## Homework Statement

[itex] \displaystyle \int_0^{\infty} \dfrac{x^2-1}{x^4+1} dx [/itex]

## Homework Equations

## The Attempt at a Solution

If I separate the integral I get

[itex] \displaystyle \int_0^{\infty} \dfrac{x^2}{x^4+1} dx - \int_0^{\infty} \dfrac{1}{x^4+1} dx[/itex]

But these two integrals are itself complicated.
