Solve the equation `3 - 2cos theta - 4 sin theta - cos 2theta + sin 2theta =0`

Solve : 3-2 cos theta -4 sin theta - cos 2theta+sin 2theta=0 .

Solve : 3-2 cos theta -4 sin theta - cos 2theta+sin 2theta=0 .

Solve : 3-2 cos theta -4 sin theta - cos 2theta+sin 2theta=0 .

Solve the general vlaue. 3-2cos theta -4sin theta - cos 2 theta + sin 2 theta =0

Solve the equations: sin 2theta - cos 2 theta - sin theta + cos theta = 0

Solve the equation 2cos^(2)theta+3sin theta=0

Solve 3 cos^2 theta - 2 sqrt3 sin theta cos theta - 3 sin^2 theta = 0

Solve 2cos^(2)theta + 3sin theta=0

If 0 lt theta lt pi/2 , the solution of the equation sin theta - 3 sin 2 theta + sin 3 theta = cos theta - 3 cos 2 theta + cos 3 theta is
