this one was not my absolute favorite, although the interface was nice.
LearnBoost.com is one of my top three online lesson planning tools. It not only allows you to plan your lessons in "the cloud", it is also an online gradebook too. Need to generate some reports or look for trends? It has all of that too! Best of all, it is completely free!
ClassConnect.com is all the rave among tech savvy educators. The interface is easy to navigate and it allows you to link to your Pinterest, Sparkpeople and other accounts too. All accounts begin with 1GB of free storage and there are a couple of ways to get ore without spending a dime. You can share your lesson plans with others as well as get some wonderful, complete, lesson plans from other educators. ClassConnect is my personal favorite
These are just a few suggestions, and new apps, websites, and other resources are popping up everyday. Stay tuned!

Mathematics Placement
Based on your previous coursework and experience in mathematics, you can determine which of the following initial mathematics courses would be most appropriate if you choose to take a Mathematics course to fulfill the Quantitative and Analytical Reasoning requirement. Read the descriptions of these courses carefully, mindful of your prior math preparation, and choose the level that matches your interests and abilities. First-year students typically choose their first mathematics course from among the four options listed below. Several majors require specific quantitative courses as seen in the table on Quantitative and Analytical Reasoning.
Students who are primarily seeking to obtain a broad background and to fulfill the quantitative requirement will be best served by options 1 through 4. Students desiring a more technical quantitative background, particularly for use in mathematics or quantitative science, will be better served by options 4 through 9, courses in the main calculus sequence. Option 4 does indeed fit both categories of students. All of the courses in options 1 to 4 have the (QA) or (QA*) designation as indicated.
If you opt to take calculus, which course in the sequence is for you? Information for placement within the calculus sequence is provided below. Your background and previous calculus experience will place you into the most suitable course. You may also contact a member of the Mathematics Department for advice – see
Statistics (MATH 138) (QA*) - An introduction to descriptive and inferential statistics. Emphasizes everyday applications and practical skills. This course is an excellent preparation for dealing with the statistics one encounters every day in our society, and is particularly recommended for students who neither need nor desire a calculus background. Prerequisite: two years of high school algebra.
Discrete Mathematics (MATH 163) (QA) – An introduction to basic techniques and modes of reasoning in combinatorial problem-solving. Topics will be chosen from combinatorial mathematics, logic and Boolean algebra, difference equations, graph theory and applied algebra. Prerequisite: two years of high school algebra. Note this course is offered only in spring semester.
Modeling with Calculus (MATH 140) (QA*) – Modeling with Calculus introduces and applies the concept of calculus to solve open-ended, real-word problems, especially those in the natural and social sciences. The emphasis is on developing and interpreting mathematical models. Topics include differential calculus, linear algebra, and differential equations. This course takes advantage of computational tools so that the focus can be on calculus concepts useful in applied work. This course is appropriate for students with no prior calculus experience. Prerequisite: High school math beyond Algebra II recommended. Students who have taken a full year of high school calculus should begin calculus study with MATH 152, MATH 153, or MATH 249; see calculus placement advice below.
Accelerated Calculus I (MATH 151) (QA*)(0.5 cr) - A first course in calculus for students with some previous exposure to the subject. Topics covered include limits; continuity; derivatives of algebraic, trigonometric, and exponential functions; implicit differentiation; the Mean Value Theorem; and optimization.
Calculus Placement Advice
In the Advising and Course Preferences Questionnaire you indicated if you have previous calculus experience. This data will assist the Registration Advisor in placing you into the most suitable course based on your background. While each specific situation is different, we generally follow the placement advice outlined below.
Students with no calculus background should take MATH 140 Modeling with Calculus. This course is designed for students who are likely to only take one course in calculus. We recommend that students have high school math beyond Algebra II. Students with some exposure to calculus who are planning to take more than one calculus course should consider taking Accelerated Calculus I MATH 151, a 0.5 credit course.
Preparation for Calculus: In most cases, students who want to take calculus but who have not had calculus before should take MATH 140, which includes significant pre-calculus review. Students who feel they need more review also have the option to sign up for MATH 135 Preparation for Calculus. Please note that MATH 135 does not carry a QA or QA* designation. Please contact a member of the Math Department if you are not sure which course is best for you.

