Major and Minor Axis
An Ellipse has two axes along the x-axis and the y-axis that support its structure. They are called,
- Major axis
- Minor Axis
The axis with the longer diameter of the ellipse is called as major axis. It is denoted by the symbol ‘a’ while the smaller diameter axis is called the minor axis. It is denoted by the symbol ‘b’, and both axes intersect at the centre of the ellipse.
Half of the major axis is called the semi-major axis and half of the minor axis is called the semi-minor axis.
Ellipse
An ellipse is the locus of all points on a plane with constant distances from two fixed points in the plane. The fixed points encircled by the curve are known as foci (singular focus). The constant ratio is the eccentricity of the ellipse and the fixed line is the directrix. In this article, we will learn about the ellipse in detail.
