Hi, you have something like syntax highlight in sws2tex, see

first of all sin(pi/2) = 1.0
to understand the problem arises in your computation u should
read about floating point arithmetic and about how numbers are stored in
computers.
check this very good article.

I didn't do anything about vector() -- I could probably get to it later.
There's no good way to make a syntax like f.matrix() or f.vector()
work, and it's not someth

Hi everybody again.
Does anybody if it is possible to use the result of the function solve
to insert it in a function to resolve it analitically.
For example, I want to get the peak of the following function
>>> var('tau0,tau1')
>>> f(x) = (1-e**(-x/tau0))*(e**(-x/tau1))
For that, I simply d

That's great!
What about vector(3,f), f.vector(3), and f.matrix(3,4) or
f.matrix(5) ?
Thanks a lot David, this is what I needed.
Just if somebody else might need it, i will resolve the problem:
# declare t and tau as symbolic variables
var('t')
var('tau')
# monoexponential equation
g(t) = e**(-t/tau)
# 2-piece result (one from 0 to t0, the second from t0 to 1000
t0 = 0.2 # this

Let me explain (as the author of mwrank).There was a bug in
mwrank, found by James Wiegandt and Edray Goins, which meant that in
some cases for curves with rational 2-torsion the computed upper bound
on the rank was too high. (Technical explanation: the second descent

Dear group,
I have noticed a change in behaviour of mwrank when called from SAGE
4.3.3 to compute Selmer ranks. I am using Mac OSX 10.6.2, Power PC.
The SAGE folder is in the directory Applications. The command
u003429:~ julianaguirre$ /Applications/sage/sage -mwrank -v0 -s
gives

Hi everybody,
i was wondering, which is the best method to plot a conditional function
within an interval. For example, a function whose values are:
0 if tt0
where f(t) is a simple monoexponential decay that starts at t0. I tried
the following in Sage:
t = var('t')
def f(t,t0):
