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