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

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

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

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))(1)/(4+5cos x)dx=

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

The integral int_(0)^(pi/2)(dx)/(1+cos x) is equal to

int_(0)^(pi//4)(dx)/((1+cos2x))

int_(0)^(pi//4)(dx)/((1+cos2x))

int_(0)^(pi//2) (1)/(4+3 cos x)dx

int_(0)^(pi//2) (1)/(4+3 cos x)dx
