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

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

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

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

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

int 1/(sin x cos x) dx

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

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