Maple symgen result This shows Maple’s found \(\xi ,\eta \) and the corresponding canonical coordinates \(R,S\)\begin{align*} \\ \\ \end{align*}
\begin{align*} \\ \left [R &= \frac {y^{2}-1}{x^{2}}, S \left (R \right ) &= -\operatorname {arctanh}\left (y\right )\right ] \\ \end{align*}
\begin{align*} \\ \left [R &= \frac {y}{\sqrt {x^{2}+1}}, S \left (R \right ) &= \arctan \left (x \right )\right ] \\ \end{align*}
