Question:
Consider the differential equation \(\frac{d^{2} y}{d x^{2}}-x y=0\). Using the transformations \(y=u \sqrt{x}\) and \(\frac{2}{3} i x^{3 / 2}=z\), where \(i=\sqrt{-1}\), show that this differential equation reduces to the Bessel differential equation
\[
\frac{d^{2} u}{d z^{2}}+\frac{1}{z} \frac{d u}{d z}+u\left(1-\frac{1}{(3 z)^{2}}ight)=0
\]
What is the solution for \(u(z)\) and \(y(x)\) ?
