Customer Reviews

a first course in trig
If you have never done trigonometry before, Sterling gives a gentle introduction. She assumes some previous acquaintance with geometry and simple algebra and analytic geometry. But not too much of the latter, so don't let this scare you off.

The trig concepts are slowly introduced and explained at some length. With plenty of examples. Now, you really should tackle as many of the problems as possible. Yes, it takes time. But if you want a solid, fluid grasp of trig, you have to spend the time to familiarise yourself with sine, cosine, tangent, cotangent, secant and cosecant.

There are certainly numerous relationships between these functions. You don't have to know all of them. But being acquainted with them, and knowing where to look for formulae in a book like this is useful.

Too Many Errors; Proofreading is Missing
I was in a bit of a quandary as to how to rate this book. I bought the book and the companion "Trigonometry 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 this workbook, and to a lesser extent with the "Trigonometry for Dummies" book, is the large number of errors and typos 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 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 the main trig 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.

Excellent reference book
bought the books for my daughter who is an elgebra teacher, who wants to
go on. She is enjoying the books very much and is on the sixth chapter of the trig. book and workbook. She is also working the pre-calculus book and workbook. So far as a mom I'm batting a hundred. Thank you.
