AP Calculus AB Course Syllabus Math Department E-Mail: Emily.lucas@pikeville.kyschools.us Grade Level: 11-12 Contact Times: 1:15 P.M. – 2:05 P.M. Credit: 1 hour School Phone: 606-432-0185 Fees: None Prerequisite: Algebra I, Algebra II, Geometry, Pre-Calculus Course Description: This course teaches all topics associated with Functions, Graphs, and Limits; Derivatives; and Integrals as delineated in the Calculus AB Topic Outline in the AP Calculus Course Description. Course Design and Philosophy: Students do best when they have an understanding of the conceptual underpinnings of calculus. Rather than making the course a long laundry list of skills that students have to memorize, the “why’ behind the major ideas is stressed. If students can grasp the reasons for an idea or theorem, they can usually figure out how to apply it to the problem at hand. Teaching Strategies: During the first few weeks, extra time is spent familiarizing students with graphing calculators. Students are taught the rule of three: Ideas can be investigated analytically, graphically, and numerically. Students are expected to relate the various representations to each other. The graphing calculator is used to help students develop an intuitive feel for concepts before they are approached through typical algebraic techniques. Finding a root, sketching a function in a specified window, approximating the derivative at a point using numerical methods, approximating the value of a definite integral using numerical methods, and other calculator functions will ultimately be emphasized. It is important for them to understand that graphs and tables are not sufficient to prove an idea. Verification always requires an analytic argument. It is important to maintain a high level of student expectation. Students will rise to the level that is expected of them. A teacher needs to have more confidence in the students than they have in themselves. Communication is stressed as a major goal of the course. Students are expected to explain problems using proper vocabulary and terms. Many times students take the role of teacher in their small groups or upon occasion to the whole class. Communication between classmates is encouraged and facilitated. 1 Resource Materials: Primary Textbook Title: Calculus, 7th edition Author: Larson/Hostetler/Edwards Publisher: Houghton Mifflin Company Copyright: 2002 ISBN: 0-618-14918-X Resource Textbook Title: Calculus, 5th edition Author: James Stewart Publisher: Brooks/Cole Copyright: 2003 ISBN: 0-534-39366-7 Resource Title: Multiple-Choice & Free-Response Questions in Preparation for the AP Calculus (AB) Examination, 7th edition Title: Accompanying Student Solutions Manual, 7th edition Author: David Lederman & Lin McMullin Publisher: D&S Marketing Systems, Inc.

Students will know the definition and properties of a continuous function as they relate to limits and graphical interpretations; explain continuity at a point, and be able to identify functions which are continuous. Students will understand asymptotes in terms of graphical behavior and in terms of limits involving infinity. Students will find horizontal and vertical asymptotes using limits. Students will be able to compare relative magnitudes of functions and their rates of change (for example, contrasting exponential growth, polynomial growth, and logarithmic growth). Students will be able to explain and derive the limit definition of the derivative with the understanding of derivative as an instantaneous rate of change, and explain the relationship between differentiability and continuity. Students will be able to estimate derivatives of functions graphically, numerically, and using a graphing calculator. Students will be able to explain the difference between average and instantaneous rate of change, approximate rates of change from graphs and tables, and sketch a graph of f´(x) given the graph of f(x). Students will be able to use implicit differentiation when applicable, such as the derivative of an inverse function. Students will be able to explain how to find critical points and extreme values, state and apply the Mean Value Theorem. Students will be able to sketch a graph of f(x), given characteristics of f, f´, f´´ (increasing and decreasing behavior of f and the sign of f´; relationship between the concavity of f and the sign of f´´; points of inflection as places where concavity changes). In addition, curve sketching will draw upon the student’s knowledge of domain and range, vertical and horizontal asymptotes, symmetry, continuity and differentiability. Students will be able to use Calculus to solve application problems such as related rates, optimization (absolute and relative extrema), velocity, speed, acceleration, and position. Students will be able to differentiate and integrate basic functions (power, exponential, logarithmic, trigonometric, and inverse trigonometric functions) using rules for the derivative, such as sums, products, quotients, chain, and implicit. Students will understand that rules for differentiation are derived from the limit definition of the derivative. Students will be able to define a definite integral as a limit of Riemann sum using left, right, and midpoint summation. In addition, students will use trapezoidal sums to approximate definite integrals of functions represented algebraically, graphically, and by tables of values. Students will be able to solve separable differential equations and use them in modeling (in particular, studying the equation y´ = ky and exponential growth). Students will be able to interpret differential equations using slope fields and understand the relationship between slope fields and solution curves to differential equations. Students will be able to use the Fundamental Theorem of Calculus to solve Definite Integrals and understand its relationship to rate of change of a quantity over an interval. In addition, students will use the Fundamental Theorem to represent a particular anti-derivative, and the analytical and graphical analysis of functions so defined. 3 Performance Standards and Expectations: (Continued) Students will solve anti-derivatives using substitution of variables (including change of limits for definite integrals) and recognize anti-derivatives that follow directly from derivatives of basic functions. Students will be able to find specific anti-derivatives using initial conditions, including applications to motion along a line. Students will be able to use integrals to find accumulated change, the area of a region, volume of a solid of revolution (Disk, Washer, and Shell method), volume of a solid by known cross section, average value of a function, and the distance of a particle along a line.

