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 &= 0, \underline {\hspace {1.25 ex}}\eta &= \frac {1}{x^{2}-y}\right ] \\ \left [R &= x, S \left (R \right ) &= x^{2} y-\frac {y^{2}}{2}\right ] \\ \end{align*}

\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= \frac {2 x^{2} y -x^{2}-y^{2}}{2 x^{2}-2 y}\right ] \\ \\ \end{align*}
