int_(0)^( pi)(dx)/(3+2sin x+cos x)=

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

int_(0)^((pi)/(2))(x sin x cos x)/(cos^(4)x+sin^(4)x)dx=

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

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

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

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

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

int_(0)^(pi//2) 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:
