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