Get Your Head Around: Basic Trigonometry I

Formatted especially for reading on tablet devices, this book explains the basic ideas behind trigonometry using no-nonsense plain English. Simple and clear diagrams make it easy to see what is being explained. As you go through the book, practice questions with worked solutions will help you fully grasp the ideas and concepts. Don’t worry if you have no previous knowledge of trigonometry, or even of what an ‘angle’ is. This book starts right at the very beginning and builds up slowly. By the end of the book you will fully understand things like Pythagoras’ theorem, sines, arcsines, cosines, arccosines, tangents and arctangents.
