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 &= 0, \underline {\hspace {1.25 ex}}\eta &= x^{-\frac {1}{2}+\sqrt {5}} \sinh \left (\sqrt {3}\, x \right )\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {\sqrt {x}\, x^{-\sqrt {5}} y}{\sinh \left (\sqrt {3}\, x \right )}\right ] \\ \end{align*}

\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= x^{-\frac {1}{2}+\sqrt {5}} \cosh \left (\sqrt {3}\, x \right )\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {\sqrt {x}\, x^{-\sqrt {5}} y}{\cosh \left (\sqrt {3}\, x \right )}\right ] \\ \end{align*}
