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