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 {c^{2}}{\left (-1+x \right ) \left (1+x \right )}}\, \left (-1+x \right ) \left (1+x \right ) \ln \left (x +\sqrt {x^{2}-1}\right )}{\sqrt {\left (-1+x \right ) \left (1+x \right )}}}\right ] \\ \left [R &= x, S \left (R \right ) &= \left (x +\sqrt {x^{2}-1}\right )^{-\frac {i \sqrt {\frac {c^{2}}{\left (-1+x \right ) \left (1+x \right )}}\, x^{2}}{\sqrt {x^{2}-1}}} \left (x +\sqrt {x^{2}-1}\right )^{\frac {i \sqrt {\frac {c^{2}}{\left (-1+x \right ) \left (1+x \right )}}}{\sqrt {x^{2}-1}}} y\right ] \\ \end{align*}
