Ellipse Distance from center to vertex = a Distance from center to co-vertex = b Distance from center to foci = c b c a Length of major axis = 2a Length of minor axis = 2b a2 = b2 + c2
Ellipse - horizontal b c a Distance from center to vertex = a a2 = b2 + c2 Distance from center to co-vertex = b Distance from center to foci = c
Ellipse - vertical a c a2 = b2 + c2 b Distance from center to vertex = a Distance from center to co-vertex = b Distance from center to foci = c
