int(sin x)/(sin x-cos x)dx" equals "

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

If int_(0)^((pi)/(2))(dx)/(1+sin x+cos x)=In2, then the value of int_(0)^((pi)/(2))(sin x)/(1+sin x+cos x)dx is equal to:

The value of int(dx)/(2+sin x+cos x) equals

int (dx)/(sin^2 x cos^2 x) equals :

int (1)/(sin x cos x)dx is equal to

int (sin x - cos x)dx is equal to :
