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}{x^{3}}, \underline {\hspace {1.25 ex}}\eta &= -\frac {a \left (1+x \right )}{2}\right ] \\ \left [R &= y+\frac {a \,x^{4}}{8}, S \left (R \right ) &= \frac {x^{3}}{3}-\frac {x^{2}}{2}+x -\ln \left (1+x \right )\right ] \\ \end{align*}
