Chapter 8: Techniques of Integration ____________________________________________________________ 8.1 Integration by Parts Product Rule x Example 1: ∫xe dx Example 2: ∫ x · lnx dx Example 3: ∫ lnx dx = ∫lnx · 1 dx Example 4: Example 5: Example 6: Example 7: Example 8: ____________________________________________________________ 8.2 Trig Integrals 1. For: n n−1 - If n is odd, then: sin x = sin x · sin x Note: use sin x + cos x = 1to rewrite it in terms of cos x. - If n is even, then: use the double angle formula to reduce the power. Example 1: ∫sin x dx = − cos x Example 2: Ex
