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 &= t \operatorname {KummerM}\left (\frac {1}{2}-\frac {\lambda }{4}, \frac {3}{2}, t^{2}\right )\right ] \\ \left [R &= t, S \left (R \right ) &= \frac {y}{t \operatorname {KummerM}\left (\frac {1}{2}-\frac {\lambda }{4}, \frac {3}{2}, t^{2}\right )}\right ] \\ \end{align*}
\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= t \operatorname {KummerU}\left (\frac {1}{2}-\frac {\lambda }{4}, \frac {3}{2}, t^{2}\right )\right ] \\ \left [R &= t, S \left (R \right ) &= \frac {y}{t \operatorname {KummerU}\left (\frac {1}{2}-\frac {\lambda }{4}, \frac {3}{2}, t^{2}\right )}\right ] \\ \end{align*}
