1 AP Calculus Review Assignment Answer Sheet 1 Name: Date: Per. Harton Spring Break Packet 015 This is an AP Calc Review packet. As we get closer to the eam, it is time to start reviewing old concepts. Use the answer sheet provided for all answers and then when appropriate show work. Assignment: First 60 problems Due Date: April 14, 015 Late work will receive reduced credit. This assignment will be graded. Therefore, this is a project. A lot of you will skip the reading material and see if you can work the problems. If you can work the problems, then do, but, I do you want you to read the reading material. This is an important part of the review, going over old concepts.

7 AP Review Packet: 7 Essential AP Calculus Concepts 1. Limits A. Finite Limits - Try direct substitutions first, if that fails, try to factor or use L Hopital s Rule. 1. lim lim 4. lim sin 4. lim cos lim 0 B. Limits to Infinity - These are also called horizontal asymptotes. If the degree of the numerator is smaller than that of the denominator, then the lim 0. If the degree of the numerator is equal to that of the denominator, then the lead coefficient lim. lead coefficient If the degree of the numerator is larger than that of the denominator, then the lim Does Not Eist Be careful of limits going to. Sometimes they don t follow the patterns above! When you have e, remember that it dominates any polynomial and you need to look at find a simple left-end and right-end model to evaluate. 6. lim lim 8. lim lim lim e lim e 4 C. Limits from a Picture Look at the graph and find the intended height of the function.
