NettetI'm trying to find ∫ x x d x, but the only thing I know how to do is this: Let u = x x. ∫ x x d x = ∫ u d u = u 2 2 = ( x x) 2 2 = x 2 x 2 But it's certain that this isn't the correct way to evaluate that, and the answer must be wrong. calculus integration exponentiation Share Cite Follow edited Jan 12, 2016 at 16:04 Martin Sleziak 51.5k 19 179 355 NettetTry making a substitution x = tan u. Notice then that ( 1 + x 2) 2 = ( 1 + tan 2 u) 2 = ( sec 2 u) 2 = sec 4 u and d x = sec 2 u d u So the indefinite integral is now ∫ 1 sec 2 u d u = ∫ cos 2 u d u. This new integrand should be easier to integrate. Just remember to change your limits to get the proper evaluation. Share Cite Follow
