Dear all, I had a problem with integration and this is the smallest problem I could find that fails. I want to integrate P: P : exp(2^(3/2)*x^2 - sqrt(2)*x^2); integrate(P,x); but then maxima says: `quotient` by `zero` If I contract the exponent to sqrt(2)*x^2 using radcan then it will integrate, but I don't know if this always solves 'the problem', whatever that may be (well, some intermediate expression gets zero and ratinvert fails in rat3b.lisp). Best, NB
