Query: Do not buy this book if you are just beginning Trigonometry.

This book is good for one thing, a Quick Review. I suppose I can't blame CliffsNotes, since that is given in the title of the book. I bought this book when I was beginning to learn Trigonometry, along with another textbook. I found that a lot of the things the textbook went over was not even mentioned in this Quick Review book. If you have taken Trigonometry in the past and want to refresh some of the basic trigonometry concepts, then this book is for you. However, if you know nothing about Trigonometry and want to learn about it, this book will do nothing but CONFUSE you.Most people that will look into these books are people who want to learn the subject for their first time, so take my advice: instead of buying this book, save that money towards a better, complete basic trigonometry textbook.
