int_(0)^(oo)(log x)/(1+x^(2))dx

Let A=int_(0)^(oo)(log x)/(1+x^(3))dx Then find the value of int_(0)^(oo)(x log x)/(1+x^(3))dx in terms of A

The value of the integral int_(0)^(oo)(x log x)/((1+x^(2))^(2))dx is 0(b)log7(c)5log13(d) none of these

int_(0)^(oo)(x logx)/((1+x^(2))^(2)) dx=

int_(0)^(oo)(x logx)/((1+x^(2))^(2)) dx=

int_(0)^(oo)(log(1+x^(2)))/(1+x^(2))dx=

int_(0)^(oo)(log(1+x^(2)))/(1+x^(2))dx=

int_(0)^(1)(log(1+x))/(1+x^(2))dx
