{{#invoke:Hatnote|hatnote}} In mathematics, Rodrigues's formula (formerly called the Ivory–Jacobi formula) is a formula for the Legendre polynomials independently introduced by Template:Harvs, Template:Harvs and Template:Harvs. The name "Rodrigues formula" was introduced by Heine in 1878, after Hermite pointed out in 1865 that Rodrigues was the first to discover it. The term is also used to describe similar formulas for other orthogonal polynomials. Template:Harvtxt describes the history of the Rodrigues formula in detail.

Statement

Rodrigues stated his formula for Legendre polynomials :

A similar formula holds for many other sequences of orthogonal functions arising from Sturm-Liouville equations, and these are also called the Rodrigues formula for that case, especially when the resulting sequence is polynomial.
