Maple symgen result This shows Maple’s found \(\xi ,\eta \) and the corresponding canonical coordinates \(R,S\).\begin{align*} \\ \\ \end{align*}
\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= {\mathrm e}^{i \sqrt {-\csc \left (x \right )^{2}}\, \ln \left (\csc \left (x \right )-\cot \left (x \right )\right ) \sin \left (x \right )}\right ] \\ \left [R &= x, S \left (R \right ) &= \left (\csc \left (x \right )-\cot \left (x \right )\right )^{-i \sqrt {-\csc \left (x \right )^{2}}\, \sin \left (x \right )} y\right ] \\ \end{align*}
