Solve `4 sin x sin 2x sin 4x = sin 3x`.

Solve: 4sin x sin2x sin4x=sin3x

Solve sin x-3 sin 2x + sin 3x = cos x -3 cos 2x + cos 3x .

Solve: 4sin x.sin2x*sin4x=sin3x

Solve sin 2x=4 cos x .

Prove that sin x + sin 3x + sin 5x + sin 7x=4 sin 4x cos 2x cos x.

Prove the following Identities sin x +sin 2x + sin 4x +sin 5x = 4 cos(x/2).cos((3x)/2)sin3x

(cos 2x sin x + cos 6x sin 3x)/(sin 2x sin x + sin 6x sin 3x) =cot 5x

Solve sin2x-sin4x+sin6x=0

(cos 4x sin 3x -cos 2x sin x )/(sin 4x sin x+ cos 6x cos x)= tan 2x
