AP Calculus (ab) Syllabus Stephens HHS 2014/15 Thank you for selecting AP Calculus as one of your courses for next year. You are holding the course description and syllabus for the 2014-2015 class. Should you have had summer homework? NO! Do we hit the ground running? YES! AP Calculus builds on our study of functions. We look at the manner in which they change slope and shape, and we examine the ways in which they sketch out area. We emphasize the interplay between algebraic, numerical, and graphical interpretations and the connections between these different ways of ‘seeing’ mathematics. Our class is based on the guidelines created by the college board and presented in its course description booklet. I’ll attach a copy to our class web page. Past honors work is not a pre-requisite, but students must be prepared to do a great deal of work – mental and written – in and out of the classroom. Calculators: We rely heavily on calculators to explore hypotheses and estimate values. Think of the calculator as a mini lab space for our explorations. Thanks to a generous Hastings Education Foundation grant, the school is able to loan you a computer-algebraic-system (CAS) calculator to everyone in class. That said, we also need to internalize the connections and processes that we study, so we also need to be comfortable working without one. We use the calculator on some – but not all assessments, just as we use them for some, but not all discussions. Getting Help: Calculus is a difficult subject and students should expect to need help now and then throughout the year. Form study groups early and use them often. They are a great way to establish the basics for each topic and to practice with and test each other. You can always talk with me after school (until about 3:15). Unfortunately, my chairmanship duties occasionally make me hard. Don’t panic. Use my email addresses to ask questions: stephensg@hohschools.org and stephensg@verizon.net please, please treat these carefully. I use the school one during the day and the home email at night. As a last resort, just pick up the phone and call me: 478 8667. I can sometimes set you straight in a minute or two, if not, we can arrange a good time to meet the next day. Grades This is not really a class about daily homework. If I give you some, it’s because the work supports something we’re doing. Problem sets are assigned every other week and you work on them at home. These ask for annotated solutions to free response questions. Quizzes are generally 20 – 40 points and often quite difficult. Tests are generally bigger and all the points add up over the quarter. Your grade is simply points received divided by points offered plus a smidgeon for classwork. Everything is on the portal; just stop in if you have questions. Page 1 of 8 AP Calculus: Stephens 2014/15 Resources Our textbook: Finney, Ross L., Franklin D. Demana, Bert K.

We’ll use a web-based graphing program, Desmos (www.desmos.com) to fuss with graphs, as well as GeoGebra, an open source dynamic geometry program that runs installed and streamed. On the school network, we’ll use a different geometry program, Geometer’s Sketchpad. I’ll also share things with you through our schoolwires class page and through our google accounts. Khan academy has pretty good videos, and there are a few websites I really like, such as Paul’s Online Calculus from Paul Dawkins and SOS Math. I’ll send you online now and then to see different approaches and to explore. Did I leave anything out? Questions? Stop by and ask or shoot me an email. The pages that follow detail the flow of topics over the year. You’ll want to add in stuff like breaks and holidays. Page 2 of 8 AP Calculus: Stephens 2014/15 Pre-Season: We have two days. After we take a peek at the syllabus, I’m going to try to convince you that math is all about connections rather than procedures. We’ll start with a story on the first day and look at some experimental data on the second. Week One: The limit. Remember limits from precalc? We’ll review the concept of limit (or introduce it fresh) Explore asymptotes and continuity using a calculator. Develop the concept of the limit using graphical and numerical approaches. Review the Intermediate Value Theorem from PreCalc Honors as a way of reviewing reasoning and deduction. Problem Set assigned: Lab Activity #2 from A Watched Cup Never Cools, Ellen Kamischke (1999: Key Curriculum Press). This lab asks students to explore a limit dynamically in sketchpad and then find it analytically. Take-Home Quiz on “Previous Math” Week Two: Local Linearity The function ‘machine’ helps us determine the position of a point on the graph of a function. How does the concept of local linearity help us understand what that point is ‘doing?’ Use the calculators to zoom in on a specific point on a variety of functions. Use the calculators to manage the tiny ∆y’s and ∆x’s. Discuss, “what is the difference between where a function is and what it is doing?’ Formalize the concept of difference quotients: LDQ, RDQ, SDQ. History Essay/ Class discussion: The role of Newton’s infintesimals. Quiz on Linearity. Lab Activity #2 due. Week Three: Working with data. Back to the experimental data from day 2: When is the ball rolling fastest? What happens at the transition ramp to floor? At what times is the ROC (exactly) 1 foot per second? Is there a new function that describes this data best? Compare the calculator’s estimate of nDeriv as a function to the new function you create for your data. How are they similar/different? Discuss the meaning of the slope or your new slope function for tides. Problem Set assigned: Practice FRQs related to estimating rates. Quiz on estimating rates and extrapolating past and future values. Week Four: Formal definition of the derivative. What is the difference between determining what a function is doing at a point (last week) and creating a new function that does this for all points? Concept: transition from estimates at a point to a formal function for all points. Algebra: practice in manipulating the limit statement to simplify ∆x. Re-connect: does the new (derivative) function produce the same results as our ROC estimates? As our calculator’s nDeriv approximations?
