Russian content for Maple T.A.

Tests are learning, not just inspectors.

I saw a fun blog post today from someone who plotted the Batman symbol within Maple. Enjoy!

All 19 chapters updated Mapler in elementary mathematics will be posted on this site:

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

Since the collection began

A collection from 20 problems for students.
12 variants for each problem.
Adequate solution.
Programs are built into the buttons.
Kit has been used successfully for 12 years.

SHA-0.3.zip includes a Maple archive and help data base that implement the SHA algorithm (SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512).  The implementation is interpreted Maple, so will be considerably slower than a compiled routine, but these should be fast enough for likely uses in Maple.  For example

CodeTools:-Usage(SHA("The quick brown fox jumps over the lazy dog", 512));
memory used=502.00KiB,...

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.

A worksheet that plots Tupper's Self Referential Formula

The complexplot3d command can color by using (complex) argument for the hue, and compute height z by magnitude. So, when rotated to view the x-y plane straight on, it can provide a nice coloring of the argument of whatever complex-valued expression is being plotted.

Another way to obtain a similar plot is to use densityplot (with appropriate values for its scaletorange option) and apply argument to the expression or function being plotted. For some kinds of complex-valued...

The June edition of the IBM Ponder This website poses the following puzzle:

Assume that cars have a length of two units and that they are parked along the circumference of a circle whose length is 100 units, which is marked as 100 segments, each one exactly one unit long.

A car can park on any two adjacent free segments (i.e., it does not need any extra maneuvering space).

The problem

Back in 1996 I was working for the Symbolic Computation Group at the University of Waterloo, developing algorithms and code...

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.

Sleep Sort is a hilarious (to me anyway) joke dressed up as a sorting algorithm.

Here it is in non-obfuscated (if somewhat garbagey) Maple code (need version 15 since it uses ?Threads,Sleep )

SleepSort := proc(L::list(posint),$)
local Lout, p, i;
    Lout := NULL;

    p := proc(n::posint,$)
        Threads:-Sleep(n);
        Lout := Lout, n;
    end proc:

    Threads:-Wait( seq( Threads:-Create( p(i...
