Ellipse is a regular oval shape, traced by a point moving in a plane so that the
the sum of its distances from two other points (the foci) is constant
When a cone is cut by an oblique plane which does not intersect the base, it results in the formation of an ellipse.
Standard equation of the ellipse is given as
x2/a2+y2/b2=1
and eccentricity of the ellipse lies between 0 and 1
the eccentricity of an ellipse is given as
e=√1-b2/a2 when a>b
Foci of an ellipse are (±ae,0)
Major Axis=2a
Minor Axis=2b
The equation of Directrix are x=±a/e
Coordinates of vertices are (±a,0)
Length of latus rectum is 2b2/a.
