The equation of an ellipse E is rand(2) === 1 ? expr(["+", Y2T, X2T]) : expr(["+", X2T, Y2T]) = 1.
What are its center (h, k) and its major and minor radius?
(h, k) = (H, K)
Major radius = MAJ
Minor radius = MIN
The equation of an ellipse with center (h, k) is \dfrac{(x - h)^2}{a^2} + \dfrac{(y - k)^2}{b^2} = 1.
We can rewrite the given equation as \dfrac{(x - negParens(H))^2}{A*A} + \dfrac{(y - negParens(K))^2}{B*B} = 1 .
Thus, the center (h, k) = (H, K).
MAJ*MAJ is bigger than MIN*MIN so the major radius is \sqrt{MAJ*MAJ} = MAJ and the minor radius is \sqrt{MIN*MIN} = MIN.
