Given is the differential equation (x y^{prime prime}+(1-x) y^{prime}+n y=0). (a) Determine one of the basis solutions
Question:
Given is the differential equation \(x y^{\prime \prime}+(1-x) y^{\prime}+n y=0\).
(a) Determine one of the basis solutions for this differential equation, when \(n=2\), using a Frobenius method.
(b) The Laguerre polynomial \(L_{n}(x)\) is in fact a solution of this differential equation as given by the Rodrigues formula \(L_{n}(x)=e^{x} \frac{d^{n}}{d x^{n}}\left(x^{n} e^{-x}ight)\). Using this formula, specify the Laguerre polynomial \(L_{2}(x)\). What is the value of the arbitrary constant in part (a) to obtain the Laguerre polynomial solution \(L_{2}(x)\) ?
