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}^{2 i x \sqrt {2}\, \sqrt {\frac {1}{x}}}\right ] \\ \left [R &= x, S \left (R \right ) &= {\mathrm e}^{-2 i x \sqrt {2}\, \sqrt {\frac {1}{x}}} y\right ] \\ \end{align*}
