1. Conic Sections An Introduction

2. Conic Sections - Introduction Similar images are located on page 604 of your book. You do not need to try and recreate each drawing in your notes

3. Conic Sections - Introduction A conic is a shape generated by intersecting two lines at a point and rotating one line around the other while keeping the angle between the lines constant.

4. Conic Sections - Introduction The resulting collection of points is called a right circular cone. The two parts of the cone intersecting at the vertex are called nappes. Vertex Nappe

5. Conic Sections - Introduction A “conic” or conic section is the intersection of a plane with the cone. The plane can intersect the cone at the vertex resulting in a point.

6. Conic Sections - Introduction The plane can intersect the cone perpendicular to the axis resulting in a circle.

7. Conic Sections - Introduction The plane can intersect one nappe of the cone at an angle to the axis resulting in an ellipse.

8. Conic Sections - Introduction The plane can intersect one nappe of the cone at an angle to the axis resulting in a parabola.

9. Conic Sections - Introduction The plane can intersect two nappes of the cone resulting in a hyperbola.
