They are only looking for a trigonometry book that is beginner-friendly and easy to finish.

Trigonometry for Dummies is written by Mary Jane Sterling, a mathematics teacher at the University of Peoria, for more than twenty years. She also has published a few books on algebra, pre-calculus, and a few workbooks for mathematics. As with every other dummies book, this also has explained ‘how’ and ‘why’ we use these trigonometry concepts. Everything is explained in plain English to help everyone, regardless of their age, understand trigonometry easily. Each section has a decent amount of practice problems. But it would’ve been great if there were more examples.

Trigonometry for Dummies has fewer pages than other trigonometry textbooks we covered, but it is also at the high school and college education level. Students have said that it was much easier to understand trigonometry after referring to this textbook and perform way better at their exams.

  • Suitable for Every Age
  • Decent amount of Practice Problems

A mathematics textbook was written by Micheal Sullivan, a mathematics professor at Chicago State University who published well-known fifteen mathematics textbooks on topics such as College Algebra, Finite Mathematics, Precalculus, and Statistics. Most college courses that involve trigonometry or algebra use this textbook as a reference textbook since most professors love it since it was written for math majors.

This is one of the best trigonometry textbooks for someone who at least enrolled in a college course that involves algebra and trigonometry. The author has written this book assuming that the reader already knows the basic concepts. The Textbook also includes a lot of practice problems that are most find difficult to solve.

Since this is a trigonometry textbook with over a thousand pages it will take some time to understand the concepts and finish practice problems. You may also need tutoring for the textbook at some point. So if you are not a math major or just someone who is self-studying trigonometry and algebra you should stay away from this book at least until you master the fundamental concepts.

  • Advance Level Textbook
  • Good for Math Majors
  • A lot of Practice Problems
  • Does not simplify the concepts
  • Not Beginner Friendly
  • Not for Self-Studying
  • May Need Extra Tutoring

In a Nutshell

Studying mathematical topics is hard because you have to understand the principles and apply them to practice problems until you get a good get at it. Learning trigonometry can be a bit rough, but if you could use a good trigonometry textbook and supplemental material, you could easily get better at it. There are a lot of trigonometry textbooks available for purchase. However, getting a good textbook according to your situation and learning experience also can play a role in how well you would learn and master trigonometry.
