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 {LegendreP}\left (-\frac {3}{8}, \frac {5}{8}, \sqrt {-x^{2}+1}\right )}{x^{\frac {3}{8}} \sqrt {x^{2}-1}}\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {x^{\frac {3}{8}} \sqrt {x^{2}-1}\, y}{\operatorname {LegendreP}\left (-\frac {3}{8}, \frac {5}{8}, \sqrt {-x^{2}+1}\right )}\right ] \\ \end{align*}
\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= \frac {\operatorname {LegendreQ}\left (-\frac {3}{8}, \frac {5}{8}, \sqrt {-x^{2}+1}\right )}{x^{\frac {3}{8}} \sqrt {x^{2}-1}}\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {x^{\frac {3}{8}} \sqrt {x^{2}-1}\, y}{\operatorname {LegendreQ}\left (-\frac {3}{8}, \frac {5}{8}, \sqrt {-x^{2}+1}\right )}\right ] \\ \end{align*}
