Cos 2x + 3sinx-2 = 0
Dec 06, 2007 · Substitute 1-sin^2x = cos^2x getting. 2(1-sin^2x) +3 sinx = 0-2sin^2x +3sinx +2 = 0. sinx = {-3 +/- 5}/-4. sin x = -8/-4 = 2 which is impossible and is rejected. sinx = 2/-4 = -1/2. x = arcsin(-1/2) which gives solutions in quadrants III & IV. Each solution has additional solutions by adding or subtracting 2npi where n is any integer.
