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 &= \frac {2 y}{3}\right ] \\ \left [R &= y \,{\mathrm e}^{-\frac {2 x}{3}}, S \left (R \right ) &= x\right ] \\ \end{align*}
