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 &= -\frac {x}{3}-\frac {2}{9}, \underline {\hspace {1.25 ex}}\eta &= x y\right ] \\ \left [R &= \frac {y \,{\mathrm e}^{3 x}}{9 x^{2}+12 x +4}, S \left (R \right ) &= -3 \ln \left (-3 x -2\right )\right ] \\ \end{align*}
