Maple symgen result This shows Maple’s found \(\xi ,\eta \) and the corresponding canonical coordinates \(R,S\).\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= \frac {1}{x \sin \left (y \right )-y^{2}}\right ] \\ \left [R &= x, S \left (R \right ) &= -x \cos \left (y\right )-\frac {y^{3}}{3}\right ] \\ \end{align*}
