The Integral 1/(x^4+1) from 0 to infinity

Merch :v - https://teespring.com/de/stores/papaf... Link to the german version:    • Integral 1/(x^4+1) von 0 bis Unendlich   In todays Video we are going to evaluate the integral of 1/(x^4+1) from 0 to infinity. But we are not going to use complex analysis and the redsidue theorem though. Let's solve it algebraically and by exploiting some wonderful symmetry.
