*The conic sections* Here you can see a plane moving though a cone.  Most of the time the plane intersects the cone in a curve.  These curves are called *conic sections* .  They have famous names and formulas: *Circles:*  x² + y² = r² with r 0 *Ellipses:*  ax² + by² = r² with a, b, r 0 *Hyperbolas:*  ax² - by² = r² with a, b, r 0 *Parabolas:*  y = ax²  with a 0 I...
