Understanding Limits: Using Notation

1. Understanding Limits: Using Notation

Join me on a road trip as we define the mathematical notation of limits. As time goes by and I traverse hills and highways, the limit of my speed changes. Learn how to write these limits in this lesson.

Symbolic Logic: Definition & Examples

2. Symbolic Logic: Definition & Examples

In this lesson, we'll cover the definition of symbolic logic, introduce some of the common symbols used, and work out some truth tables for a few logical expressions.

Using a Graph to Define Limits

3. Using a Graph to Define Limits

My mom always said I tested the limits of her patience. Use graphs to learn about limits in math. You won't get grounded as we approach limits in this lesson.

One-Sided Limits and Continuity

4. One-Sided Limits and Continuity

Over the river and through the woods is only fun on a continuous path. What happens when the path has a discontinuity? In this lesson, learn about the relationship between continuity and limits as we walk up and down this wildlife path.

Infinite Limit: Definition & Rules

5. Infinite Limit: Definition & Rules

In this lesson, we learn how to interpret limits whose values are unbounded, or infinite. We'll look at a few examples to show you how to compute these infinite limits.

How to Determine the Limits of Functions

6. How to Determine the Limits of Functions

You know the definition of a limit. You know the properties of limits. You can connect limits and continuity. Now use this knowledge to calculate the limits of complex functions in this lesson.

Understanding the Properties of Limits

7. Understanding the Properties of Limits

Graphically we can see limits, but how do we actually calculate them? Three words: Divide and Conquer. In this lesson, explore some of the properties that we can use to find limits.

Squeeze Theorem: Definition and Examples

8. Squeeze Theorem: Definition and Examples

In the Kingdom of Rimonn there are three rivers. In this lesson, learn how these waterways demonstrate the power of the squeeze theorem for finding the limits of functions.

Graphs and Limits: Defining Asymptotes and Infinity

9. Graphs and Limits: Defining Asymptotes and Infinity

Infinity is a hard concept to understand and the word asymptote is pretty intimidating. But this fun lesson will make both seem like a walk in the park as it defines both and shows their relationship using a graph.

How to Determine if a Limit Does Not Exist

10. How to Determine if a Limit Does Not Exist

In this lesson, we'll discuss when a limit does not exist. We'll begin with a description of each type of limit and when that particular type does not exist. Then, we'll use a graph to show how to recognize when a limit does not exist based on the graph of a function ''f.''

Finding Asymptotes Using Limits

11. Finding Asymptotes Using Limits

A function can have a vertical asymptote, a horizontal asymptote and more generally, an asymptote along any given line (e.g., y = x). In this lesson, we learn how to find all asymptotes by evaluating the limits of a function.

Comparing Relative Magnitudes of Functions

12. Comparing Relative Magnitudes of Functions

The magnitude of a function can be thought of as how it behaves when it is graphed. In this lesson, we will investigate five function types and how to compare their magnitudes.
