Maple symgen result This shows Maple’s found \(\xi ,\eta \) and the corresponding canonical coordinates \(R,S\)\begin{align*} \\ \\ \end{align*}
\begin{align*} \\ \left [R &= x, S \left (R \right ) &= \frac {{\mathrm e}^{-x^{2}} y}{x^{2}}\right ] \\ \end{align*}
\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= 1-\frac {x^{4} {\mathrm e}^{x^{2}} \operatorname {expIntegral}_{1}\left (x^{2}\right )+1}{x^{2}}\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {x^{2} y}{-x^{4} {\mathrm e}^{x^{2}} \operatorname {expIntegral}_{1}\left (x^{2}\right )+x^{2}-1}\right ] \\ \end{align*}
