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 &= 1+\frac {x \left (x a +b \right )}{c}, \underline {\hspace {1.25 ex}}\eta &= 0\right ] \\ \left [R &= y, S \left (R \right ) &= -\frac {2 c \,\operatorname {arctanh}\left (\frac {2 x a +b}{\sqrt {-4 a c +b^{2}}}\right )}{\sqrt {-4 a c +b^{2}}}\right ] \\ \end{align*}
