It has the coordinates (x, y) = (2, 3) and (x, y) = (2, 3). On the XY coordinate system based on a sequence and length between the two focuses of the ellipse is equal to 2c, because the phase between the focus () to (). There is a center point is (0, 0)
Has coordinates (x, y) = (2,3) and (x, y) = (2,3) in XY coordinate system, respectively, and the focal length between two of the ellipse equal to the distance between the focal 2c (). and () is the midpoint is (0,0).
To coordinate X Y (,) = (2 3), and X Y (,) = (2 3), in XY coordinate system respectively, and the length between the focus from both of the times 2C due to the distance between the focus. () and () is 0 0 midpoint (,).
