I know this is not a school forum...(adsbygoogle = window.adsbygoogle || []).push({});

But I think this problem has been solved multiple times all over the internett, but now I am unable to find a complete soultion for this problem.

1/(x^4+1)

I think it also have been solved multiple times on this site.

Could anyone help me find a complete solution? (Link to thread here)

The basic outline I remember from reading about it before is

1. Rationalize the denominator

2. Split the integral into two mean integrals

3. Divide top and bottom by x^2

4. Factor

5. Substitution

But as I said, I am unable to find it now.
