Maple symgen result This shows Maple’s found \(\xi ,\eta \) and the corresponding canonical coordinates \(R,S\)\begin{align*} \\ \left [R &= \frac {y}{x}, S \left (R \right ) &= \ln \left (x \right )\right ] \\ \end{align*}

\begin{align*} \\ \left [R &= x, S \left (R \right ) &= -\frac {\ln \left (-\textit {\_y1}^{2} y-x a \right )}{\textit {\_y1}^{2}}\right ] \\ \end{align*}
