Understanding precalculus often opens the door to learning more advanced and practical math subjects, and can also help satisfy college requisites. Precalculus Demystified , Second Edition, is your key to mastering this sometimes tricky subject. This self-teaching guide presents general precalculus concepts first, so you'll ease into the basics. You'll gradually master functions, graphs of functions, logarithms, exponents, and more. As you progress, you'll also conquer topics such as absolute value, nonlinear inequalities, inverses, trigonometric functions, and conic sections. Clear, detailed examples make it easy to understand the material, and end-of-chapter quizzes and a final exam help reinforce key ideas. It's a no-brainer! You'll learn Simple enough for a beginner but challenging enough for an advanced student, Precalculus Demystified , Second Edition, Second Edition, helps you master this essential subject.
A pretty good book. The Trig section needs work as it was pretty confusing and I needed to look on the web to get more details before being able to understand what the author was discussing (maybe it was me as it has been a long time since I had a trig class and I am not sure that I truly understood it when I took it in college).
It's a math book, so what can I say, other than there seemed to be enough examples on the subjects that I was interested in. The book covers a very wide swath of mathematics and so it isn't able to carry all of the topics far enough long for the reader to understand their ultimate usefulness. That being said, I had tried starting first with Calculus Demystified (the second book in this series) and ran into some stumbling blocks because of my weak background. I'll know better in a month, of how good this book was, when I see how well the road is paved ahead.
I learned what I needed to know, but some of the techniques assume the knowledge of techniques that may fall between algebra and pre-cal which may cause confusion. The Appendix is not really adequate in this aspect.
