Revision Note:I have updated the graph in the attached Maple document based on Doug Meade's comment below.CarTalkPuzzler_9-22-.mw

Car Talk, a humorous phone-in program in which Tom and Ray Magliozzi (Click and Clack, the Tappet Brothers) diagnose and offer solutions for mysterious auto-related maladies, is carried by National Public Radio...

Maplesoft has these interesting bits of Math on their website. For example this one here

http://www.maplesoft.com/mathmatters/airplanes.aspx

It is all nice and all but I would like to see some reference examples to maple for each one, a cool application worksheet that portrays each one nicely.

Using the example link above I searched maplesoft application center for navier stokes...

Dr. Gilbert Lai is a mentor for the FIRST Robotics team SWAT 771. He is helping an all girls team from grades 7-12 design a basketball-shooting robot for this year’s annual FIRST Robotics Competition. Dr. Lai is using MapleSim and Maple to help the team understand the principles involved and design their robot. This blog post is part of a series that chronicles the progress of the team. Posts in the series include:

This is for Spanish speakers only. Not related to Maple, but related to Math. The Spanish newspaper El Pais has a series of videos on various math problems, together with solutions (posted later), it's set up as a sort of competition but just watching is (usually) great fun. You can access the full archive online.

You probably don't need to know much Spanish to follow the problems. Much is illustrated in writing on a black or white board. If you don't speak any Spanish...

I will use this post for a list of conclusions drawn from MRB constant N and the many similar approximations that I have found.

Let x= MRB Constant. Each approximation is followed by a maple input so you can verify these approximations.

A while back, someone asked me for a good way to plot a Klein Bottle in Maple. I didn't have a good answer at the time, but I recently stumbled upon the following, which does a pretty good job if you don't mind the use of Heaviside in the parameterization.

plot3d( [4*(1-1/2*cos(u))*sin(v), 6*cos(u)*(1+sin(u))+4*(1-1/2*cos(u))*(cos(u)*(1-Heaviside(u-Pi))+Heaviside(u-Pi))*cos(v+Pi*Heaviside(u-Pi)),

While reviewing code the other day, I came across the following snippet (here converted to a procedure).

Ds := proc(V::set, n::posint, t)local i,v; {seq(seq((D@@i)(v)(t), i=1..n), v in V)};end proc:

The purpose of this is to generate a set of derivatives at a point of a set of unassigned names. For example

Ds({x,y},2,0); ...

Here is a challenge: reproduce this Mathematica notebook in Maple - without cheating, naturally.

I think I'm jealous. But I'd love to be shown wrong and have someone do up a Maple 14 document which does everything that that notebook does, only better.
