I wanted to see how difficult it would be to use the OpenMaple API from a C# program.  It turns out that it is pretty easy to access C .dlls from C#.  I was able to reproduce a commandline equivalent (minus the command history and editing features). 

The source code can be found here: openmaple.cs

I have installed maple12 on a 32-bit computer and now realized that it is too weak. I would like to reinstall it on a much more powerfull 64-bit computer.

I already activated maple12 for that 32-bit computer.

How can I do that?

Thanks for any help.

Studying the integral bug discussed in Axel Vogt's blog, I met the following,

residue(arctan(z)^2/(1+z^2),z=I);

                                 1/2      1/2 2
                                2    (z I)
                       1/2 I ln(-------------)
                                      2

Not talking whether the residue has sense in this case, or not, having z in the answer is very wrong.

I was recently forwarded a link to this Snopes article.

According to the urban legend described therein, text is still readable if all the letters in a word apart from the first and last are randomized. I quickly threw together a Maple worksheet, primarily using its flexible string manipulation tools.

  restart; Digits:=14;     # using Maple 12.02
  J:=Int(arctan(z)^2/(1+4*z^2),z=0..infinity);


  evalf(J);
                           0.40325004753375

  value(J); evalf(%); Re(%);

                ...

Following the midi crash course written by Daniel White, and using a table of midi note numbers, it is rather easy to write a Maple procedure producing midi files. Here is an example that I posted in Simple Sounds thread, slightly modified by adding an instrument as a 3rd parameter:

Does Maplesoft provide Maple help menu online?

Does anyone know what happend to the version of Maple that would run on a Casio PDA? Is it still possible to obtain this software, and is there any PDA that will actually run it?

Go to http://www.facebook.com/pages/Maplesoft/47238276041. Maplesoft on Facebook? Math talk mingling with my meaningless personal status reports? Are we now laying a clear path for the Maple world to walk right into our private lives? Now I’m worried.

Bonjour,
Je travaille avec mapple et je me suis retrouvé face à un probleme.
J'ai une procedure s'appelenant myproc je veux résoudre l'equation suivante myproc(x)=1,ça me cause des probleme que je n'ai pas su resoudre.
En effet, "myproc" contient une procedure if.
Je dois donc faire solve('myproc'(x),x),ça me genere des solution de la forme, RootOf (n*myproc(_Z)) que je n'ai pas su évaluer.
De l'aide.

Let f(y,θ)=y ∗ exp(−y) ∗ cos(k ∗ y ∗ cos θ). The double integrale, first over θ, from 0 to π, and then over y, from 0 to infinity, is equal to π / (1 + k^2)^(3/2) (see, Gradshteyn and Ryzhik, 6.623.2).

Maple is doing well, already in version 7 (my very first verison). You can check this by issuing the following commads
f:= cos(k ∗ y ∗ cos θ)/Pi :
i1 := int(f , θ = 0..Pi) :
i2 := int(y ∗ exp(−y) ∗ i1, y = 0..infinity) ;

Hi:

 

I purchased Maple 12 after talking to a sales rep and was given download link and a temporarary purchase code I could use to activate Maple 12. What is the next step? Will I have to obtain some kind of permement activation? and how can I do this? Thanks!

I am attempting to install Maple 12 on OSX 10.5.6 and have installed X11. When I open the installer it asks for my admin password, I enter it, and then the installer just closes. I am not sure why. Does anyone know why or have possible reasons why? I would love to get this fixed ASAP. Thanks

It is some time ago, that I was fighting with that model and how
to estimate the 3 parameters (until recognizing that one may want
restrictions for them).
Essentially one uses the statistics of the underlying data to get
a reasonable starting guess. 
For an estimation then one can use the Optimization package.
The gradients involved are best coded as a floating point library,
which here is done through a DLL (it should work on all Windows OS),
code in C is included for that.
Meanwhile all can be done using 'Compiler:-compile' or the Watcom
compiler delivered with Maple.
I left that older sheet as it is - in Maple 9 (may be one should
brush it up for concurrent Maple versions, they are grumbling a bit
about the code) and hope it is of interest despite of that.
