Name: Previous Math Teacher: AP CALCULUS BC ~ (er) ( Force Distance) and ( L1,L,...) of Topical Understandings ~ As instructors of AP Calculus, we have extremely high expectations of students taking our courses. As stated in the district program planning guide, we expect a certain level of independence to be demonstrated by anyone taking AP Calculus. Your first opportunity to demonstrate your capabilities and resourcefulness to us is through this summer work packet. We expect you stay current on your skills as well as improve upon them. Therefore, this packet is a requirement Calculus BC. It will be your first major grade of the new school year. SHOW US YOUR BEST WORK. It needs to be completed when handed in on the first day of class. Requirements The following are guidelines for completing the summer work packet There are 66 questions you must complete. Please do all your work in this packet. You must show us all of your quality work. Please include all the steps used to answer each question. Your work should lead to the correct answer. Please circle or box each answer!! Be sure all problems neatly organized, and all writing is legible. If you have trouble answering any question, be resourceful. This might include looking back to your notes from previous years or even finding a book or website with formulas or explanations. In the event that you are unsure how to perform functions on your calculator, you may need to read through your calculator manual to understand the necessary syntax or keystrokes. You must be familiar with certain built-in calculator functions such as finding maximum and minimum values, intersection points, and zeros of a function. You will also need to be able to do regression analysis on your calculators. We expect you to come in with certain understandings that are prerequisite to Calculus. A list of these topical understandings can be found below. Please be familiar with all of these and ready to apply them to a higher level. Topical understandings within summer work Factoring Conics Limits of Functions Prove Trig Identities Graphing Piecewise Functions Regression Analysis Graphing, simplifying expressions, and solving equations of the following types: Trigonometric, rational, logarithmic, exponential, Polynomial/Power, Radical, Polar, and Parametric.
Finally, we suggest not waiting until the last two weeks of summer to begin on this packet. If you spread it out, you will most likely retain the information much better. Once again this is due, completed with quality, on the first day of class, and it counts as a grade. It is your ticket into the class. Best of luck and if you have any questions, feel free to contact us.
