A conic section is any of several types of figures. These figures all are easily describable in terms of explicit equations in two variables with degree 2. The name conic section refers to the fact that, given two right circular cones placed tip to tip, all the conic sections can be formed by cutting through with a plane. The resulting imprint on the plane is either a sphere (or circle), parabola and hyperbola.
