## Customer Reviews

### ⭐⭐⭐ 







  
  
    Light Practice but the Problems are too easy.
  

*by N***F on Reviewed in the United States 🇺🇸 on November 18, 2022*

As with Learning Express Geometry Success, this book offers plenty of problems. The rub is that the problems are very easy.  This my be a great starting point BEFORE a high school or college course, but too easy to be much help DURING the high school or college course.

### ⭐⭐⭐⭐⭐ 







  
  
    Excellent, but not perfect
  

*by L***N on Reviewed in the United States 🇺🇸 on March 3, 2013*

Excellent book to self teach trigonometry. It's well organized, the material is presented well and in the proper order. The questions and answers were superb. I read the complete book and did all the exercises. There are lots of paper space, so often I did the problems right in the book with a pencil. I've never had that before in a math book, but I liked it, It really helped make the problems easier to do. Negatives: I found 7 typos in the book, not too bad. The online practice exercises are only a comprehensive 60 question test. Thus, the online exercises are not a $29.95 value as advertised. I would have liked chapter specific additional questions. However, the questions in the book itself were sufficient. To self teach, I highly recommend this book. You probably can't find better. I give it a top score, excellent, but not perfect. If you are looking for that one book that can teach you trigonometry, start to finish, this is that book.

### ⭐⭐⭐⭐ 







  
  
    Great book
  

*by R***E on Reviewed in the United States 🇺🇸 on August 3, 2015*

You can review for standardized tests with this book, but you are better off adding a tutor or class. I remember taking this stuff in high school. Now that I am older, it is hard to learn all over again. With just half hour a day, you can teach yourself this stuff. Ingenuous!
