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

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

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

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

Prove that : int_(0)^(a) f(x) dx = int_(0)^(a) f(a-x)dx hence evaluate : int_(0)^(pi//2) (sin x)/(sin x + cos x) dx

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

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

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

Examples: int_(0)^((pi)/(4))(sin 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:
