Ellipse

The standard form of the equation of an ellipse with center 0,0 0, 0 and major axis parallel to the y -axis is, x2 b2 + y2 a2 =1 x 2 b 2 + y 2 a 2 = 1, where, a >b a > b, the length of the major axis is 2a 2 a, the coordinates of the vertices are 0,±a 0, ± a the length of the minor axis is 2b 2 b,

In the above common equation two assumptions have been made First that the origin of the x-y coordinates is at the center of the ellipse Second that the longer axis of the ellipse is along the x- axis The convention that the semi-major axis is the x-axis will be used throughout In this technical note both conventions for the coordinate system origin will be used The equations with the 2
