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