Find the least positive angle measured in degrees satisfy `sin^3x +sin^ 3 2x +sin^3 3x-(sinx+sin2x+sin3x)^3`

Find the least positive angle measured in degrees satisfy sin^(3)x+sin^(3)2x+sin^(3)3x-(sin x+sin2x+sin3x)^(3)

sin x sin 2x sin 3x

sin x sin 2x sin 3x

" int sinx sin 2x (sin3x)dx

(sin x - sin 3x)/(sin^(2)x-cos^(2)x)=2sinx

(sin x - sin 3x)/(sin^(2)x-cos^(2)x)=2sinx

Find the integrals sin x sin 2 x sin 3 x

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