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
