int_ (0) ^ ((pi) / (2)) (cos x) / (1 + sin x) dx =

int_ (0) ^ ((pi) / (2)) (sin x) / (sin x + cos x) dx = int_ (0) ^ ((pi) / (2)) (cos x) / (sin x + cos x) dx = int_ (0) ^ ((pi) / (2)) (dx) / (1 + cot x) = int_ (0) ^ ((pi) / (2)) (dx) / ( 1 + time x) = (pi) / (4)

Prove that int_(0)^(pi//2) (sin x -cos x)/(1+sin x cos x)dx = 0 .

int_ (0) ^ ((pi) / (2)) (sin x-cos x) / (1 + sin x cos x) dx

int_(0)^(pi//2) ( cos x - sin x )/( 2 + sin x cos x ) dx is equal to
