AP Calculus Summer 2017

1 AP Calculus Summer 017 Welcome to AP Calculus. I hope this course proves to be a challenging, yet rewarding endeavor for you. Calculus will be unlike any other math class you may have taken, filled with new ideas, concepts, and applications. While the material may be new, solving the problems that are presented in this course will require a strong foundation in problem solving. This summer assignment focuses on the skills that will be necessary to be successful in Calculus. All of the problems in this packet require the tools that you have learned in Algebra and Precalculus. Please read all directions carefully. All answers are to be placed on the last pages in their designated spots. You are free to write on the packet, but please make sure your work is neat and organized. On some sections of this assignment, it is recommended that you not use a calculator. More than half of the AP Calculus Eam does not allow a calculator, so it would be a good idea to adhere to these recommendations. This entire packet will be turned in on September 5, 017, the first day of class and will be counted for a grade. If you would like to use scrap paper, you may attach all loose-leaf paper to the assignment and include it when you turn in your work. If there are any questions or concerns that you may have during the summer please feel free to me at twaltrich@gmahs.org. I would recommend that you do not do the entire packet at one time, but rather, spread out the assignment over the entire summer. And do not what until the last minute to begin your work. Best of luck to you this summer and I look forward to a great year. Mr. Waltrich
