Name: Calculus AP - Summer Assignment 2017 All questions and concerns related to this assignment should be directed to Ms. Eisen on or before Wednesday, June 21, 2017. If any concerns should arise over the summer, please email both the teacher and supervisor listed below: Teacher: Ms. Eisen deisen@dumontnj.org Supervisor of Mathematics & Science: Ms. Warnock dwarnock@dumontnj.org This assignment is due by Friday, September 8th. Anything handed in after that will be considered late and you will lose points. It will be graded and returned to you the following class period. This assignment will be graded and count as 1/3 of your Summer Assignment Test grade (which will also include a calculator section test grade and a noncalculator section test grade, each of which also counting as 1/3 of the Summer Assignment Test grade). You will most likely take the non-calculator section of the Summer Assignment Test on the third day of class and the calculator section on the fourth day of class.
