The Maple V Share Library was a wonderful facility for mathematicians comprising some 140 Maple routines, packages and worksheets written by Maple users and contributed freely to the Maple community. John Maplenut has written a short program which allows the Maple V Share Library for Windows to be accessed directly from all versions of Maple up to and including version 10. You can access the Package from the Maple Application Center or from John Maplenut - Updated Maple V Share Library.

### incompatible $-char November 21 2005 by Toolbox 0 3 I was trying to generate a derivative of randomized order in Maple T.A. It seems impossible to me since the$ in the Maple syntax of
diff(function,x$n) and the$ in the Maple T.A./brownstone syntax needed to denote a variable are incompatible.

Coding, for instance,
$n = range(2,5,1);$function = maple("diff(x^5,x$($n))");
or
$n = range(2,5,1);$function = maple("diff(x^5,xn)");
in the algorithm section makes Maple T.A. complain about a syntax error immediately

Coding
$n = range(2,5,1);$function = maple("diff(x^5,x\$n)");
jvm 1 | To Maple --> diff(x^5,x2)
being passed to Maple (taken from wrapper output).

### Inverse Laplace not working in this...

I'm running Maple 10.02, Mac OS X.4.3, and Java 1.5, and when I give Maple an inverse laplace transform with a number, it returns the correct answer. But when I give it the same thing but replace the number with an arbitrary constant (i.e., I replaced 4 with k) it doesn't seem to be able to figure it out. Any suggestions on this?

If I have the X and Y variable all done up and I am trying to find a way to figure out if their is a way to make up a quadratic equation with maple. and can maple find the inflextion point of this curve ? Any help would be appreciated. Thanks Jp

As a newbie to maple, I was wondering how do I find the maximum of a equation under contraint. i can find some but for this one I can't ... and it's getting to me f=1000*x+7500*y under constraint: g=10000000-(20000*x^0.8)*y^1.2 and for f=(20000*x^0.8)*y^1.2 under constraint: g=125000-1000*x-7500*y Who do I find the maximum using MAple 10 !!!???? Tx for the help

### Simplification with Side Relations

November 14 2005 by
I've posted a worksheet and some code for simplification with side relations. What makes this code interesting is that it properly handles rational expressions, using an algorithm is from my M.Sc. thesis. You can download the code from the Maple Application Center here, or from my personal webpage here. The code requires Maple 10.

### Square Root of a Number - only positive...

Quick question: in maple , sqrt(4) returns 2. Why not plus/minus 2, since -2 is also a valid square root of 4? Thanks! Bryan

Create new document (or worksheet) with content below and execute it step by step: > restart; > Eval(diff(v(z),z),z=H)==eval(diff(v(z),z),z=H); Eval(diff(v(z),z),z=H)=diff(v(H),H) > v:=z->z*H; v:=z->z*H > value((1)); H=2H As you can see, result of eval, which in this case is equivalent to subs(z=H,diff(v(z),z)), at the right side of first equation leads to wrong final result :( This...
