There is some work bei
Thanks very much for the reply.

Hi,
I have been trying to install sage4.1 on ubuntu 8.04 by following the
steps
described in the readme file, i.e. I downloaded the source code ,
unzipped it to the subdirectory sage/sage-4.1 in my home directory,
and started "make" from there. This has ended up in
the following error (trailing
I'm on holiday but will look into this when I can.

Hi,
Attached is the code.
x = var('x')
def f(x):
if (x > 0):
return x**2
elif (x <= 0):
return -x**2
f(x).integrate(x, 0, 10)
output:
Traceback (most recent call last):
