Hello. I would like to define a function which is given by the evaluation of an integral. More precisely, I want f(x) to be the integral between 0 and x of exp(t**2)dt My first attempt is to create a function in the "python" sense of the term : --- var('x,t') def f(x

Hi all, In sage, as of 4.1.1, binomial( -7, 1 ) returns -7. As I understand the definition of binomial, this should be 0, since there is no set with -7 elements. Axiom returns 0 in this case. This is not really a "problem" but does give *interesting* results, when summing binomials over all int

Minimal instructions for the source are at: http://www.sagemath.org/download-source.html If you have problems, there is a more extensive installation guide: http://www.sagemath.org/doc/installation/ but hopefully you won't even need that. And if you get stuck, you can always ask here again.
