INSTRUCTIONAL UNIT: A CRASH COURSE IN TRIGONOMETRY

This trigonometry module consists of sections in PDF format as well as supporting documents. These documents are GSP animation files that I made. While you read the sections in PDF format, please refer to these supporting documents when necessary: This is essential for a full understanding of the subject matter.

PDF FILES:

0. INTRODUCTION

1. UNIT CIRCLE - ANGLE MASURE UNITS

2. TRIGONOMETRIC FUNCTIONS and TABLES

3. PERIODIC FUNCTIONS - GRAPHS OF TRIGONOMETRIC FUNCTIONS - INVERSE TRIGONOMETRIC FUNCTIONS

4. THREE TRIGONOMETRIC THEOREMS IN TRIANGLES

5. SUM and DIFFERENCE FORMULAS

PRACTICE PROBLEMS
