Hi Marshall
I'm using Ubuntu 8.04, in a laptop Dell inspiron 1420. I installed
from source. I have 3.1.1. and 3.2.3. I was checking, maxima does not
work at all. I can't do a simple example like:
sage: x = var('x')
sage: solve(x^2 + 3*x + 2, x)

What operating system and type of computer are you using? Did you
install from source or with a binary?

Hi Drake,
I didn't work. I have to versions of sage (3.1.1 and 3.2.3) running on
my laptop. Really I don't have any clue of what's happening.

Mike, thanks, you da man!

First, you should construct a polynomial. A matrix of coefficients is
not the preferred way to work with polynom
I need to find the roots of this polynomial, where are coefficients
are in this matrix:
coef=matrix([[1],[-1],[-1],[0]])
thanks in advance, and apologies if this is posted somewhere else, I
have not been able to find it.
(NOTE: looking for the MathCAD equivalent of "polyroots")

Hi Dan,
You are totally right. The problem is that Sage can't start maxima.
Here is part of the output when I typed
sage: var('x k w')
(x, k, w)
sage: f = x^3 * e^(k*x) * sin(w*x); f

Hi, I've never seen this error before. If you just start sage in the
commandline from the directory where the tex files are, can you do
symbolic operations? (i.e. works maxima ?)

hi, a hint additional to robert's method, you can parse files
directly:
doc = xml.dom.minidom.parse(file)
Also, i've written a xhtml parser with embedded sa
