Cos 2x + 3sinx-2 = 0

cos2x = cos^2x - sin^x = 1 - 2 sin^2 x (using cos^2 x + sin^2 x = 1) Hence cos2x - 3 sinx = 1 - 2 sin^2 x -3 sin x = 2. Rearranging, 0 = 2 sin^2 x + 3 sin x + 1 = 0. Let s = sinx (just to simplify the notation), then 2 sin^2x - 3 sinx + 1 = 2s^2 - 3s + 1 = 0. To solve, just factor: (2s +- 1)(s + 1) = 0. The solutions are 2s + 1 = 0, s = -1/2
