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} y}{x^{2} \left (1+x \right )}\right ] \\ \end{align*}
\begin{align*} \\ \left [R &= x, S \left (R \right ) &= \frac {y}{\left (-1+{\mathrm e}^{x} \left (1+x \right ) \operatorname {expIntegral}_{1}\left (x \right )\right ) x^{2}}\right ] \\ \end{align*}
