Study Notes
Conic Sections
- The shape of the locus of all points in a plane that are equidistant from a fixed point called the focus and a fixed line called the directrix is a parabola.
- Conics with a constant eccentricity less than 1 are ellipses.
- The intersection of a cone and a plane parallel to the side of the cone forms a parabola.
