Trigonometry--A Complete Introduction: A Teach Yourself Guide

Great organization and pace to the book. Explanations are generally effective. There are some questions with phrasing susceptible to more than one interpretation, completely unclear, or requiring assumptions, such as referring to sin and cos of two angles but not being told explicitly they are adjacent angles. Overall it's still a great book.

Easy to read. Haven't finished the book yet, but so far it's a good refresher.

I know most of us forget trig, which is high school math. I barely remember anything about trig from high school myself. I am only two chapters into this book and it has allowed me figure out how to code a pretty interesting system in 3D space. And there's more to come that will probably make it even better.

The book overall was great, provided you have a calculator. I was looking for a refresher on periodic functions, so this definitely did the trick. The one additional thing I would have liked to see was iterative methods for calculating sine and cosine values. In other words, when the calculator presents the sine of an angle, how did it arrive at that number?

This Book is Amazing.

Nice book and very interesting and I will be glad to get more information about this book good job nice

I bought this to brush up and reference. It covers the basics fairly quickly. But the writing uses some inaccurate terminology. Like referring to the Pythagorean Identity as "Pythagoras's Theorem." Though they are related, the theorem and identity are conceptually different. The book is cheap enough and gets the main idea across if you want a basic understanding before tackling a college course like precalc.

an excellent book on trigonometry and solving problems involving triangles.

My husband said the Trigonometry book is excellent overall - very helpful indeed and arrived very promptly. Thank you.

Introduction progressive à la trigonométrie, bon ouvrage.

not bad

Justo ahora empecé y ya me encanta, no es difícil y bastante intuitivo.

Good book. Covers the fundamental concepts very well.
