Maple symgen result This shows Maple’s found \(\xi ,\eta \) and the corresponding canonical coordinates \(R,S\)\begin{align*} \\ \left [R &= x, S \left (R \right ) &= \frac {y}{x}\right ] \\ \end{align*}
\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= \operatorname {arcsinh}\left (x \right ) x -\sqrt {x^{2}+1}\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {y}{\operatorname {arcsinh}\left (x \right ) x -\sqrt {x^{2}+1}}\right ] \\ \end{align*}
