Graphing Basic Functions

1. Graphing Basic Functions

Graphs are just like maps - when you know the language! Review how locations have x and y coordinates similar to latitude and longitude, and how to plot points in the Cartesian plane.

Polynomial Functions: Properties and Factoring

2. Polynomial Functions: Properties and Factoring

Everything from projectile motion to trigonometric functions can be described by polynomials. Review factoring, polynomials and quadratic functions in this lesson.

Polynomial Functions: Exponentials and Simplifying

3. Polynomial Functions: Exponentials and Simplifying

How do we keep track of a rapidly multiplying population of bunnies? Well, those are simply powers of 2. Review powers and simplify problems with exponents in this lesson.

Slopes and Tangents on a Graph

4. Slopes and Tangents on a Graph

Hit the slopes and learn how the steepness of a line is calculated. Calculate the slopes between points and draw the tangents of curves on graphs in this lesson.

Horizontal and Vertical Asymptotes

5. Horizontal and Vertical Asymptotes

No matter how hard you try to get to them, asymptotes remain out of reach. Learn about these invisible lines on graphs that show you places your equations just can't go.

Implicit Functions

6. Implicit Functions

Sometimes inputting a variable into a function 'black box' doesn't yield a simple output. Find out what happens when you can't isolate the dependent variable on one side of the equal sign.

Converting Yards to Miles

7. Converting Yards to Miles

Converting yards to miles can be done quite simply with a formula. In this lesson, we'll learn what that formula is and how we can use it to convert yards to miles in any instance. We'll explore this formula through examples and then test our knowledge with a quiz.

Semi-Major Axis of an Ellipse

8. Semi-Major Axis of an Ellipse

This lesson will define an ellipse, its semi-major axis, and a few other characteristics of an ellipse. We will also see how to find the length of the semi-major axis of an ellipse and solve an application involving this process.

How to Find the Major Axis of an Ellipse

9. How to Find the Major Axis of an Ellipse

In this lesson, we'll review the definition of an ellipse, learn how to find the major axis of an ellipse given the foci and one point on the ellipse, and look at an application of this process.
