`int_0^(pi/2) (sinx)/(1+Cos^2x)dx`

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

int_0^pi (xSinx)/(1+Cos^2x)dx

Evaluate: int_0^pi(xsinx)/(1+cos^2x)dx

I_(1) = int_(0)^(pi)(xsinx)/(1+cos^(2)x)dx, I_(2) = int_(0)^(pi)(x^(2)sinx)/((pi^(2)-3pix+3x^(2))(1+cos^(2)x))dx , then

int_0^(pi/2) (dx)/(1+cos x)

int(sinx)/(1+cos^2x)dx

Evaluate int_0^(pi/2) x/(sinx+cosx)dx

Evaluate (i) int_0^pi (x sin x)/(1+cos^2 x) dx Evaluate (ii) int_0^pi (4x sin x)/(1+ cos^2 x) dx

int sinx/(1-cos^2x)dx
