I'm using maple 10.04 to make some (simple but very long) polynomial
computations. I have 1 GB ram on my computer but every time maple uses
about 510 mb it stops and give an error message.
The message is about a kernel connection lost.

Is it OK to attach Maple mw files to posts on this newsgroup?
I can understand that files with a lot of graphics might require excessive
memory if included in the attachment. An unexecuted mw file, however, would
use much less time-bandwidth product and could be executed after

# It is often useful to describe a sequence a_n by a generating function.
# Now given an *exponential* generating function A(x) for a_n, how can we
# recover the sequence efficiently?
# Here is my solution, but there are certainly better ones, which I would

I am using Maple 9.03 on a Mac G4 using Mac OS 10.4.6. This is basically a
unix operating system with a Mac interface.
From time to time, I run into situations when I cannot open stored files
because I get messages indicating that the file is already open. I can quit

I have figured out the conformal command well enough to plot a Smith chart.
restart:
sz:=10:
with(plots):

Consider the parametric plots:
  p1 := plot([f1(t), g1(t), t=0..t1], view=a1..b1):
  p2 := plot([f2(t), g2(t), t=0..t2], view=a2..b2):
and their composite:

I'm trying to impose my own simplifications on expressions, given
properties of some symbolic function such as for all g(x), g(x)f(x) =
(g(x)-g(0))/x or something similar.
I'm having a good deal of trouble figuring out how to actually do this

Is this simple procedure a good way to map a function f over the
leaves of an expression?
rmap:= proc(f,e)
 if e::atomic then

What is the series formula for 1/ln(x) about x=1 ?

I want to find a function (probably a spline) which interpolates the
point (2,1) and (3,0) such that I can extend it to the right by 0 and
to the left by 1 C^2-smoothly. With other words, I seek a function
which equals 1 for all x<=2, equals 0 for all x>=3, is defined

I would like to know how to get Maple to colorize the area between two
(or more) curves; also, would it be possible to set the transparency of
these coloured areas so that I could see where certain domains overlap?
Many thanks,

Deal ALl:
Now I have one intergral problem. The function is uniform distribution
in the range [20,40], so
f(x):=  1/20   when x falls in [20,40];

I wrote the following in maple 8:

L:=1; detuning:=1.05: k:=1*2*Pi/L*detuning: c=1; omega=k*c; r1:=0.05:
r2:=0.05:

Is out. Its an update on the Maplesoft site. If you can't find it there
is a link on www.versionstracker.com

What would be very helpful for me to learn Maple would be railroad diagrams
such as Wirth used to describe Pascal syntax. I have great difficulty
understanding where to put or leave out certain features. For example, I
cannot form a rationale for where colons, semicolons, ...
