= after substituting u = sin x and using cos2x = 1 – sin2x. Similarly when sin is to an odd power. Use sin2x = and cos2x = = after substituting u = tan x and using sec2x = 1 + tan2x = after substituting u = sec x and using tan2x = sec2x - 1 = after tan2x = sec2x – 1. Now expand out and use reduction formula for
