0(23*)quad int(1)/(sin x cos^(2)x)dx

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

int_(0)^(pi) x sin x cos^(2)x\ dx

int_(0)^(pi) x sin x cos^(2)x\ dx

Find the following integrals: ( i ) int(sin x+cos x)dx( ii) int cos ecx(cos ecx+cos x)dx( iii) int(1-sin x)/(cos^(2)x)dx

int_(0)^(pi) x sin x. cos^(2) x dx

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

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