Publisher Description
This book presents and introduction to trigonometry using only degrees. It will be helpful for a student or class needing a gentle start to the subject or one trying to get a preview of trigonometry before studying it in radian measure. Topics include the basics of how to evaluate and graph trigonometric functions, proving identities, solving equations, and solving triangle problems.
The book provides standard textbook features such as worked examples, problems sets with answers, review sections, and a glossary. The text also takes advantage of the iBook format with video tutorials, hints, and quizzes.
While designed to support work in an Algebra 2 and Trigonometry course, this book has also been used by students learning on their own for enrichment or acceleration.

It’s so straightforward and easy to use. Goodbye Radians (good riddance) and hello degrees!
Great trig resource!
A great resource that is concise and easily navigable for students. Unique among textbooks in that students are able to work through the material independently. The questions and examples ask students to think deeply about topics (rather than just memorize formulas and relationships) and ensure that they are making deep connections within the material. Very easy to use. Students really enjoy the ebook format as well. Can be used within a pre-calculus class to teach trig or in a calculus class to review trig quickly.
Fabulous!
I never thought I would use fabulous to describe a trigonometry resource, but it is such a user friendly book. There’s a logical progression to the units presented, and the problems presented at the end of each section are quite comprehensive. I used this book with my 10th grade Algebra 2 class, and it was so refreshing to present a unit to the class that didn’t require as many outside resources and supplementary materials as I typically use with other units. Instead, I could spend the time I would typically spend coming up with problem sets and so on coming up with activities and applications of trig to further reinforce their learning. Using this book, I found that my class was able to move through the trig unit in a more efficient & speedy manner than otherwise. I’ll be using the book again!
