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.
