    U Substitution: Solving Definite Integral of [(x^2sinx)/(1+x^6)]*dx

    The problem: The definite integral of [(x^2sinx)/(1+x^6)]*dx on the interval -∏/2 ≤ x ≤ ∏/2 I need help figuring out what the u should be for substitution. I've been trying to make the (1+x^6) my u, but I don't know if this is what I should be doing.
