Name: Precalculus Teacher: AP CALCULUS AB ~ (Σer) ( Force Distance) and ( L, L,...) of Topical Understandings ~ As instructors of AP Calculus, we have etremely high epectations of students taking our courses. As stated in the district program planning guide, we epect 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 epect you stay current on your skills as well as improve upon them. Therefore, this packet is a requirement for Calculus AB. 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 50 questions you must complete. SHOW ALL WORK ON THE FOLLOWING PAGES. Please include all the steps used to answer each question. Your work should lead to the correct answer. Please circle or bo 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 eplanations. 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 synta or keystrokes. You must be familiar with certain built-in calculator functions such as finding maimum and minimum values, intersection points, and zeros of a function. We epect 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 Limits of Functions Prove Trig Identities Graphing Piecewise Functions Graphing, simplifying epressions, and solving equations of the following types: Trigonometric, rational, logarithmic, eponential, Polynomial/Power, Radical.
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.
