A, that is the issue.
Thanks

For one thing, it doesn't execute, and it
I don't see what the issue is with the code below:
phinS=e^(i*n*pi*x/a);
phim=e^(-i*m*pi*x/a);
a=var('a');
assume(a > 0);
n=1;
m=1;
integrate(phinS*phim,x,-a,a)
I get this undecipherable error:
Traceback (most recent call last):integrate(phinS*phim,x,-a,a)

Thank you Dominique,
I didn't realize that is_locally_represented_number() is defined to return
True if and only if m is locally represented by Q over the *rational* numbers.
(I misunderstood the documentation for the function.) In that case, you are
correct.
Is there a function in Sage that r
42 is (integer) represented by form x^2 + y^2 + z^2 : 42 = 1^2 + 4^2 +

42 is locally (rationaly) represented by form x^2 +4 y^2 + 4z^2 : 42 =
1^2 + 4(4/2)^2 + 4(5/2)^2

Hi all,
I've done some work in Java, HTML, CSS, JavaScript, ActionScript 3.0 and
recently Python.
I have a project I'm working on where I'd like to set up a very simple Sage
server, to function as follows: The server will receive Sage or Maxima
code, execute the code, and send back the result.
Hi, Jim,
Thanks for the reply. I tried your suggestions (below), but I am having
trouble running from a script, not the Sage or iPython interface for which
TKAgg works fine. As for the script trials I did, #1 doesn't work for
either pylab plot or D.show() (a Sage Graph plot). #2 is not releva
From earlier thread, either of two work-arounds worked for me in Sage 6.2:Work-around #1:sage: import matplotlibsage: matplotlib.use(‘agg’)sage: import matplotlib.pyplot as pltWork-around #2:rename ~/.matplotlib/matplotlibrc to .matplotlib/matplotlibrc.bakJim Clark-Original Message-

I am having problems with matplotlib, Sage plotting and, apparently,

from my computer except for the file buried in Sage-6.2/.../mpl_data/. All
