" 25."int_(0)^( pi/2)(x+sin x)/(1+cos x)dx

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

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

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

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

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

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

"int_(0)^( pi/2)(|sin x|+|cos x|)dx

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

int_(0)^( pi)(1)/(1+(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:
