Essential Trigonometry: A Self-Teaching Guide

I took trig nearly 20 years ago. I needed a refresher for an engineering class. This book is awesome. It uses proofs when useful, and doesn't bother with excess "math fat." The language is clear and concise. If you need a LOT of practice problems you might want to add another guide, but this is perfect for reacquainting oneself with trig functions. Thank you Mr. Hill.

I was excited to discover a book that had such a good explanation of the concepts of Trigonometry. Tim Hill deserves a lot of credit for presenting the topic in such a great way. Many books go on for pages trying to explain Trigonometry and leave the reader clueless of the essential concepts. This book goes straight for the concepts making it brief, but offering a deep understanding. Exactly the kind of math explanations that are most useful to me - a math amateur looking to brush up and master core concepts.

Purchased this for review.

Explains everything in pretty good detail. FYI if your tracking says delivered at front door or porch and it's not there , check your mailbox.

Nice crisp presentation. Not much hand-holding here. Excellent for quick review. I found that using this for review ALONG with "The Humongous Book Of Trigonometry Problems" worked for me.

Plenty of better explained trig books, don’t bother.

needed something small for a desk reference.

Good book to get one started. Still can't replace taking the course.
