Fun interactive paradox about the MRB constant.

I was about to post this as a "How-do-I" question, but while composing my question, I stumbled upon the solution.  In case this "discovery" would be useful, I'm posting it here.

For some coursework, I'm developing fitting sinusoids to experimental data (poor-man's Fourier Analysis).  At one point, I do a "brute-force-least-squares" computation, one step of which involves computing the sum of a sine over N equally-spaced intervals around the circle.  This...

I spent this past week preparing a Webex presentation to a client who was interested in using Maple for a physics course in chaos. Of the two texts selected for the course, I had one on my own bookshelf. So I scanned Steven Strogatz' text Nonlinear Dynamics and Chaos (Addison Wesley, 1994) for topics that would profit from investigation with Maple.

A new edition of Maplets for Calculus  (M4C) is now available.  M4C v1.3 is a collection of 129 maplets for calculus students and instructors.  The 35 new maplets fill in some gaps in the coverage of precalculus and single variable calculus and begin to address multivariate topics. Each maplet provides a customized graphical user interface (using 2D and 3D graphics and animation) to provide immediate, step-by-step guidance through an endless supply of random ...

As a user of Maple 13, namely in computations on General Relativity & Tensor Calculus, I would like to let you know I just got, using Maple 13, the WRONG SIGN (positive Riemann scalar curvature in stead of correct NEGATIVE Riemann scalar curvature) in studying a threefold used as a 'Public Space' by Milne many years ago.

The square of the distance on the said threefold is dE^2=dR^2+(c*t0)^2*sinh(R/(c*t0))^2*(dtheta^2+sin(theta)^2*dphi^2) and you might be interested...

Most of the comparisons (that I've seen so far) amongst Maple, Matlab, and Mathematica are either incomplete, inaccurate, or biased.

On Tuesday August 10, 2010, the first meeting of an ad hoc group focused on exploring the use of MapleSim in the engineering curriculum met at McMaster University, Hamilton, Ontario, Canada.  Faculty from McMaster University, Kettering University, Lawrence Technical University, University of Waterloo, Ryerson University, University of Ontario Inst. of Technology, and the State University of New York (Buffalo and Binghamton).

The full-day workshop provided an ideal...

Maple's Statistics package contains many predefined probability distributions; well-known ones such as the normal distribution and lesser-known ones such as the Gumbel distribution. For these distributions, we ship efficient algorithms that can quickly generate a large number of sample points. To generate a sample of size 10⁶ of both of these distributions, and print the time it took to do this (in seconds), you can run the following:

Look at this article (Its loading can take a few minutes: approximately 5 MB.). All those pictures could be created with Maple.

The greatest benefits from bringing Maple into the classroom are realized when the static pedagogy of a printed textbook is enlivened by the interplay of symbolic, graphic, and numeric calculations made possible by technology.  It is not enough merely to compute or check answers with Maple.  To stop after noting that indeed, Maple can compute the correct answer is not a pedagogical breakthrough.

This is a collection of Maple product brochures.  There are some missing, please feel free to add the missing ones to this somewhat historical collection.  I've attached a small visual of the brochures and a link to download the pdf if you wish.  Again please feel free to help me complete this collection.

The ones I am missing are all brochures before Maple 6, Maple 7, Maple 8, and Maple 9.  I will add the most recent ones after Maple 10 later, but I've started this to get things rolling.  I would hope this blog will at some time in the future contain a complete collection, however, with the internet changing, advancing everyday and the need to purge old files, it could be very difficult to source older information... good luck and enjoy.
