    ive tried integration by parts, i tried substitution and i cant get it to work. i also need to figure the integral when x=1 and i keep getting 0 in the numerator. What is the best point of attack?

    You can use the chain rule for this integral. It is straightforward.

    What happens when you try ##u=1-x^2##?

    From the way you've written the integrand, you don't have a denominator, so getting the numerator = 0 isn't that big a deal.

    It's when the denominator = 0 that things blow up. :wink: :frown:
