Nov 3, 2020 at 14:02 | comment | added | Iosif Pinelis | @kodlu : I just used Mathematica to compute the integral (which took Mathematica a surprisingly long time to do that) and then simplified the result mostly by hand. However, the integral can be taken by the standard in such a case substitution $u=\sqrt{1/x+c}$, which reduces the integral to one of a rational function. | |
