conic sections are called to the curved sections generated from the intersection of any plane with a cone of revolution.
Conic sections are divided into:
Ellipse: This is a closed curve, symmetric flat arising from the intersection of a cone with a plane is not parallel to the base or the generators. The sum of the distances of a any point to the foci is constant and equal to the long axis.
Parabola: a curve is flat, open and symmetrical about its axis, whose origin is the intersection of a cone by a plane parallel to one of its lines. All points of a parabola are equidistant from a fixed point "F", called the focus and a fixed line "D" called the directrix.
Hyperbola: A plane curve, open and symmetric derivative of the intersection of a cone with a plane parallel to its axis. The difference in each of their points to other fixed on its axis, called foci, is constant at a fixed distance.
