Ebook Trigonometry demystified: A self teaching guide

This book is for people who want to get acquainted with the concepts of basic trigonometry without taking a formal course. It can serve as a supple- mental text in a classroom, tutored, or home-schooling environment. It should also be useful for career changers who need to refresh their knowledge of the subject. This is not a rigorous course in theoretical trigonometry. Such a course defines postulates (or axioms) and provides deductive proofs of statements called theorems by applying mathematical logic. Proofs are generally omitted in this book for the sake of simplicity and clarity. Emphasis here is on practical aspects and scientific applications. You should have knowledge of middle-school algebra before you begin this book.
