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

Evaluate : int_0^(pi/2)(sin^2x)/(sin x+cos x)dx

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

Evaluate (i) int_(0)^(pi/2) (sin^(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:

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

Given int_(0)^((pi)/(2))(dx)/(1+sin x+cos x)=ln2 then the value of the definite integral int_(0)^((pi)/(2))(sin x)/(1+sin x+cos x)dx is equal to

(sin 2 kx)/(sin x)=2[cos x + cos 3 x + …+cos (2k -1)x] , then value of I=int_(0)^(pi//2)(sin 2 k x)/(sin x)cos x dx is :

(sin 2 kx)/(sin x)=2[cos x + cos 3 x + …+cos (2k -1)x] , then value of I=int_(0)^(pi//2)(sin 2 k x)/(sin x)cos x dx is :
