Maple symgen result This shows Maple’s found \(\xi ,\eta \) and the corresponding canonical coordinates \(R,S\)\begin{align*} \\ \\ \end{align*}
\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= \frac {\operatorname {EllipticE}\left (i x \right )}{x \left (x^{2}+1\right )}\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {x \left (x^{2}+1\right ) y}{\operatorname {EllipticE}\left (i x \right )}\right ] \\ \end{align*}
\begin{align*} \left [\underline {\hspace {1.25 ex}}\xi &= 0, \underline {\hspace {1.25 ex}}\eta &= \frac {\operatorname {EllipticCE}\left (i x \right )-\operatorname {EllipticCK}\left (i x \right )}{x \left (x^{2}+1\right )}\right ] \\ \left [R &= x, S \left (R \right ) &= \frac {x \left (x^{2}+1\right ) y}{\operatorname {EllipticCE}\left (i x \right )-\operatorname {EllipticCK}\left (i x \right )}\right ] \\ \end{align*}
