Maple symgen result This shows Maple’s found \(\xi ,\eta \) and the corresponding canonical coordinates \(R,S\)\begin{align*} \\ \left [R &= \frac {2 x \ln \left (x \right )+y}{x}, S \left (R \right ) &= \ln \left (x \right )\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 &=-{\mathrm e}^{\frac {y}{x}} x^{3}-3 x \\ \frac {dS}{dR} &= -\frac {1}{3 R} \\ \end{align*}
