An absolute beast of an integral solved using Feynman's awesome technique

We are....not afraid of formidable integrals cuz we know how to integrate the Feynman way. Another W for Feynman's trick and the battle was truly EPIC! Write up for the antiderivative of x^2/(x^4+1): https://www.instagram.com/p/Cu9gWumNe4X/?igshid=MzRlODBiNWFlZA== Those two integrals that end up being equal: https://youtu.be/jQ1t5_ZgvnI
