Introduction

Master Math: Trigonometry is part of the Master Math series, which includes Master Math: Basic Math and Pre-Algebra, Master Math: Algebra, Master Math: Pre-Calculus, Master Math Geometry, and Master Math: Calculus. Master Math: Trigonometry and the Master Math series as a whole are clear, concise, and comprehensive reference sources providing easy-to-find, easy-to-understand explanations of concepts and principles, definitions, examples, and applications. Master Math: Trigonometry is written for students, tutors, parents, and teachers, as well as for scientists and engineers who need to look up principles, definitions, explanations of concepts, and examples pertaining to the field of trigonometry.

Trigonometry is a visual and application-oriented field of mathematics that was developed by early astronomers and scientists to understand, model, measure, and navigate the physical world around them. Today, trigonometry has applications in numerous fields, including mathematics, astronomy, engineering, physics, chemistry, geography, navigation, surveying, architecture, and the study of electricity, light, sound, and phenomena with periodic and wave properties. Trigonometry is one of the more interesting and useful areas of mathematics for the non-mathematician. This book provides detailed, comprehensive explanations of the fundamentals of trigonometry and also provides applications and examples, which will hopefully provide motivation for students to learn and become familiar with this truly interesting field of mathematics.
