Pretty Good Study/Self Teaching Guide
Reviewed in the United States on February 3, 2014
I'm mostly self educated. As a result I go through many books like this in any given year. I like Trigonometry DeMystified specifically, and, in general, I like the whole DeMystified series. These are great books for high school and college students, or for 42 year old autodidacts like myself.
My one complaint, is the one I have with nearly all modern math books... there is no theory. It's all about the mechanics of problem solving, and memorization. But again, 99.9% of modern math books are that way. I only mentioned it to explain why I didn't give the book 5 stars.
