Answer (1 of 14): If sin 2x - cos 2x = 1, then 2 sin x cos x - cos^2 x + sin^2 x = sin^2 x + cos^2 x, or 2 sin x cos x = 2 cos^2 x, or sin x cos x = cos^2 x, or sin x ...
0 < x < π. sin2x + 3cos2x = 0. Subtract 3cos2x from each side. sin2x + 3cos2x - 3cos2x = -3cos2x. sin2x + 0 = -3cos2x. sin2x = -3cos2x. Divide cos2x by each side. sin2x / cos2x = -3cos2x / cos2x. tan2
