This is the newly updated Fifth Edition of the AP Calculus Problem Book, containing over 3000 problems on all aspects of AP Calculus AB and BC. Answers to all problems are included. Problems on topics which are not part of the AP curriculum are also featured (such as partial derivatives, surface area, and hyperbolic function among others) to be used after the AP exam. Also included are two different sample tests at the end of each chapter mimicking the style of the AP exam, with AP-style scoring guidelines for the free-response problems included. This book gives you lots of problems -- but in this case, that's a wonderful thing!
