Greetings Group,
I was wondering if *I* could run Maple 9.5 in X11 instead of using the
Java GUI on Mac OS X. I know that this is available via the "maple
primes", but as I student (applied math whooo) I am obviously not

How to draw a grid over a geometrical object, with maple?
Thank you.

Is there any CAS that will do this? I currently own Maple but it does
not seem able to do it... Altough I would love to be corrected about
that!
What I want is to be able to work with symbolic matrices (no values, no

I've been having a number of struggles plotting various equations in
Maple 9.5 on Windows XP and was hoping others know how to solve my
problems.
1. I'd like to distinguish between lines on my plot using solid,

try the following inverse z-transform in Maple, Mathematica
1/(w*(w^2+1))
different result

I am given a certain "complicated" function and I am interested in
constructing/generating a "nice"[*] ordinary (possibly non-homogeneous
possibly non-linear) differential equation, which has this function as a
solution.

I want to draw two functions into the same plot, but the second one with
switched axis.
So I want to draw first U(x) and then U(y) into the same plot
How to do this?

sorry I haven't found an answer to this FAQ.
How can I enter a non-ascii character like a german umlaut in text input mode?
(in Maple 9.5)
Many thanks for a hint,

I'm having trouble manipulating polynomial expressions. For example if I
have the 12'th degree polynomial
normal((x^13+1)/(x+1));
I can multiply this by x^(-6) and thus get a symmetric polymonial. By making

Browsing old threads in this group I've finally understood that the
error message "Bad index into Matrix" appears in expressions like
A[i][j] because i and j are not necessarily integers. But I can't figure
out how to specify for Maple that i and j indeed are integers. Help is

i'm trying to solve a kind of multiple regression with the fit command (an
autoregression).
with(fit):
proc_ar3 := proc(pData, pOrder)

with maple 9.5 i would like to draw on the same graphic
->              ->               ->    ->
ra(t)=sin(pi *t)i  + 2*cos(pi*t) j  + 2*t
->         ->             ->       ->

I am generating fractals with Maple and I am noticing that when I start
using sequences with more than 2000 entries, Maple (9.5 Linux)
significantly slows down. Is there a way of keeping my programs really
fast?

Curious if this is expected behavior.  I was under the impression that
setting displayprecision would control the number of digits displayed
to the right of the decimal point.  That doesn't seem to happen.

I got a sequence given by a recurrent formula and would like to get an
explicit formula for its n-th term. So far, I managed to evaluate the
formula for any numerical value of n, but not for the symbolical one.
Whether Maple provides a standard routine/algorithm to carry out this ...
