Guess the Method: Integration by Parts / substitution at times Parts: Parts w/ substitution: ju dy = uv - fv du integrand: x sin(X) SVx -1 x dax For integrals with limits of integration: e since x logun 1 = X dv = vx -1 dx fuck = up - [v du vx logon) du = 1 dx v = 2 (x - 1) 3/2 VX -1 x x sec or logor) SV x - Ixxx = ] (x-1)322x - 17(x-1)32 dx tan (x) sinticn Part 1. Basic Integration by parts; no substitution. Compute the integrals. 1. S x ex dx