Indeterminate Forms and L’Hopital’s Rule Activities: The following sample activities demonstrate ways to help students gain an increased understanding of calculus. Example 1 The “table” feature of the TI graphing calculator can be used to zoom in on a limit numerically. For example, to find x2 lim 2 x2 x 4 we view the values of the function from x-values of 1.5 to 2.5 with an increment step of 0.1. At x = 2 the table records “error” or “not defined.” Students should see that the y-values seem to follow a pattern. Redo the process beginning at 1.9 with a step size of 0.01, and observe that the y-values are converging to 0.25. The process can be repeated with smaller and smaller steps. The limit can also be shown visually by graphing the function in a window that has a pixel step of 0.1. Trace the function beginning at x = 1. Each step shows the corresponding x- and ycoordinates, but at x = 2, the y-coordinate disappears. It “reappears” when the tracing continues at x = 2.1. Students can see graphically that the y-coordinates cluster at about 0.25 as x is near 2. For comparison, do the same exploration with x2 4 lim x 2 x2 This function is also undefined at x = 2, but the y-values do not converge as x approaches 2. Instead, the values “explode”, giving students a numerical look at asymptotic behavior. Example 2 The “Round Barn” assignment that follows is assigned at the beginning of the year. Students are not aware of ways in which calculus could be applied to the problem. Students are 5 reassigned the problem at the end of the school year, but with the charge that they must use calculus in significant ways to justify their arguments. Their final task is to present their justifications to the class and the following scoring criteria sheet is used to assess. Classmates and the teacher fill out the scoring criteria form, complete with comments. Comments are to be constructive criticism. Presenters are given these critiques later and asked to read them looking for themes representing areas of improvement. 6 Agriculture has always played a large part in the history of West Virginia. Round barns, though never quite as common as the standard square or rectangular shaped barns, were seen as a time and money saver. The selling point for the round barn design was the large loft space, which allowed farmers to store hay in the barn, eliminating the cost of building and maintaining outbuildings for hay storage. This also reduced the farmer’s work since they did not need to haul the hay to the barn to feed the livestock. The Hamilton Round Barn, built in 1912 by Amos C. Hamilton as a dairy barn, also incorporates a technology more commonly associated with the Pennsylvania bank barns. It has two main entrances, one on the lower level for livestock and another, accessible by ramp, to the second level where the farmer would store equipment and silage. The above picture and description was taken from the Frontiers to Mountaineers Heritage Tourism brochure on Mountaineer Architecture. There are two statements I would like for you to justify. Statement 1: “Round barns, though never quite as common as the standard square or rectangular shaped barns, were seen as a time and money saver.” Statement 2: “The selling point for the round barn design was the large loft space, which allowed farmers to store hay in the barn.” Task 1: Mathematically support or contradict the claim made by statements 1 and 2 in the brochure. (Note: Hay could have been stored in square and rectangular barn lofts as well. So, statement 2 implies that the loft space of the round barn is more efficient.) Follow-up question: Would the way hay is stored today, as compared to 1912, make the round barn more attractive or less attractive? Justify your answer mathematically. Task 2: What other shapes might barns be built in? Compare at least two other shapes to a square, rectangle, and circle supporting claims of comparison mathematically. 7 The Round Barn Scoring Criteria 1=strongly agree 2=agree 3=average performance 4=disagree 5=strongly disagree 1.)
