Pronunciation: /ˈkɒn ɪk ˈsɛk ʃən/ ?
A conic section is a 2-dimensional figure formed by
the surface of a 3-dimensional double
(see figure 1). Four 2-dimensional figures that can be formed are the
ellipse, parabola, and hyperbola. Conic sections were studied as early as 200 BC by
Apollonius of Perga.
