sin^(3)x +sin^(3)(x-(2pi)/3) +sin^(3)(x+(2pi)/3)=0

If the equation cos 3 x cos^(3) x + sin 3 x sin^(3) x =0 , then x is equal to

If the equation cos 3 x cos^(3) x + sin 3 x sin^(3) x =0 , then x is equal to

int_(pi//6)^(pi//3) (sin^(3) x)/(sin^(3) x + cos^(3) x) dx=

What is int_(0)^(pi//2) (sin^(3)x)/(sin^(3)x + cos^(3)x) dx ?

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

int_0^(pi/2) (sin^(3)x)/(cos^(3)x+sin^(3)x) dx =
