2.0 out of 5 stars Very unclear, June 24, 2008

By	Khattab O. Qattan - See all my reviews (REAL NAME)

This book is one of the most unclear concepts i have ever tried to learn. The examples are really tough and sadly have nothing to do with the exercises themselves which made my self learning very long, boring, and pretty much a waste of time. I understand the graphing, but i dont understand why they add calculus problems to it like the difference qutient. But on the plus side, the cover and the pages are really nice and good looking. But the examples themselves are long and a waste of paper, no offense. I wouldn't really recomend this book for self teaching, but u can use it maybe if u have a tutor which i dont have. Good luck shopping for a trig book! :P

2.0 out of 5 stars Needs improvement!, May 10, 2002

By	Rachelle (Los Angeles) - See all my reviews

This review is from: Trigonometry (6th Edition) (Hardcover)

The explanations in this book could be more concise for students who have other assignments to study and fulfill. Throughout all my years in reading mathematical textbooks, this one does not head straight-to-the-point. The author spends more time introducing the subject than explaining how one step is derived from another in the examples, which leaves the student to spend time figuring how one concept abruptly transitions into the next. Aside from that, the exercise questions sometimes do not relate to the examples given in the book.

1.0 out of 5 stars ..., December 14, 2007

By	Elizabeth Cox (APO, AE United States) - See all my reviews (REAL NAME)

This is the worst math book I have EVER used. Awful awful. When I needed help, did I turn to my outrageously priced trig book? Nope! Google was of more help than this book.

So, what is wrong with it?
No background. I hadn't been in school for 7 years. I was a bit rusty and this book was of no help. It has really bad examples (if you are lucky enough to get an example for the type of problem you are working) that skip steps and don't give any explanation of the concepts.

The my mathlab that comes with this book is great. It really supplements where the book fails.
