 Just as described, Good Value August 27, 2008
The text book was just as described. If the opportunity comes up to purchase from this supplier again, I would.

I'm a high school student who's adv. pre-calc class uses this book. I'm writing to say that without the notes and lectures from my teachers, I would have no idea how to do anything. This book fails to give any clear explanations of topics. The examples provided are rarely the type of problems given in the work that follows. The only good part about the book are the questions, which aren't as repetative as other texts and give good challenges. However, the "information" at the start of each section is minimal and irrelevant at best.

This is an EXCELLENT advanced mathematics book. I am currently a high school student using this book on my own. Never mind the criticism of the "unclear explanations" in each section by the other reviewers. The book briefly states what is needed to do the exercises, and the majority of the "major" theorems in advanced mathematics are proved in the exercises themselves (in fact, that is why so many of the exercises are so challenging). In this way (other books just prove the theorems for you and allow people just to memorize the proof), the author allows you to figure things out for yourself. This book also has a wide scope. However, one tiny fault of this book is that it does not convince you of some of the important facts (and these theorems are definitely not beyond the level of the book), for example the "Rule of 72." Also, this book is not for the average person. It requires a lot of critical thinking. Therefore, if you are not a real math person, I would suggest you get this book along with another advanced mathematics book with more detailed explanations so that you can compare and contrast the two.
 Review From An Unimpressed Student December 19, 2005

This book fails to give adequate examples at the beginning of each section and provide enough information about the given topic. Further, the examples that are provided are either 1) easy in relation to the actual problems in the "written exercises" section or 2) not relevant to the actual problems in the "written exercises" section. Also, the examples that are given sometimes miss key steps and are therefore confusing. This leads to much frustration. The actual problems though can be quite challenging and appropriate if the reader actual understands the basic underlying principles of the problems. However, the book on occasion supplies inaccurate or incorrect solutions to these problems (the odd number problems in the "written exercises," the "class exercises," and "chapter test" solutions are located in the back of the book).
I happen to have on hand another trignometery book. Although old and coming from a pre-calculator age (never mind a pre-computer age as well), this book at least supplies accuarte examples at the beginning of each section. I recommend (although out of print): New Plane And Spherical Trigonometry, Surveying, And Navigation by G.A. Wentworth. Ginn And Company, 1903; or just about any other trigonometry math textbook or precalculus textbook ever published.
