The Precalculus Study Guide is an exercise-based electronic version of the introductory chapter in the standard calculus text, providing solutions to more than 60 problems. To maximize understanding, they are each given in three formats: standard textbook format, with dedicated Maplet tutors, and with Maple commands. High school and university students in, or contemplating a calculus course, and students wanting additional insight into selected topics in algebra and trigonometry would all benefit from this guide.
