`sin x sin 2xsin 3x sin 4x`

sin 2x.sin 3x.sin 4x

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

Solve: 4 sin x sin 2x sin 4x =sin3x.

If 4 sin x.sin 2x.sin 4x = sin 3x then theta =

If f(x) = |(sin x + sin 2x + sin 3x, sin 2x , sin 3x),(3 + 4 sin x, 3, 4 sin x),(1 + sin x, sin x, 1)| then the value of int_0^(-pi//2) f(x) dx equals :

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

underset(x to 0)"Lt" (sin 7x-sin 5x+sin 3x-sin x)/(sin 6x-sin 4x+sin 2x)=

Prove that : (cos 4x sin 3x - cos 2x sin x)/(sin 4x .sin x + cos 6x .cos x) = tan 2x
