Cramers Rule
Cramer's Rule
The method of solution of linear equations by determinants is called Cramer's Rule. This rule for linear equations in 3 unknowns is a method of solving -by determinants- the following equations for x
, y, z
a[1]x + b[1]y + c[1]z = d[1]
a[2]x + b[2]y + c[2]z = d[2]

A police car stopped at a set of lights has a speeder pass it at 100 km/h. If the police car can accelerate at 3.6 m/s2, a) how long does it take to catch the speeder? b) how far would the police car
have to go before it catches the speeder? c) what would its speed be when i... | {"url":"http://www.jiskha.com/members/profile/posts.cgi?name=alex","timestamp":"2014-04-21T11:19:44Z","content_type":null,"content_length":"28393","record_id":"<urn:uuid:b887a5fc-55d8-49a6-b0c7-81a06549d43a>","cc-path":"CC-MAIN-2014-15/segments/1397609539705.42/warc/CC-MAIN-20140416005219-00259-ip-10-147-4-33.ec2.inter... |
Yahtzee Fun
lol That's what I'm trying to figure out. I was told that there's another way, but don't know how to figure it out.
Hmm. Is it possible they meant another way to do it besides using transition probability matrices? For instance, you could do it recursively. But I think it's easier to do it your way, with ma... | {"url":"http://www.physicsforums.com/showthread.php?p=2666890","timestamp":"2014-04-18T21:32:48Z","content_type":null,"content_length":"29689","record_id":"<urn:uuid:5a60ebe9-5e16-46ee-9c34-7f802368c5ee>","cc-path":"CC-MAIN-2014-15/segments/1397609535095.9/warc/CC-MAIN-20140416005215-00419-ip-10-147-4-33.ec2.internal.w... |
RISPs: Rich Starting Points
Ahhh, I like
. I think they'll be a good addition to my practice, mainly in pre-calc, which I'll be teaching in the fall.

Finding whether a polynomial exists
Given a set of values how can one determine whether any polynomial (say p) of degree atmost 3 and having real coefficients exists such that $p(i) = x_i$ for all i ?
For the set of values:

Some thoughts on the sensitivity of mixed models to (two types of) outliers
Outliers are a nasty problem for both ANOVA or regression analyses, though at least some folks consider them more of a problem for the latter type of analysis. So, I thought I post some of my
