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 &= -x -\frac {1}{3}, \underline {\hspace {1.25 ex}}\eta &= y x\right ] \\ \left [R &= \frac {y \,{\mathrm e}^{x}}{\left (1+3 x \right )^{\frac {1}{3}}}, S \left (R \right ) &= -\ln \left (-3 x -1\right )\right ] \\ \end{align*}
