Use integral by parts to find the integral fr sin^2 x, choose 1 as the first fn and sin^2 x as second

him1618 Group TitleBest ResponseYou've already chosen the best response.0
Then use sin^2 x as the first fn and the log part as the second one and do integral by parts

@mahmit2012 great work, but the second is an indefinite one I believe.

mahmit2012 Group TitleBest ResponseYou've already chosen the best response.2
indefinite integral has no close function solution so for an exam it is impossible. I sure there in an symmetric interval and the answer is zero because the function is odd.