This book provides good instruction for basic techniques used in economics including Lagrange multipliers and Kuhn-Tucker maximization. It is also a good book for linear algebra as it pertains to economics.
My professor had us buy this book for a course, a class using econ and math together. In this book every odd chapter goes over math, the even chapters goes over Econ theory and how to apply math to them. The book was a simple read, but I feel that with supplemental reading from the professor I was able to understand the book's material better. BUT for $10, this book is a great read if you want read how to bridge econ and math.
The quality of the book is awesome, practically new. More importantly it was shipped right away. I'm a state over from California so it got to me in less than 5 days. Don't remember the exact number ~3. That was awesome because this book goes along with my first graduate class. It allowed me to start reading right away. I didn't fall behind in class waiting for it to get to me. Never write reviews, but I want to do this person a solid like they did me. Thank you. |
The second year undergraduate physics course consists of 13 lectures. The combination of vector calculus and wave physics can often be difficult when first encountered. A good way to gain confidence is to apply them in problems. Mathematica is used as the vehicle for the course notes and assignments and is used both as a calculation and visualization tool.

Overview
Topology is one of the most rapidly expanding areas of mathematical thought: while its roots are in geometry and analysis, topology now serves as a powerful tool in almost every sphere of mathematical study. This book is intended as a first text in topology, accessible to readers with at least three semesters of a calculus and analytic geometry sequence.
In addition to superb coverage of the fundamentals of metric spaces, topologies, convergence, compactness, connectedness, homotopy theory, and other essentials, Elementary Topology gives added perspective as the author demonstrates how abstract topological notions developed from classical mathematics. For this second edition, numerous exercises have been added as well as a section dealing with paracompactness and complete regularity. The Appendix on infinite products has been extended to include the general Tychonoff theorem; a proof of the Tychonoff theorem which does not depend on the theory of convergence has also been added in Chapter |
Building on the strength of the first edition, Quantitative Methods for Business and Economics provides a simple introduction to the mathematical and statistical techniques needed in business.

It includes numerous real world applications and many opportunities for student interaction. It is clearly focused on business, management and economics students taking a single module in Quantitative Methods. |
Pre-Algebra II—Semester A
If math just sat still, like a bump on a log, it wouldn't be of much use to anyone. Not even mathematicians would get excited about it—and you should see some of the things they get worked up over. Lucky for everyone, then, that math is full of sound and fury, signifying something awesome.
(Levels of awesome may vary.)
In this Common Core-aligned course, we'll peel back the veil and uncover the mysteries of all the algebra that comes before Algebra. With boatloads of problem sets, readings, and quizzes, we'll cover
rational and irrational numbers
radicals, exponents, and number theory
linear equations and inequalities with one and two variables
transformations of geometric figures
linear functions
P.S. Pre-Algebra II is a two-semester course. You're looking at Semester A, but you can check out Semester B here.
Course Breakdown
Unit 1. Rational and Irrational Numbers
Get ready for the next level of numbers: rational and irrational numbers. Sure, they might be as different as apples and orangutans, but it's good to have some variety. We'll learn how to convert rational numbers into fractions, how to identify those pesky irrationals, and even how to approximate irrational numbers using rationals. We wouldn't suggest approximating apples with orangutans, though; that might get messy.
$add to cartremove
Unit 2. Radicals, Exponents, and Number Theory
If anything proves that good things come in small packages, it's exponents. Well, maybe not always good, but certainly powerful. These tiny little numbers can really pack a punch, so we suggest putting on some headgear. In this unit, we'll learn about the complicated relationship between exponents and radicals, and how one operation always undoes the other. Oh, maybe it isn't that complicated.
$add to cartremove
Unit 3. Equations and Inequalities in One Variable
Equations are the ultimate balancing act. If the two sides don't match up exactly, everything will topple over. With only a little bit of practice, though, we'll be able to juggle, shuffle, and slide numbers around an equation without the slightest wobble. After that, we'll use those same skills to tackle inequalities, the hippie-like cousins to equations. They don't care much about any single value; as long as the answers fall within a certain range, they go with the flow. Pretty groovy, right?
$add to cartremove
Unit 4. Equations and Inequalities in Two Variables
We'll cover how two-variable equations can describe all kinds of relationships—the good, the bad, the ugly, and the math-y. Mostly that last one, if we're being honest.
$add to cartremove
Unit 5. Geometric Transformations
Sorry, numbers and letters, but we need a break from you. Instead, we'll be movin' and groovin' with figures this unit, except for a few tricky definitions and a quick tango with the coordinate plane. Just be careful; some of these shapes have sharp edges. The last thing we want is for you to get a nasty cut mid-disco.
$add to cartremove
Unit 6. Linear Functions
We're going introduce you to functions nice and slow as we go over the basics: learning the definition of a function, seeing how to identify them by sight in tables and graphs, and visualizing them on the coordinate plane. Then we'll zoom in on linear function and all of their different parts and pieces—no dissection necessary (or wanted). Leave that for your science class.
$add to cartremove
Unit 7. Graphing Linear Equations and Inequalities
Just knowing linear equations inside and out isn't enough: we also have to know how to graph them. Lucky for us, then, that their graphs have a purpose other than looking cool. They can make problems easier to understand and solve—especially when there are real-world applications lurking in the wings. Obviously, looking cool doesn't hurt, either. |

