Title: A good text, but not enough challenging problems
Review: Thomas and Finney's 9th edition is a good textbook. I used it in AP Calculus and found it to be a good text for such a course. I consider it good in the sense that it explains the concepts clearly, but many of the problems simply require rote substitution into an formula. Admittedly, there are more challenging problems at the end of the lesson and chapter, but I only wish that there were more of these problems.
Is the review positive or negative?
