I won't respond to the programming issues, since Benoit has already responded.
I'll wait and see if his help solves your problems.

But I'd like to address a math issue:
Shouldn't you have a +c constant added to your integral in *every* case? NOT
just when the coefficient of x^0 is equal to 0.

(BTW: the question is rhetorical. I KNOW that you *should* have it
there...typed the calculus teacher...)
