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