Thanks Mike!
Upgrading to Python 2.5 did the trick.

Hi,
I haven't been able to 'expand' trigonometric functions in Sage using
identities such as:
sin(x + y) = sin(x)*cos(y) + sin(y)*cos(x)
Is this currently implemented?
Thanks in advance,

Hi,
just today I came up with an idea that, I'm sure some of you had
already thought of. Anyway, it could be publicized more: to use Sage
instead of PowerPoint!
In Sage Notebook, use [Action/One cell mode] and use LaTex for nicely
typeset text and formulas. One can also embed images by attaching t

Hi,
I noticed the following (inconsistent?) behavior: saving 2D plots
works as expected (a graphic file is stored), but saving 3D plots
gives .sobj files instead (see sample code below). Is there a way to
save 3D plots from the Notebook? By the way, I know how to save them

Hi,
Current behavior for list_plot3d is "A 3-dimensional plot of a surface
defined by the list v of points in 3-dimensional space.". I was
expecting to see dots in space, not a surface; similar to this:

Hi,
I wonder what the current situation in SAGE is for dealing with PDE
and methods to solve them numerically, such as say Finite Elements.
A quick search threw this thread (which I'm afraid is not very conclusive):

Hi,
While trying to compute the Golden ratio using SAGE I noticed the

Hi Jason
Hi,
this just happened to me (maybe because I'm annoyingly slow today...):
sage: var('t')
sage: x(t) = sin(2*pi*1000*t) + 1/2*sin(2*pi*2000*t + 3/4*pi)
Exception (click to the left for traceback):

Hi,
I've been quite happy using SAGE Mac OS X Binaries (on OS X 10.4). I
also use SAGE on an Ubuntu Linux desktop. It's just that sometimes I
miss some of SAGE's (original?) functionality while using the Mac,
e.g. 'animate' needs 'convert'.
So my question is: has somebody successfully used SAGE's

Hi,
is there a way in SAGE to handle recurrences? Say, determine the
closed-form expression, or the limit as n goes to infinity, of
something like:

r_n = sqrt(a + r_{n-1})
Now, experimenting with SAGE (and using some basic Calculus), I've
noticed that this recurrence co
Hi,
I'm planning on using SAGE for some digital signal processing

For example; opening a wav, doing some filtering or DSP magic and
playing the result back (maybe using an applet like Wikipedia does).
Any ideas? Thanks in advanc
