Editor's Notes and Comments:
Product Description:
Here’s a complete, easy-to-grasp course in trigonometry that takes the form of a fantasy novel. The King of Carmorra and his subjects have many practical problems to solve, and their answers can be found by applying principles of trigonometry. Readers follow along and learn to solve many different problems that can be reduced to triangular diagrams. They learn the laws of sine and cosine, trigonometric functions and inverse functions, waves, conic sections, polynomial approximation, and much more. The book is filled with instructive exercises and their solutions, plus illustrative drawings, graphs, and diagrams. This new edition contains updated coverage on using graphing calculators and computer spreadsheets for solving trigonometric problems.

This is a great resource for teachers who want to teach the difficult concept of trigonometry in a simple, steady fashion - through the use of story telling.
I like it over the textbook approach.

Ok, so I'm an archaeologist, just finished my masters degree in archaeology. However, I specialize in 3D visualization. My master's thesis was on 3D laser scanning of fossil casts. Anyway, I don't have a background in computer science or math, but because of this book I was able to pickup enough trig to write a 3D graphics program and finish my masters. I'm no rocket scientist, and I hate borring math books. So say what you want about this book's corny storyline, at least it's not a list of formulas and numbers. I recommend this book.

Like many other reviewers, I found the endeavor to imbed trig into a fairy tale very unamusing at best. The math concepts covered were hard to keep straight, since you had to keep re-reading the crappy story to refresh your memory. I can't imagine that anyone could really learn trig (or anything) with this kind of approach. And the author shouldn't have even attempted to write it...not without some serious background work in creative writing anyway.

This is by far the worst workbook I have ever encountered. I would give this piece of crapp "negative infinity stars" just to express my anger, if it were possible. I have spent a month and a half of my summer studying for trig using this book which ended up as a waste of effort and, most importantly, time. The summer is the only time where can I boost my brain and get ahead of everybody, and even sometimes become smarter than the teachers (hee!hee!).
The thing that annoys me the most was the blasted organization of this book. The stupid fairy tale was the entire gist than learning trig. Each chapter was focused on a dilemma faced by the king and his servants, and hardly anything about trig. It took me 3-4 days just to interpret each chapter due to these: the lack of examples, the lack of practice following the lesson before the new stuffs are taught (I call it "try it"), the tone is for a 8 year old (hey, wow! a 8 year is learning trig), and learning the materials can be a toil since the informations are, rather than stated directly like most workbooks, implied in the story, meaning you will waste time rereading the stupidstory again and again trying to comprehend it. Another thing, you have to understand the story in order to actually learn trig in T.E.W (who said that!).
Mr. Douglas A. Downing has written a pain in the head. Why does he have to teach us trig by the usage of a gay fairy tale. He could have taken an easier turn by just teaching trig directly to us instead of deriving ways to make the story relevant to trig, then we are more into the story (a reason why I didn't purchase Calculus the Easy Way). You have to give him credit for being creative but all his works just turned out to be B.S. Maybe he was on crack. One thing is for certain, I will never purchase anything with the name Douglas A. Downing on it.

This book was not that helpful to me. I have had trigonometry before and purchased this book as a refresher. There are very few examples throughout the text, which makes it very difficult to solve the exercises at the end of each chapter.
