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

The derivative of tan^(-1)((sin x - cos x)/(sin x + cos x)) , with respect to x/2 , where (x in(0,pi/2)) is

3. (sin x+cos x)(1-sin x cos x)=sin^(3)x+cos^(3)x

tan y = (sin x + 1-cos x) / (sin x-1 + cos x)

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

If f(x) =(1+sin x - cos x)/(1-sin x - cos x ), x != 0 , is continuous at x = 0 , then f(0) = ………
