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 {LegendreP}\left (-\frac {1}{2}+\frac {i \sqrt {3}}{2}, \frac {x}{5}\right )\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {y}{\operatorname {LegendreP}\left (-\frac {1}{2}+\frac {i \sqrt {3}}{2}, \frac {x}{5}\right )}\right ] \\ \end{align*}

\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= \operatorname {LegendreQ}\left (-\frac {1}{2}+\frac {i \sqrt {3}}{2}, \frac {x}{5}\right )\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {y}{\operatorname {LegendreQ}\left (-\frac {1}{2}+\frac {i \sqrt {3}}{2}, \frac {x}{5}\right )}\right ] \\ \end{align*}
