Use the identity tan2(x) = sec2(x) − 1. ii. Do a substitution (u = sec(x)). Examples: • Odd power on sine: Use u = cos(x). ∫ sin3(x) cos2(x)dx = ∫ sin2(x) cos2(x) 

Instead this is a simple integral to perf 2018-03-22 · Explanation: I = ∫( sec2x √1 − tan2x)dx. us ethe substitution. u = tanx. ∴ du = sec2xdx. ⇒ I = ∫( sec2x √1 − u2) × du sec2x. I = ∫ du √1 −u2.
