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 &= 2 x^{2}, \underline {\hspace {1.25 ex}}\eta &= \frac {1}{x}\right ] \\ \left [R &= y+\frac {1}{4 x^{2}}, S \left (R \right ) &= -\frac {1}{2 x}\right ] \\ \end{align*}
