We are having problems solving the indefinite integral of the following function:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\frac{dx}{\sqrt[4]{1+x^4}}[/tex]

We tried the substitution [tex]t^4=x^4+1[/tex], but we got stuck.

Our professor tried solving it, but he also encountered difficulties.

Any suggestion is apreciated.

(wolfram alpha says that the integral is a hypergeometric function, but it must be simpler)
