:<math>R_n(x) = \frac{\sqrt{2}}{x+1}\,L_n\left(\frac{x-1}{x+1}\right)</math>
 
where <math>L_n(x)</math> is a [[Legendre polynomial]]. These functions are eigenfunctions[[eigenfunction]]s of the singular [[Sturm-Liouville problem]]:
 
:<math>(x+1)\partial_x(x\partial_x((x+1)v(x)))+\lambda v(x)=0</math>
