A long time since i posted at physics forums. Anyways, try helping me solve the following integral(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\int\frac{1}{x^{2n} + 1}dx[/tex]

I tried many ways but all futile. The best way with which i could come up was factorising the denominator by de moivre's theorem. By finding the 2nth roots of unity. Hence i was able to express the denominator in a better way. But thats it. Dead end. I dont why but i get a feeling that we may able to do the sum by that way.

I am sorry that i am not able to presnt much work to you.

Hoping that you may be able to do the problem.
