The method illustrated in this section is useful in solving, or at least getting an approximation of the solution, differential equations with coefficients that are not constant. Euler Equations – In this section we will discuss how to solve Euler’s differential equation, \(ax^{2}y'' + . Recursion relation. Following recursion relations of Hermite polynomials, the Hermite functions obey ′ = − − + + and = − + + + ().Extending the first relation to the arbitrary m th derivatives for any positive integer m leads to () = ∑ = (−) −!(− +)! − + ().This formula can be used in connection with the recurrence relations for He n and ψ n to calculate any derivative of.

An affirmative answer to the question, would provide an ``if and only if'' condition for polynomial solutions for differential equations of this nature. More importantly an affirmative answer would indicate that if you have any linear operator on the space of polynomials.
