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 {y^{3}}{x \,y^{3}+2 y^{4}-4 x}\right ] \\ \left [R &= x, S \left (R \right ) &= y^{2}+x y+\frac {2 x}{y^{2}}\right ] \\ \end{align*}
\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= \frac {y \left (x \,y^{3}+y^{4}+2 x \right )}{x \,y^{3}+2 y^{4}-4 x}\right ] \\ \\ \end{align*}
