Wolfram claims those integrals don't converge. Parisse says that the integrals (results), are correct. Does that mean that for CAS purposes undef == infinity? If they are different, please explain. As the integral bounds includes 0, non-convergence occurs.

(I have a calc 1 student, in the family, and wasn't sure how to explain this).
