Finding solutions of the Regge-Wheeler equation is in many cases the first step in the study of Schwarzschild black holes and modern perturbation theory as well as many other fields. Here, a quasi-exact analytical solution of the radial Regge-Wheeler equation is reported via a proposed ansatz after elegant transformations.
