This Life of Fred Trigonometry Expanded Edition is a hardcover book designed for students who want to prepare for the trigonometry test. Written by Stanley F. Schmidt, Ph.D., the book as in the typical style of LOF, provides an interesting storyline along with learning the concepts for Trigonometry. Answers are provided - but as the lessons become a little more challenging, we found that some of the answers leaped ahead of our understanding. Overall, this was challenging but my son did a great job of working through and seeking additional online support when he didn't quite understand.
