## Using Transformations to Graph Trig Functions (5 Examples) [Video]

In this video, I discuss the six basic trigonometric functions and their graphs. I cover transformations such as a change in period, phase shift, amplitude, and vertical and horizontal shifts. I work on five examples in detail.

## Introduction to Functions and Function Notation (Lots of Examples) [Video]

In this video I give an introduction to functions by working through several examples. I illustrate functions through the use of diagrams, lists, and equations. Then I demonstrate how to use function notation by working through several examples. I also work through several examples on finding the domain of a function and finding the zeros of a function.

## Trigonometric Functions (A Unit Circle Approach) [Video]

In this introduction to the six trigonometric functions we explain references angles and the unit circle. We also discuss solving right triangles. Many examples are given.

## Angles and Their Measure (What’s Your Angle?) [Video]

Do you know what an angle is? I’ll explain the difference between a geometric angle and a trigonometric angle. I’ll go over what angles are, measuring angles, converting between degrees and radians, and the basic types of angles. I then cover the Arc Length formula and the Area of a Sector formula. I work through many examples involving these formulas. Angles and their measures are an essential starting point for any study into trigonometric functions.
