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 {1}{x^{3}+x^{2}+1}, \underline {\hspace {1.25 ex}}\eta &= -\frac {x +a}{2 \left (x^{3}+x^{2}+1\right )}\right ] \\ \left [R &= y+\frac {x^{2}}{4}+\frac {x a}{2}, S \left (R \right ) &= \frac {x \left (3 x^{3}+4 x^{2}+12\right )}{12}\right ] \\ \end{align*}
