(Hmm, I see it doesn't mention Laguerre's equation specifically by name, but it does come up with the Laguerre polynomials which are part of the solution.)

Thank you, that site looks like it will help out quite a bit. It looks like it give a much more detail explanation that a lot of the other site I have seen.
 

What is Laguerre Differential Equation?

Laguerre Differential Equation is a type of ordinary differential equation that is commonly used in physics and engineering to describe the behavior of systems with exponential decay or growth. It is named after the French mathematician Edmond Laguerre.

What are the applications of Laguerre Differential Equation?

Laguerre Differential Equation has many applications in various fields such as quantum mechanics, fluid dynamics, electrical circuits, and population dynamics. It is used to model the behavior of systems with exponential decay or growth, making it a valuable tool in understanding real-world phenomena.

How is Laguerre Differential Equation solved?

There is no general method for solving Laguerre Differential Equation. However, there are specific techniques that can be used depending on the form of the equation. These techniques include power series, Frobenius method, and Laplace transform. In some cases, numerical methods may also be used to approximate the solution.

What are the advantages of using Laguerre Differential Equation?
