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 \left (x +4\right )^{3}}\right ] \\ \end{align*}

\begin{align*} \\ \left [R &= x, S \left (R \right ) &= \frac {{\mathrm e}^{x} y}{{\mathrm e}^{-4} x \left (x +4\right )^{3} \operatorname {Ei}_{1}\left (-4-x \right )+\left (x^{3}+9 x^{2}+22 x +6\right ) {\mathrm e}^{x}}\right ] \\ \end{align*}
