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