int(1)/(cos x(sin x+2cos x))dx

int (sin x+2cos x)dx

int(cos 2x)/(1+sin x cos x)dx

int (1) / (sin x cos x) dx

int (1) / (cos x-sin x) dx

Evaluate: int(1)/((sin x-2cos x)(2sin x+cos x))dx

Evaluate: int(sin x)/(cos x(1+cos 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)

int (1 + cos x) / (sin x cos x) dx

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

int 1/(sin x cos x) dx
