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 (\frac {7}{6}, x\right )}{x^{\frac {5}{6}}}\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {x^{\frac {5}{6}} y}{\operatorname {BesselJ}\left (\frac {7}{6}, 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 (\frac {7}{6}, x\right )}{x^{\frac {5}{6}}}\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {x^{\frac {5}{6}} y}{\operatorname {BesselY}\left (\frac {7}{6}, x\right )}\right ] \\ \end{align*}
