Try
collect(numer(%)/G_C,s)/collec t(denom(%)/G_C, s);
eval(%,{G_S = 1/R_S, G_C = 1/R_C});
denom(%);
solve(%, s);
read("c:/MyPath/MyFile.txt");
and for output, you could either use save or fprintf.

Dear all,
I'm new to maple, and get stuck very easily, just like now is this case.
Perhaps you can help me a little bit.
Consider the following:
Kcl_ni := I_S - G_S*V_ni - s*C_i*V_ni - G_C*(V_ni-V_nc) = 0 :
Kcl_nc := G_C*(V_ni-V_nc) = s*C_C*V_nc :
solve({Kcl_ni, Kcl_nc},{V_ni, I_S}) ;
eval(V_ni/I_S, %) ;

discriminant of rank r quadratic form or diagonalizing symmetric matrices over finite fields

ahmora...@gmail.com (moro) — Wed, 10 Mar 2010 22:23:30 UT

I was wondering if there is a way to compute the discriminant of a
rank r quadratic form in maple?
Alternatively, is there a way to diagonalize, via symmetric row and
col operations, a symmetric matrix A over Z_p? For instance, modifying
RowReduce in LinearAlgebra[Modular]. If I can do this then I can

Why is my single quote not the one that maple expects? Can I change that?
Do you have an Idea as to how I have to set them to see what you see?
This will print an asterisk

solving for a ratio

francky.l...@telenet.be (Francky Leyn) — Wed, 10 Mar 2010 18:58:43 UT

Dear all,
I have 2 equations:
Kcl_i := I_S - G_S*V_i - s*C_i*V_i - G_C*(V_i-V_c) = 0 :
Kcl_c := G_C*(V_i-V_c) = s*C_C*V_c :
Out of these equations V_c must be eliminated.
The result is one equation with as variables V_i and I_S.
I need the ratio of them: V_i/I_S.
How do I do this?
Best regards,
Francky

That works as expected on our systems...
You could try toggling interface(ansi) from true to false or vice
versa.
Does that help? Fedora is not a supported distribution, however.
Try Ctrl-E instead (Strg-E on a German keyboard layout); please see
?editing for Maple's features (much like libreadline used by bash

text mode problem (bash)

urs.schue...@fernuni-hagen.de (Urs Schuerch) — Tue, 09 Mar 2010 15:28:40 UT

When running maple in text mode I experience the following problems:
why doesn't it print the value assigned to q?
further, when pushing the up arrow to edit and run a previous command,
the characters in the command would change.
i.e. "iquo(a,b,’q’);" would become "iq,’q’,b,’q’);" just by moving the

Making Maths More Fun & Enjoyable

MATHS- some children seen this as boring and hard, some like it but
need more encouragement and motivation….and some really love it. What
makes this different…perception or ability or the subject itself?
MATHS is a very exciting subject if we know the tactics and the fun
behind this scary and horror word.

You're not supposed to run $MAPLE/bin.XXXX/cmaple directly.
The commandline interface is supposed to be run via the shell script
$MAPLE/bin/maple which you should be invoking instead.
That `maple` script sets up an LD_LIBRARY_PATH, etc, so that shared
libs get found by the executable cmaple binary.

You have it, but it's not in a library. You need to do
and then it should work.
