For some reason I've always found Trig to be challenging but this book made it so easy to understand! I would recommend it to anyone looking to review/learn Trig, the explanations are easy to grasp and the problems are straightforward.

Trigonometry Success in 20 minutes a day by Christopher Thomas , 2007 edition,
is a welcomed text for people like me who had a hard time understanding
Trigonometry in High School .

It starts with a Pretest to assess your present trigonometry performance with a 50-question multiple choice examination to find out your strenghths and weaknesses.

It then moves into the nitty-gritty of Trigo in 20 lessons, beginning with Angles, Triangles, Pythagorean Theorem up to The Law of Sines, of Cosines, Heron`s Formula and some Advanced Problems through Calculator Trigonometry, Inverse Functions and Vectors.

well illustrated explanations with plenty of exercises and an answer key to secure your understanding ( 21 exercises just on Angles in the first chapter).

The lesson pages are not crowded offering plenty of white space so not to feel crampedand assaulted.

A Posttest of 50 questions on all the 20 lessons completes your study and comes of course with answers to evaluate your learning.

A glossary is provided as well as an Access Code to go online and get access to more exercises with immediate scoring assorted with explanations . I really appreciate this bonus.

Why 4 stars ? Well, no Index to retrieve quickly a specific point . Nevertheless
a great text for those worrying about Trigonometry; you are guaranteed a good start.

This text leaves out way to many steps. Its geared more for people who had already taken a trig course years ago, and now need a refresher. This is not for someone who has no knowledge of trig. Math is sequential, you need a sold background in algebra and a basic outline of a full geometry course to really grasp the concepts of trigonometry. Overall, it is a good book, just a little misleading.
