`sin 4x sin 8x`

Find the integral sin 4 x sin 8 x

Evaluate the following integrals: int sin 4x sin 8 x dx

Show that (i) sin ^(2) 6 x-sin ^(2) dot(4) x=sin 2 x sin 10 x (ii) cos ^(2) 2 x-cos ^(2) 6 x=sin 4 x sin 8 x

Integrate the following functions: sin 4x sin8x

Integrate the functions sin4x sin8x

(" sin 8x cos x- sin 6x cos 3x")/(" cos 2x cos x - sin 4x sin 3x")=

What is the value of {sin (x+y) -2 sin x+ sin(x-y)} /[cos (x-y) +cos (x+ y)-2 cos x] xx [(sin 10x- sin 8x)/ (cos-10x + cos 8x)] ? {[sin (x+y] -2 sin x+ sin(x-y)}//[cos (x-y) +cos (x+ y)-2 cos x]} xx [(sin 10x-sin 8x)//(cos10x + cos 8x)] का मान क्या है?

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

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