Ch 11: Functions for Trigonometry: Help and Review

About This Chapter

The Functions for Trigonometry chapter of this High School Trigonometry Help and Review course is the simplest way to master the basics of functions. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of working with functions.

Who's it for?

Anyone who needs help learning or mastering high school trigonometry material will benefit from taking this course. There is no faster or easier way to learn high school trigonometry. Among those who would benefit are:

  • Students who have fallen behind in understanding how to graph the different types of functions
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning math (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about functions
  • Students who struggle to understand their teachers
  • Students who attend schools without extra math learning resources

How it works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the Functions for Trigonometry chapter exam.

Why it works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the Functions for Trigonometry chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any functions question. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

What is a Function: Basics and Key Terms

1. What is a Function: Basics and Key Terms

Mapping numbers sounds complex, but we do it when we buy gasoline. We pump gasoline, and the gas station charges us based on the amount of gas that we pump. Learn how this relates to functions while reviewing the basics and notations in this lesson.

Functions: Identification, Notation & Practice Problems

2. Functions: Identification, Notation & Practice Problems

A function is simply a rule that takes one number and turns it into another. But some special conditions must apply for it to be a true mathematical function. Learn about those conditions and how we write functions here!

What Is Domain and Range in a Function?

3. What Is Domain and Range in a Function?

The domain and range are the possible outputs and inputs of a function. In this lesson, learn about what might restrict the domain and how to figure out the domain and range from a graph.

What is a Power Function? - Definition, Equations, Graphs & Examples

4. What is a Power Function? - Definition, Equations, Graphs & Examples

Power functions have many different varieties of graphs. Use this lesson to distinguish the difference between different types of power functions. Test your knowledge with a short quiz after the lesson!

What is a Radical Function? - Definition, Equations & Graphs

5. What is a Radical Function? - Definition, Equations & Graphs

Radical functions operate very differently than regular functions. This lesson covers the definitions, equations, and graphs that you will need to know to be successful with radical functions.

Discontinuities in Functions and Graphs

6. Discontinuities in Functions and Graphs

In this lesson, we talk about the types of discontinuities that you commonly see in functions. In particular, learn how to identify point, jump and asymptotic discontinuities.

How to Graph Piecewise Functions

7. How to Graph Piecewise Functions

Piecewise functions are specific functions that have more than one piece. There is a special trick to graphing these type of functions, which you will learn in this lesson.

How to Find the Domain of Piecewise Functions

8. How to Find the Domain of Piecewise Functions

The domain of any function is all the values that x can be for that function. Piecewise functions are special functions that have different parts with unique rules for each part. This lesson will show you how to find the domain for piecewise functions.

Transformations: How to Shift Graphs on a Plane

9. Transformations: How to Shift Graphs on a Plane

What is a transformation? Well, it's something that transforms one function into another! To see what I mean and how that looks, check out this lesson!

Inverse Trigonometric Functions: Definition & Problems

10. Inverse Trigonometric Functions: Definition & Problems

In mathematics, an inverse operation can reverse the effect of another operation. This lesson explains how inverse trigonometric functions work and provides examples of how they are used in scientific fields and real-life situations.

SohCahToa: Definition & Example Problems

11. SohCahToa: Definition & Example Problems

SOHCAHTOA is a mnemonic device that is used in mathematics to remember the definitions of the three most common trigonometric functions. This lesson will explain each one and give examples, and you'll have the opportunity to take a quiz at the end to solidify what you've learned.

Special & Common Trig Values: Explanation & Overview

12. Special & Common Trig Values: Explanation & Overview

For certain angles - called special angles - you can calculate exact trigonometric values. This lesson will discuss these special angles and their common trigonometric values. There will be a quiz at the end of the lesson to solidify your knowledge.
