Question:

Let say you have a revolver with six chambers. There are two bullets in the gun. The bullets are
located in two chambers next to each other. You now want to play Russian roulette. You spin
the barrel so that you don’t know where the bullets are and then pull the trigger. We assume
that you don’t kill yourself with this first attempt. Now assuming that you want to maximize
the chance of not killing yourself is it...

Russian teachers have met the workshop with enthusiasm. Even during the holidays.
For me, the enthusiasm - it's thousands of visitors.

In 2010-2011, I persuaded tens of thousands of Russian and Ukrainian students and students in that Maple - a very useful thing.
Testimonials - the number of visits and thanks.
So I decided to resurrect some of my old sites.
Not just for history!

The first: Maple PoverTools.

I would like to pay  attention  to the PhD thesis by John Baber in an actual field of complex analysis done with Maple: http://arxiv.org/PS_cache/arxiv/pdf/1106/1106.4737v1.pdf . It should be noticed that the usage of Maple is an essential tool of this work (for example, see p. 28, 43, and around), not a fashion trend.

In a reply to Markiyan Hirnyk's recent question on this topic, Alec Mihailovs posted solutions 
for  n=1..7 for the mean distance between random points in an n-cube.

Answering to that question, I posted several procedures finding minimal polynomials for the elements of finite fields. The best one was the following,

alias(a=RootOf(T^100+T^97+T^96+T^93+T^91+T^89+T^87+T^86+T^82+T^81+T^71+T^70+T^67+T^61+
T^60+T^57+T^54+T^53+T^52+T^49+T^48+T^45+T^44+T^42+T^39+T^36+T^33+T^32+T^31+T^29+T^28+T^27+

F:=GF(2,100,op(a)):
z:=F:-input(2):

MinPolyGF:=proc(x,y:=_X)

A:=Matrix(100,...

In this post I will describe a little about the OU course MS325: Computer Algebra, Chaos and Simulations, which I took last year.

MS325 is a level 3 OU applied mathematics course, which means, roughly that it is pitched at the level of a final year mathematics undergraduate. It is split into three components: Computer Algebra, which teaches the use of Maple and Maple programming; Chaos, which teaches dynamical systems, deterministic chaos and fractals, with an emphasis...
