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

int_(0)^( pi/4)(dx)/(1-sin x)

int_(0)^( pi/4)(dx)/(1+sin x)

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

Find the error in steps to evaluate the following integral int_(0)^(pi)(dx)/(1+2 sin ^(2) x )=int _(0)^(pi)(sec^(2)xdx)/(sec^(2)x+2 tan^(2)x)=int_(0)^(pi) (sec^(2)xdx)/(1+3 tan^(2)x) =(1)/(sqrt3)[tan^(-1)(sqrt3 tan x)]_(0)^(pi)=0

int_(0)^(pi)(x)/(1+sinx)dx .

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

int_(0)^( 2 pi)(dx)/(1+e^{sin x})

Prove that :int_(0)^(pi) (x)/(1 +sin^(2) x) dx =(pi^(2))/(2sqrt(2))

If int_(0)^(pi)((x)/(1+sinx))^(2) dx=A, then the value for int_(0)^(pi)(2x^(2). cos^(2)x//2)/((1+ sin x^(2)))dx is equal to

Evaluate int_(0)^(pi)(sin 6x)/(sinx) dx .
