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 &= \operatorname {WhittakerM}\left (-\frac {i}{2}, \frac {1}{2}, 2 i x +4 i\right )\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {y}{\operatorname {WhittakerM}\left (-\frac {i}{2}, \frac {1}{2}, 2 i \left (2+x \right )\right )}\right ] \\ \end{align*}
\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= \operatorname {WhittakerW}\left (-\frac {i}{2}, \frac {1}{2}, 2 i x +4 i\right )\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {y}{\operatorname {WhittakerW}\left (-\frac {i}{2}, \frac {1}{2}, 2 i \left (2+x \right )\right )}\right ] \\ \end{align*}
