Chapter 6, Problem 51E(choose chapter or problem)
The differential equation
\(y^{\prime \prime}-2 x y^{\prime}+2 \alpha y=0\)
is known as Hermite’s equation of order after the French mathematician Charles Hermite (1822–1901). Show that the general solution of the equation is \(y(x)=c_{0} y_{1}(x)+c_{1} y_{2}(x)\), where
\(y_{1}(x)=1+\sum_{k=1}^{\infty}(-1)^{k} \frac{2^{k} \alpha(\alpha-2) \cdots(\alpha-2 k+2)}{(2 k) !} x^{2 k}\)
\(y_{2}(x)=x+\sum_{k=1}^{\infty}(-1)^{k} \frac{2^{k}(\alpha-1)(\alpha-3) \cdots(\alpha-2 k+1)}{(2 k+1) !} x^{2 k+1}\)
are power series solutions centered at the ordinary point 0.
