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