Find all possible values of sin x if cos x = 0.25. sin2x = 1 ( cos2x = 1 ( (0.25)2 = 1 (0.0625 = 0.9375. sin x = (x = 0.968 or (0.968. 3 Find the exact value of sin x if cos x = and x is in the fourth quadrant. Third side of triangle = From triangle sin x = but x is in the fourth quadrant, so sin x = (. 3

= 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
