  • I would like to be able to read Maple manuals and the AEM book that I have bought on the ipad. I can understand that I will not be able to run the commands. But it woud be nice to read through the different sections while reclining on my bed. Hope that you will make it possible.


    On several occasions, while working with lists or Matrices, I have been drawn to using a combination of seq and if, as in the following:

    seq(`if`(a,b,c), i = 1 .. 10 )

    This appears to be a powerful approach. Unfortunately, I have not found much documentation on it.

    I have been able to pattern-guess to a limited extent for my limited needs.

    Would you know of a good place to go for information?

    My understanding is: "a" is the conditional...

    I have found very little help about the Generate command of the RandomTools package.

    I also have minor gripes about the syntax. And what better way to deal with these than to voice them?

    This is how I was able to generate random lists and random Matrices.

    A list of 10 random integers between 1 and 100:

    L := RandomTools:-Generate(list(integer(range=1..100),10));

          L := [47, 8, 46, 44, 9, 77, 59, 16, 1, 70]

     

    As many of you know now the MRB constant = sum((-1)^n*(n^(1/n)-1),n=1..infinity).

    Here are some equations involving various forms of that summation.

    The first one involves convergent series and is too obvious. The others involve divergent series.

    The last two, however, are new!

     

    Let c=MRB constant and a, c~, x, and y = any number.

     

    sum((-1)^n*(c~*n^(1/n)-c~),n=1..infinity)= c*c~.

    evalf(sum((-1)^n*(n^(1/n)-a),n=1..infinity)) gives c-1/2*(1-a).

    evalf(sum((-1)^n*(x*n^(1/n)+y*n),n=1..infinity)) gives (c-1/2)*x-1/4*y.

    And it appears that

    evalf(sum((-1)^n*(x*n^(1/n)-a),n=1..infinity)) gives (c - 1/2)*x + 1/2*a.

    Dear friends,

    I was working on the integral of cosh(ax)/cosh(x) from zero to infinity with "a" being a rational number p/q where p<q and p-q being odd. I was quite shocked to discover that Maple 15 (X86 64 LINUX)cannot do this integral while Mathematica gets it right every time. I certainly hope this will be rectified soon.

    For those who might be interested the calculation of the integral

    The Maple IDE project team is pleased to announce the release of the standalone version of the Maple programming toolkit. Now Maple IDE is available for Windows, Unix and Mac OS as standalone tool.

    For the information about new versions, please see Maple IDE page.

    For the complete installation instructions see the following video:

    Just happen to come accross this wikiVS page of Maple vs Mathematica. 
    http://www.wikivs.com/wiki/Maple_vs_Mathematica

    I find it heavily biased towards Mathematica. 

    A lot of spam coming in is from the same users.  It seems automated.  These are some repeating offenders

    We have just released Teaching Calculus with Maple: A Complete Kit.  Leveraging both Maple and Maple T.A., Teaching Calculus with Maple includes lecture notes, student worksheets, Maple demonstrations, Maple T.A. homework, and more – everything you need to teach Calculus 1 and Calculus 2.  Teaching Calculus with Maple  was developed at the University of Guelph under the leadership of an award-winning teacher and field-tested in classes with hundreds of students.

    As usual I am going to use this blog post to complain!
    How can anyone in their right state of mind create a Finance Package
    with out procedures for return calulation ie first difference, percentage change, log returns etc

    restart;

    The version 16 of Maple does not know the function "pow", it is replaced by "power". Nevertheless, the codegen[optimize] procedure still generates it!  Moreower, it's not optimal even to write poser(..., 1/2)  as, most probably, the function sqrt must run faster. 

      Here's an example: (the function being optimized just contains some nested square roots)

    > iang10 := [codegen[optimize](Re(int11), tryhard)];
    [ 2 t17

    I want to Play with math full-time.  I posted a help me do it page on my website at marvinrayburns.com under the link titled "Help!" Any ideas on how I can gel it to go viral and maybe get some support from it?

    We have just released a free collection of Maple and MapleSim classroom materials that helps bring modern technology to any introductory course in control design. This collection includes interactive classroom demonstrations that illustrate key concepts; lab projects and assignment questions; and example models ready to be explored.  It’s been designed primarily for instructors, but students should find much of it useful, too.
