`int_(1+oo)^( x^(2)/(1+x^3))dx`

The value of the integral I=int_(1)^(oo) (x^(2)-2)/(x^(3)sqrt(x^(2)-1))dx , is

int_(1)^(oo) (1)/(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

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

I=int_(-oo)^(1)(1)/(x^(2))dx

int_(0)^(oo)(x)/(1+x^(4))dx=

int_(1)^(oo)(dx)/(x^(2))

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

int_(1)^(3)(x-1)(x-2)(x-3)dx=
