" Enaluate: "(0)int(dx)/(a sin x+b cos x)

int(dx)/(sin x(a+b cos x))

Evaluate int_(0)^(pi//2) (a sin x+b cos x)/(sin x+cos x)dx

Prove that int_(0)^(a) f(x) dx = int_(0)^(a) f(a-x) dx . Hence, evaluate int_(0)^(pi//2) (sin x - cos x)/(1+ sin x cos x) dx.

int sin x sin (cos x) dx.

int sin x sin (cos x) dx

int sin x sin (cos x) dx

Evaluate :int_(0)^((pi)/(2))(a sin x+b cos x)/(sin((pi)/(4)+x))dx

int sin x sin (cos x)dx
