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 &= \frac {{\mathrm e}^{-\frac {1}{3} x^{3}-x}}{10}, \underline {\hspace {1.25 ex}}\eta &= \frac {x^{2} {\mathrm e}^{-\frac {1}{3} x^{3}-x}}{10}\right ] \\ \left [R &= -\frac {x^{3}}{3}+y, S \left (R \right ) &= \int 10 \,{\mathrm e}^{x +\frac {1}{3} x^{3}}d x\right ] \\ \end{align*}

My program’s symgen result This shows my program’s found \(\xi ,\eta \) and the corresponding ODE in canonical coordinates \(R,S\).\begin{align*} \xi &= \frac {{\mathrm e}^{-\frac {1}{3} x^{3}-x}}{10} \\ \eta &=x^{2}+\frac {{\mathrm e}^{-\frac {1}{3} x^{3}-x}}{10} \\ \end{align*}
