About This Chapter
Limits in Precalculus - Chapter Summary and Learning Objectives
Refresh your understanding of how limits are used, described and calculated in mathematics as you study these lessons. Take a look at the squeeze theorem, what it means and how to use it, and explore how graphing can help you define and understand limits. The lessons in the chapter cover the following material:
- What limits and asymptotes are
- How to annotate and describe limits
- Definition and explanation of the squeeze theorem
- Description of the properties of limits
- Equation for a tangent line

1. 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.
2. 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.
3. 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.
4. 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.
5. How to Approximate Limits From Graphs & Data Tables
In this lesson, we will review what limits are, and then we will look at how to approximate limits from graphs and how to approximate limits from data tables. We will use real-world examples to explore these methods.
6. 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.
7. 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.
8. 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.
9. Tangent Line: Definition & Equation
In this lesson, we explore the idea and definition of a tangent line both visually and algebraically. After learning how to calculate a tangent line to a curve, you will find a short quiz to test your knowledge.
