" 29."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:

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

Prove that: int_(0)^( pi/2)(sin x)/(sin x-cos x)dx=(pi)/(4)

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

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

int_(0)(pi//2) ( x dx)/(Sin x + Cos x)=

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

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