Introduction

Trigonometry is an ancient mathematical art. It has been studied by civilizations as far back as the ancient Sumerians. Today, it’s used by astronomers, pilots, engineers, and in so many more situations that you will learn about in Worldwide Trigonometry.

Professor DeWitt’s book is set up to make sense to students. In each chapter, they are first introduced to a real life application of the topic they are about to learn. As each topic is taught, students are presented with graph images, examples, and easy to follow proofs. Each chapter is divided into subchapters, each with their own set of problems for students to test their knowledge as they learn. Finally, at the end of each chapter is a series of exercises that combine all topics learned in that section of the book.

Our textbook comes in two forms: print, or digital. The digital version is especially convenient; you will be able to download the book right after purchase and begin learning. One more thing that you’ll notice is the price. We strive to keep our textbooks as affordable as possible, which means you’ll be able to start learning Trigonometry for under $10.

This book will teach you how to use trigonometry. The conversational nature of the text, paired with the rigor of the ideas, will prepare students to pass any trigonometry exam, and prepare them to take on more mathematics later on.
