Yep - the standard math functions (and constants like pi) are available in
the math module. Just do
from math import *
and away you go. See the documentation for exactly which functions are
available (it's basically what you get from C's math.h, I think).

If you are doing matrix based stuff, have a look at numerical python (sorry
I don't have the URL handy, but it's available at www.sourceforge.org). Of
course if it's an assignment, using a specialised package may be considered
as having too much assistance from outside sources.
