MaplePrimes Announcement

We’ve been busy! We have just released the 2021.2 updates for Maple, Maple Flow, and MapleSim. Here’s a quick overview. These updates are freely available to all customers who have the 2021 version of these products.

Maple

The Maple update includes a variety of corrections and improvements to the math engine and interface. It is available through Tools>Check for Updates in Maple, and is also available from the Maple 2021 download page, where you can also find more details.

In particular, this update includes fixes to the bug in the combine command when working with double summations, and the problems when performing context menu operations on values with units while in Document mode, both of which were reported on MaplePrimes. As always, we appreciate the feedback!

Maple Flow

The Maple Flow 2021.2 update offers a richer range of formatting features for creating professional-looking engineering documents, which have been requested by customers. Highlights include sections, controlling the display of commands, annotating images, and disabling automatic evaluation while making a series of changes.  This update is available from the Maple Flow 2021.2 download page, which also contains more details.

MapleSim

Lots of good stuff here that makes it easier to build and analyze models, including productivity features that speed up the creation of models that use hydraulics, support for the latest CAD file formats in the MapleSim CAD toolbox, the ability to model drift conditions with the MapleSim Tire Library, tools for simulating 3-D winding effects with the MapleSim Ropes and Pulleys Library, and a new MapleSim Web Handling Library add-on (which, I am sad to say, has nothing to do with Spiderman). See What’s New in MapleSim for details, and the MapleSim 2021.2 download page for instruction on how to obtain your update.

December and Maple 2021.2 have both arrived, which means that we can look forward to year 2022 and Maple 2022.

        What should we like to find new in Maple 2022?  Here follow a few suggestions, to which readers of Maple Primes can add.

        In my opinion the weakest feature of Maple 2021 is the solution of integral equations.  Even when this package was first introduced into Maple, a couple of decades ago, it was weak, applicable to only linear such equations.  A quarter century earlier, David Stoutemyer (a true genius and entrepreneur, originator of Mu-Math, Mu-Lisp, Derive and computer-algebra capabilities incorporated in calculators of Texas Instruments) had published code for non-linear integral equations, based on Reduce.  There is a Handbook of Integral Equations by Polyanin and Manzhirov that lists about 2000 solutions of integral equations.  Let Maple 2022 be the basis of a boast by Maplesoft for Maple to be able to solve 96 per cent of those equations, in the same way that Edgardo Cheb-Terrab can (rightfully) boast that Maple can solve 96 per cent of differential equations in a standard compilation.  Any differential equation can, apparently, be converted to an integral equation, whereas the converse is not true.  For this reason alone, the development of solution of integral equations should become a priority to assist users of Maple.

        Another area worthy of expansion and enhancement is the solution of differential equations in terms of Heun functions; that capability is already present, but working with those functions in their present form is difficult and slow.  The inclusion of related functions, such as Lame functions, into Maple is long overdue.  Although efforts have been devoted to the development of the physics package in recent years, culminating in a tremendous achievement of capability, only a few physicists in the world can appreciate that luxury, whereas the solution of differential, and integral, equations permeates all science and engineering. 

          What items are on your list of wishes for Maple 2022?

Some years ago I taught a calculus course for especially talented students. I made up the following problem as an interesting challenge.

Take a circular disk made of paper. Cut out a sector of some angle α from the disk. Roll each of the resulting two pieces into cones. Let V(α) be the sum of the volumes of the two cones. Find the α that maximizes V(α).

Here is an animated statement of the problem, produced in Maple.
