The process is as shown in the figure. If you agree with my answer, please click "adopt as a satisfactory answer". I wish you progress in your study!

It is known that the equation of the ellipse is x2 / A2 + Y2 / B2 = 1E = root 2 / 2f1f1f2, which are the left and right focal points of the ellipse, and F1 is perpendicular to the intersection of the major axis
The absolute value of the intersection ellipse at m, N, Mn is equal to the root 2 to solve the elliptic equation
