The differential equation of the form 1 - x²)y^′′ - 2xy' + n(n + 1)y 0 is called?

The differential equation of the form 1 - x²)y^′′ - 2xy' + n(n + 1)y 0 is called?

Explanation

The differential equation (1 - x²)y'' - 2xy' + n(n + 1)y = 0 is known as Legendre's equation.

It arises in problems with spherical symmetry, such as solutions to Laplace’s equation in spherical coordinates.
