Hi, In Sage, this gives a totally wrong answer:
sage: f(x) = sqrt(2+sqrt(2+sqrt(2+2*cos(5*sqrt(x)+4))))*x^(-1/2) sage: integral(f, x) It takes about 10 seconds, and plotting f.derivative(x) - f makes it clear the answer is wrong. I tried sympy, but after several minutes it didn't return a result. Here's a public worksheet that illustrates things: https://cloud.sagemath.com/projects/4a5f0542-5873-4eed-a85c-a18c706e8bcd/files/support/2015-02-12-121421-integral.sagews -- William (http://wstein.org) -- You received this message because you are subscribed to the Google Groups "sage-support" group.
