2 cos 2x - cos x = 0 for 0 £ x £ 2p.
-
2 sin 2x - 5 sin x - 3 = 0 for 0 £ x £ 2p.
-
3 cos q - 2 = 0 to the nearest tenth of a degree for 0°£ q £ 360°.
-
4 sin q + 3 = 0 to the nearest tenth of a degree for 0°£ q £ 360°.
-
4 sin q - csc q = 0 for 0°£ q £ 360°.
-
sin 2q + 2 sin q = 0 for 0°£ q £ 360°.
-
2 cos 2x - sin x -1 = 0 for 0 £ x £ 2p.
-
cos 2x + 2 cos x - 3 = 0 for 0 £ x £ 2p.
-
cos 2q = -

sin x - cos x = 1 for 0 £ x £ 2p.
-
Eliminate the parameter t from the parametric
equations: x = 3 + sin t and y = 5 + cos t. -
Write y = sin x - cos x in terms of a single trigonometric function and then graph one period.
