Here's a list of why this book sucks
1) explanation of concepts are very difficult to understand
2) Worked out examples are not clearly explained
3) will require further tutoring

The worse thing about this book is that after you finish, you still wont have a solid grasp of basic concepts of Trig

This book is terrible. I'm sure there are plenty of other books that go deeper in depth of the subject than this one. I have never had any sort of reason to write a review on a book until I had to endure a semester of this tripe. In the examples, they don't explain the problems well and then they include problems that need much more explaining than what they gave in the first place. Every tutor I encountered thought the book was bad and it made my fellow students frustrated as well. Unfortunately, if the school uses this book, you have to go along with it. I was forced to waste my money on it. Bad bad bad.

This book is not a good textbook at all. My college required it, and since my instructor is not so clear, I have no other form of learning from this material. The explanations of concepts are weak, as well as the applications of formulas to problems. At first I was pleased to see such a (physically) light weight math book, only to realize that with less weight comes a price of vague instruction. I am still in awe of the fact that this textbook was chosen by the math department at my college. It really reminds you that if someone already understands the material, they can hardly relate to those who don't. That is what this book seems to be; a text written from the perspective of people who are knowledge in the subject, to people who somewhat already comprehend trigonometry.

If you have a math mentality, then this book may work, but for me (who did very well in algebra with a great book "College Algebra with Modeling and Visualization (4th Edition)") this book is not even slightly satisfactory.

i want to buy the book but my class requires the code also and i was wondering is the school code included with the book?

I bought this book for a roommate, I helped with the homework... I wish I had a book like this when I took my classes back in the... easy examples step by step very explanatory.

This book is just fine as a trig book, but it follows the current trend of greedy publishers squeezing students for extra money by convincing professors to use HORRIBLE online content, with a one time use access code in the book. This forces students to buy new or pay the publisher a fee to access the online content. I cannot stress strongly enough how awful this online content is. It is a very poorly made flash interface and it makes doing homework much more time consuming and frustrating. When was the last time you needed a decimal approximation for the measure of an angle correct to seven digits? That is just one of many stupid issues I had with the homework they provide. You will spend more time trying to figure out how to properly input your answer than you will spend finding the answer using trig. Even my professor agreed that the content was ridiculous after some questions from the class.

The author takes you through a step-by-step understanding of trigonometry in an easy to understand manner. Most of the chapters are self-explanatory and help to prepare you for the concepts, problems, and self-quizzes that follow each lesson and chapter. There are some chapters that are a bit more difficult to follow than others, and the rationale for learning the topics are a bit unclear, however the positives far outweigh the positives in this text.

This book is great! I haven't had to read through it too much, but the examples are helpful and some of the problems are actually rather challenging. My favorite feature of this book is its size, though. This book is fairly thin so it's really light. Something I value more than the problem sets, honestly.

This is a pretty good Trig textbook. Some concepts are thoroughly explained, while others leave much to be desired. It is a good book if you have a clear professor. Otherwise, I might look elsewhere.

I needed this book for college. The college was charging well over $100 dollars and I had a very limited income. The price was great and the book was brand-new! Great deal!
