Great text to accomodate a AP Calculas course
This text is tried and true, It has been published for many years by Larson. And has been revised heavily every periodic edition, to keep the text fresh for students. Upon entering a Calculus coarse, there is a multitude of problems for the student to try and grasp the many theorems and concepts over the course of the chapters. This text is simply the best there is as I compared to other Calculus texts.
