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

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

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

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

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

cos3xcos^(3)x + sin3x sin^(3)x=0

Integrate : int sqrt((sin x- sin^(3)x)/(1-sin^(3) x))dx

int sqrt((sin x-sin^(3)x)/(1+sin^(3)x))dx=