Overview
This handbook is a simplified math reference source and self-study guide for students in economics and business. It supplements standard economics and business texts for college students, both undergraduate and graduate.
Preface
PREFACE
This handbook is designed to correct identified weaknesses in the mathematical and analytical ability of both undergraduate and graduate students of economics and business. The author's goal is to equip students (particularly those with inadequate math preparation) with the basic math concepts and skills needed for modern economic analysis and business decision making in an increasingly quantitative and computer-analytic business environment.
Deficiencies in basic high school math concepts (in arithmetic, algebra, and geometry) hamper students' ability to understand key economic and business concepts like elasticity, graphs, slopes (or marginal values, or relative changes), financial analysis, and the optimization (maximization or minimization) of economic and business objective functions. Standard textbooks in economics, business and college math assume prior knowledge of most of these basic math concepts.
Aptitude tests measure verbal and math or quantitative skills needed for college that students are supposed to have internalized. But many colleges often admit students with weak math backgrounds. Remedial math courses for such students often focus on general math concepts and do not necessarily relate these concepts specifically to pertinent economic and business problems. Further, because some entering graduate students may have worked for long periods of time in fields making little or no use of math, they forget most of the basic concepts.
All the above reasons led to this handbook, which serves as a simplified quick reference source and self-study guide for students to supplement standard textbooks in economics and business which presuppose full grasp of basic math concepts and hence devote little or no time to explaining them. Further, researchers, analysts, businessmen, policymakers, and administrators may also gain from a handbook written in a very simplified and summary format for the average less-mathematically inclined reader.
Some characteristics of this handbook need explanation. First, the general approach is to do away with unnecessary mathematical proofs, formulas, terms and symbols that may confuse the reader. Important symbols and concepts are explained with highly simplified examples to facilitate understanding.
Second, the basic rules and operations of arithmetic, algebra, and geometry are concisely presented, followed by the relevant economic and business concepts and the associated math concepts used. The emphasis is on economic and business relevance of the math concepts.
Third, key formulas and graphs are given with worked examples and a few self-practice questions to help readers understand the concepts.
Finally, notes are provided after each formula or concept is introduced to stress extra important points.
There are eight chapters and six appendices. The first chapter deals with basic arithmetic concepts like the number system, fractions, decimals, percentages, exponents, roots, logarithms and inequalities.
Basic algebra concepts like variables, constants, parameters, symbols, equations, functions and examples of common economic / business functions are presented in chapter 2. Further, chapter 3 deals with graphs of economic / business functions and the slopes of lines (or relative changes of variables, or marginal analysis).
In chapter 4, the basic rules of differential calculus are used to find the slopes (or marginal values) of nonlinear economic and business functions which may have maximum and minimum turning points. The concept of elasticity and the basics of integral calculus are also presented.
Chapter 5 encompasses further topics in algebra like set theory, simultaneous equations, theory of the quadratic function, direct and inverse variation, and their common applications to economics and business.
Miscellaneous topics like math for finance, arithmetic and geometric progressions, index numbers, and real and nominal economic / business variables are highlighted in chapter 6. Basic probability and economic / business statistics are covered in chapter 7, while the fundamentals of matrix algebra are explained in chapter 8.
Unit analysis is briefly explained in appendix A; elementary multiplier analysis and equilibrium national income determination are summarized in appendix B; basic quantitative tools for management decisions are the focus of appendix C; a brief summary of some basic geometrical formulas and facts is given in appendix D; while selected review questions and math tables appear in appendices E and F, respectively.

