Abstract
Conic sections, or conics, include the various geometric figures created by the intersection of a plane with a cone. It is important to note that the definition of a cone includes the surface generated by a straight line that moves so that it always intersects the circumference of a given circle and passes through a given point not on the plane of the circle. The point, called the vertex of the cone, divides the cone into two “halves” called nappes.
