`int (x+sin x)/(1+cos x)` is equal to

int sin xd(cos x) is equal to

int(sin x)/(1-cos x)dx

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

int(cos x-x sin x)/((xcos x)) dx is equal to

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:

int _(0)^(pi//2) (cos x - sin x)/(1+cos x sin x)dx is equal to

int e^(x)(1+sin x cos x)/(cos^(2)x)dx is equal to
