Maple symgen result This shows Maple’s found \(\xi ,\eta \) and the corresponding canonical coordinates \(R,S\)\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 1, \underline {\hspace {1.25 ex}}\eta &= {\frac {1}{2}}\right ] \\ \left [R &= y-\frac {x}{2}, S \left (R \right ) &= x\right ] \\ \end{align*}

\begin{align*} \\ \left [R &= x, S \left (R \right ) &= -\frac {\ln \left (x -2 y\right )}{2}\right ] \\ \end{align*}
