Homework Statement
Solve the integral of x2sin(x) / (1+x6) from -pi/2 to pi/2.

The Attempt at a Solution
Well I am supposed to do this using the substitution method, so I tried:
u = x2
du = 2x dx which doesn't cancel out any terms
u = 1+x6
du = 6x5 dx which again doesn't cancel anything out
u = sin(x)
du = cox(x) dx useless also
Is this possible with substitution? I seem to have tried every option for u. Is there another way to do this? (without taylor series and stuff like that)
Thanks for the help!Also, I tried doing this integral on the computer, and it said it cannot be solved because it is probably a "non-elementary integral", hence the title of the thread.
