" Q.19.Evaluate "int_(0)^(sqrt(2))(sin x-cos x)/(1+sin x*cos x)dx

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

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

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

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

Evaluate: int(1)/(sqrt(3)sin x+cos x)dx

Evaluate: int(1)/(sqrt(3)sin x+cos x)dx

Evaluate: int(1)/(sqrt(3)sin x+cos x)dx

Evaluate: int(1)/(sqrt(3)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.
