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 &= \frac {\left (x^{2}+1\right )^{2}}{x^{\frac {7}{2}}}\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {x^{\frac {7}{2}} y}{\left (x^{2}+1\right )^{2}}\right ] \\ \end{align*}

\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= \frac {\left (x^{2}+1\right )^{2} \ln \left (x^{2}+1\right )+2 x^{2}+\frac {3}{2}}{x^{\frac {7}{2}}}\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {x^{\frac {7}{2}} y}{\left (x^{2}+1\right )^{2} \ln \left (x^{2}+1\right )+2 x^{2}+\frac {3}{2}}\right ] \\ \end{align*}
