Length in Ellipse
We denote length of major axis by 2a, length of minor axis by 2b and distance between the foci by 2c. Thus, the length of the semi major axis is a and semi-minor axis is b
Relationship b / w major axis, minor axis & focus:( a 2 = b 2 + c 2)
Special Cases for Ellipse
o o
Case1: c = 0 or a = b: It is a circle Case 2: c = a: It is a straight line
