Today I found that login does not work on MaplePrimes.  I changed my password, but still not.

There is no error, I am just returned to the provious page, still not logged in.

Safari 5.1.2, Mac OS 10.6.8

I had to log in using Firefox to post this!

Here is a simple version of the code:

restart;
plots[textplot]([4,2,q[n]]);
plotsetup(gif,plotoutput=`p.gif`);
plots[textplot]([4,2,q[n]]);
plotsetup(default);

A recent announcement said that downvoting was removed because "many MaplePrimes did not like it".  MaplePrimes?  Is that what are we called?  How about primers?  Or maybe primarians?

I'm using Maple 15.  It seems to me this worked in some previous version...

Consider the Lambert W function, y=LambertW(0,x) ... I want Maple to tell me the asymptotics for it,

something like this:

But I don't get that now.  Is my memory faulty that I got it in the past?

Maple 15:

  asympt(LambertW(0,x),x);

not very useful...

series(LambertW(0,x),x=infinity);

with(MultiSeries):
series(LambertW(0,x),x=infinity);

 

Is there a problem (strange) with the new algolib, or maybe an existing problem elsewhere that shows up when algolib is present? Is it only under MacOS, or more general?

The new version of algolib has been out about 2 weeks now. It is here... http://algo.inria.fr/libraries/

I downloaded files algolib.mla and algolib.hdb, but them in a directory "/Applications/Maple/algolib". It seems to work fine. But today I had a strange problem with latex(), and...

Do you have some suggestions on how to do this?

> restart;

In the example below, I find integers that solve the equation. That solution happens to be nonnegative. But in general, just plugging in zeros may not give me a nonnegative solution. What is a good way to find a *nonnegative* integer solution, if one exists?

> aa := x^(-4)*exp(-2*x);

> pmu:=product(muval[j]^a[j],j=1..kmax);

I used to do this, but it seems I have forgotten how...

> P1 := plot(sin(x),x=-Pi..Pi);

> with(plots):display([P1]);

> plotsetup(ps,plotoutput=`aa.ps`,plotoptions=`portrait,noborder`);

When I upgraded my Mac G5 from OS 10.3 to OS 10.4, the OS X versions of Maple (Maple 9.5 and Maple 10) continued to work. But the classic versions of Maple (Maple 7 and Maple Vr5) quit working. It turns out that the classic versions will run in OS 10.4 if the following files (perhaps from an old "System Folder") are moved into the "Extensions" folder of the active classic OS 9 "System Folder": OpenGLEngine OpenGLUtility OpenGLRendererATI OpenGLRenderer OpenGLMemory OpenGLLibrary Shared Library Manager PPC At least this worked for me.
