This page describes the various two dimensional conic sections that can be obtained.[1]
Concept #1 Conic sections
Learning objectives
- Conic Sections are figures that can be formed by slicing a three dimensional right circular cone with a plane.
- There are different ways to do this, and each way yields a different figure.
- These figures can be represented on the graph as well as algebraically.
- The four conic sections are circles, ellipses, parabolas, and hyperbolas.
Notes for teachers
- The general equation for all conics is
- Ifthen the curve is an ellipse, circle, point or no curve.
- Ifthen the curve is a parabola,2parallel lines, 1 line or no curve.
- Ifthen the curve is a hyperbola or 2 intersecting lines.
