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 &= x, S \left (R \right ) &= \frac {y}{\cot \left (x \right )}\right ] \\ \end{align*}
\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= \frac {i \sin \left (2 x \right ) \ln \left (\cos \left (2 x \right )+i \sin \left (2 x \right )\right )-2 \cos \left (2 x \right )+2}{-1+\cos \left (2 x \right )}\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {\left (-1+\cos \left (2 x \right )\right ) y}{i \sin \left (2 x \right ) \ln \left (\cos \left (2 x \right )+i \sin \left (2 x \right )\right )-2 \cos \left (2 x \right )+2}\right ] \\ \end{align*}
