Pacman using GeoGebra??!!
Here's how I did it:
1. Go to GeoGebra.
2. Make an angle with given size.
3. A popup will show. Type 324 in the box. Then, an angle wil appear.
4. Put a point.
5. Play pacman! Right click the angle.
It is like chasing, right?

hi BarandaMan
x by 5
Add 2z
take 6
divide by 2
I suspect you ran into difficulty because of this
take 2
divide by -2
when you multiply or divide by a negative amount you must reverse the inequality sign
If you want to explore this rule some more, post back.

CMS Winter 2007 Meeting
We will discuss the structure of hyperelliptic Hodge integrals (integrals of l and y classes on the hyperelliptic locus of curves). We start by giving a purely combinatorial proof of
Faber-Pandharipande's well known formula for l[g] l[g-1], and proceed from there to describe several nice... | {"url":"http://cms.math.ca/Events/winter07/abs/ca.html","timestamp":"2014-04-16T04:14:16Z","content_type":null,"content_length":"19033","record_id":"<urn:uuid:436d0c1b-4100-498a-b7ed-c820b7d2ab3b>","cc-path":"CC-MAIN-2014-15/segments/1397609538110.1/warc/CC-MAIN-20140416005218-00568-ip-10-147-4-33.ec2.internal.warc.gz"... |

Why did the mathematician name his dog Cauchy? Because he left a residue at every pole!
But could the mathematician find the poles and their residues for a given function? He certainly could, with the help of Wolfram|Alpha.

Computability and the Limits of Human Knowledge

generalised pigeonhole principle
December 28th 2009, 04:03 AM #1
Nov 2009
The generalised pigeonhole principle is proved by using contradiction. The proof is given below.
consider there are no pigeonholes that contain more than ceil(m/n) - 1.
Then the total number of pigeons m <= n * ceil(m/n)-1
