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