Ch 10: Conic Sections

Watch online math video lessons to learn about the graphs of ellipses, parabolas and hyperbolas. Each lesson includes a self-assessment quiz and the chance to test your own understanding of conic sections and their related equations and graphs.

Conic Sections - Chapter Summary and Learning Objectives

Anyone who has ever eaten an ice cream cone or donned a party hat is familiar with this geometric shape, but have you ever studied the curves you get when a cone is intersected by a plane? Let our experienced instructors improve your geometry knowledge with lessons on conic sections, such as ellipses, hyperbolas and parabolas. The illustrated videos included here can familiarize you with the components of their equations and their graphs. By the time you reach the end of this chapter, you should be able to do the following:

• Identify the directrices of parabolas, hyperbolas and ellipses
• Describe the relationship between foci and directrices
• Write equations for each of these conic sections

Video Objectives
The Focus and Directrix of a Parabola Learn what a focus and directrix are. Practice identifying them in the graphs of parabolas.
Finding the Equation of a Parabola from the Focus and Directrix Write the equation for a parabola when given the focus and directrix.
Foci and the Definitions of Ellipses and Hyperbolas Examine the distance between the foci and directrix of an ellipse. Do the same for hyperbolas.
Derive the Equation of an Ellipse from the Foci Write an ellipse's equation when given coordinates for the foci.
Derive the Equation of a Hyperbola from the Foci Write a hyperbola's equation when given coordinates for the foci.
Practice with the Conic Sections Hone your ability to write equations and identify the graphs of hyperbolas, ellipses and parabolas.