More About
This Textbook
Overview
This excellent textbook introduces the basics of number theory, incorporating the language of abstract algebra. A knowledge of such algebraic concepts as group, ring, field, and domain is not assumed, however; all terms are defined and examples are given — making the book self-contained in this respect.
The author begins with an introductory chapter on number theory and its early history. Subsequent chapters deal with unique factorization and the GCD, quadratic residues, number-theoretic functions and the distribution of primes, sums of squares, quadratic equations and quadratic fields, diophantine approximation, and more. Included are discussions of topics not always found in introductory texts: factorization and primality of large integers, p-adic numbers, algebraic number fields, Brun's theorem on twin primes, and the transcendence of e, to mention a few.
Readers will find a substantial number of well-chosen problems, along with many notes and bibliographical references selected for readability and relevance. Five helpful appendixes — containing such study aids as a factor table, computer-plotted graphs, a table of indices, the Greek alphabet, and a list of symbols — and a bibliography round out this well-written text, which is directed toward undergraduate majors and beginning graduate students in mathematics. No post-calculus prerequisite is assumed. 1977 2000
Lord of the Rings Modulo Z
LeVeque covers certain topics in great detail, and others can be quite vague. One must have prior knowledge on modular aritmetic in order to get started with this text. The Euclidean Algorithm is explained from origins to applicability in nearly every single proof. LeVeque's best feature is in descripitons of Rings in modulus Z and their respecive domains and their respective theorems, congruences, etc. If you are weak in this area I recommend this text for that area of Number Theory.

Description
Well paying careers demand skills like problem solving, reasoning, decision making, and applying solid strategies etc. and Algebra provides you with a wonderful grounding in those skills - not to mention that it can prepare you for a wide range of opportunities.
This is a COMPLETE Pre-Algebra guide to well over 325 rules, definitions and examples, including number line, integers, rational numbers, scientific notation, median, like terms, equations, Pythagorean theorem and much more!
Our guide will take you step-by-step through the basic building blocks of Algebra giving you a solid foundation for further studies in our easy-to-follow and proven format!
Algebra is a very unique discipline. It is very abstract. The abstractness of algebra causes the brain to think in totally new patterns. That thinking process causes the brain to work, much like a muscle. The more that muscle works out, the better it performs on OTHER tasks. In simple terms, algebra builds a better brain! Believe it or not algebra is much easier to learn than many of us think and this guide helps make it easier!
Like all our 'phoneflips', this lightweight application has NO ads, never needs an internet connection and wont take up much space on your phone!

0030728789: A First Course, Third Edition
This comprehensive text suitable for math, science, and engineering majors, treats standard elementary topics such as undetermined coefficients, systems of differential equations, substitutions and chemical reactions. Students benefit from the conceptual approach, motivated by detailed physical and mathematical examples. Previous exposure to linear algebra or vectors is not assumed: all necessary linear algebra techniques are introduces as needed with respect to systems of differential equations. Early and consistent notation emphasizes the characteristic polynomial, suggests shortcuts such as the exponential shift, and leads to a natural, unified understanding of undetermined coefficients. Expanded treatment of the qualitative theory of linear systems, especially as applied to nonlinear systems, includes new sections on Interacting Populations, Constants of Motion, Lyapunov Functions, and Limit Cycles and Chaos. BASIC computer programs on approximation algorithms illustrate the use of technology in numerical methods |
