@anorton After this reopening, should we choose one of these two questions and to be left open and close the other one as a duplicate? Integration of $\int\frac{1}{x^{4}+1}\mathrm dx$ and How can I compute the integral $\int_{0}^{\infty} \frac{dt}{1+t^4}$?

@MartinSleziak Since all the indefinite integral questions are merged (example), there's already a link to the question we reopened. So, we probably don't have to worry about them.
