Maple symgen result This shows Maple’s found \(\xi ,\eta \) and the corresponding canonical coordinates \(R,S\)\begin{align*} \\ \\ \end{align*}

\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= \frac {\operatorname {BesselJ}\left (0, 2 x \right )}{x}\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {x y}{\operatorname {BesselJ}\left (0, 2 x \right )}\right ] \\ \end{align*}

\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= \frac {\operatorname {BesselY}\left (0, 2 x \right )}{x}\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {x y}{\operatorname {BesselY}\left (0, 2 x \right )}\right ] \\ \end{align*}
