Maple symgen result This shows Maple’s found \(\xi ,\eta \) and the corresponding canonical coordinates \(R,S\).\begin{align*} \\ \left [R &= y+\frac {x^{2}}{4}+\frac {x a}{2}, S \left (R \right ) &= -\frac {\ln \left (-x -1\right )}{2}\right ] \\ \end{align*}
My program’s symgen result This shows my program’s found \(\xi ,\eta \) and the corresponding ODE in canonical coordinates \(R,S\).\begin{align*} \xi &= 0 \\ \eta &=\frac {2 x \sqrt {a^{2}+2 x a +x^{2}+4 y}+2 \sqrt {a^{2}+2 x a +x^{2}+4 y}}{1+x} \\ \frac {dS}{dR} &= \frac {1}{2 R +2} \\ \end{align*}
