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 &= {\mathrm e}^{\frac {i \sqrt {\frac {d}{x^{2} a +2 b x +c}}\, \sqrt {x^{2} a +2 b x +c}\, \ln \left (\frac {\sqrt {x^{2} a +2 b x +c}\, \sqrt {a}+x a +b}{\sqrt {a}}\right )}{\sqrt {a}}}\right ] \\ \left [R &= x, S \left (R \right ) &= {\left (\frac {\sqrt {x^{2} a +2 b x +c}\, \sqrt {a}+x a +b}{\sqrt {a}}\right )}^{-\frac {i \sqrt {\frac {d}{x^{2} a +2 b x +c}}\, \sqrt {x^{2} a +2 b x +c}}{\sqrt {a}}} y\right ] \\ \end{align*}
