About This Chapter
Analytic Geometry and Conic Sections - Chapter Summary and Learning Objectives
Conic sections, otherwise known as circles, ellipses, hyperbolas and parabolas, are the shapes you get when you cut a slice through two cones. Use the lessons included in this chapter to explore their basic characteristics and investigate the relationship between their foci and vertices, so you can graph and solve equations for conic sections with ease. Once you work your way through this chapter, you should be able to:
- Write the equations for conic sections in standard form
- Graph ellipses, hyperbolas and parabolas
- Calculate the distance of a circle

1. Defining and Graphing Ellipses in Algebra
Watch this video lesson to find out what makes ellipses so unique. Learn what kind of shape an ellipse is, how you can create one yourself and how you can graph an ellipse by just looking at the numbers in the equation.
2. How to Write the Equation of an Ellipse in Standard Form
In algebra, we have equations that make our life so much easier. Some equations are able to tell us information without hard math. Watch this video lesson to see how the equation of an ellipse does this.
3. The Circle: Definition, Conic Sections & Distance Formula
Watch this video lesson, and you will learn what makes a circle a conic section. Also learn how to calculate the circumference of a circle. You will learn about the one important measurement that you need for any circle.
4. The Hyperbola: Definition, Vertices, Foci & Graphing
In this video lesson, we'll learn what a hyperbola is and how to graph one using the standard equation to find the center point, vertices and focus points.
5. How to Write the Equation of a Hyperbola in Standard Form
When it comes to equations in algebra, there is most always a standard form that provides us with useful information. Watch this video lesson to learn how to write the standard form equation of a hyperbola by using information about the hyperbola.
6. The Parabola: Definition & Graphing
Watch this video lesson to learn what a parabola is and how you can graph it. Find out how to extract useful information from the standard form equation of a parabola to help you graph it.
7. How to Write the Equation of a Parabola in Standard Form
After watching this video lesson, you will be able to write the equation of a parabola in standard form when given just two important points from the parabola. Learn what these two points are and how they relate to the parabola.
8. How to Identify a Conic Section by Its Formulas
In algebra, we have a formula for everything. Take a cone and slice it and we have a formula for the shape that results. Watch this video lesson to learn how to distinguish between these formulas.
