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 &= 1, \underline {\hspace {1.25 ex}}\eta &= -x +\frac {1}{2}\right ] \\ \left [R &= y+\frac {x^{2}}{2}-\frac {x}{2}, S \left (R \right ) &= x\right ] \\ \end{align*}
\begin{align*} \\ \left [R &= \frac {\left (2 x^{2}-2 x +4 y-13\right ) {\mathrm e}^{2 x}}{4}, S \left (R \right ) &= x\right ] \\ \end{align*}
