Summary: Excellent Book But Could Have Used a Proofreader Or Two
Comment: I was in a bit of a quandary as to how to rate this book. I bought the book and the companion "Trigonometry Workbook for Dummies" to refresh my trig skills, long rusted after nearly 50 years of little use. Both books are really quite good although the workbook could be more comprehensive. The big problem with the workbook, and to a lesser extent with the "Trigonometry for Dummies" book, is the large number of errors in the book. One works out a very complicated identity problem only to find that the stated problem is different from the problem answered due to typographical errors. I don't think I went seven pages in the workbook without finding an error. Most of the errors were changed minus or plus signs. This made maintaining confidence in the book very difficult.

One would think that a big publisher like Wiley would employ competent proofreaders. I would also expect them to have an errata sheet somewhere on their web page. But, nooo, nothing helpful there at all except a glossary they forgot to put in this book.

Overall, both books were very helpful, with the exception of not having a lot of confidence that the answer to the problem I was trying to solve would be correct.

Summary: Good, but be careful
Comment: I took calculus years ago, but I found I'd forgotten about everything about math, even algebra. The book explains trigonometry fairly well, but I found several errors. One problem contained a minus sign, but was worked out with a plus sign in the answers. Another problem had a similar mistake. Still, about every math book has mistakes, and this one does explain things well. Sometimes you have to really think to see how the author got the answer since a few steps were skipped, but that's probably a good mental exercise. I've had fun working through it and have been obsessed with finishing it at times, so I guess it's accomplishing its purpose.

Customer Rating:
Summary: a decent book
Comment: A fine book for those who are real strong in algebra. At the risk of appearing sexist, it is definitely written from an female academic's point of view. Some real-world examples would be helpful. Overall, a decent book.
