`sin 3 x + 2 csin 4x + sin 6x = 4 cos ^(2) x sin 4x`

cos 4x =1- 8 sin ^(2) x cos ^(2) x

Solve sin 2x - sin 4x + sin 6x =0.

If sin 2x = 4 cos x , then x =

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 :

Find the general solution of sin x + sin 5x = sin 2 x + sin 4 x .

(sin 3x + sin x ) sin x + (cos 3x - cos x) cos x =0

Prove that (sin 5x - 2 sin 3x + sin x)/(cos 5 x - cos x)= tan x

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

int (2 cos x - 3 sin x)/(6 cos x + 4 sin x) dx

Solve sin 2x -sin 4x+sin 6x=0
