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 {3 y^{3}}{4 x}, \underline {\hspace {1.25 ex}}\eta &= \frac {1}{y^{2}}\right ] \\ \left [R &= y^{6}+4 x^{2}, S \left (R \right ) &= \frac {y^{3}}{3}\right ] \\ \end{align*}
