2 Course Overview This course will cover all sections outlined in the AP Calculus AB Course Description and is intended to expand the student s comprehension of the concepts of calculus, its ideas, its methods and applications. The primary textbook is Calculus of a Single Variable, 8 th edition by Larson, Hostler and Edwards. This class of calculus is taught as a whole subject and does not diverge into other mathematical ideas. The instructive methodology of this course will be done numerically, graphically, analytically and verbally. The main objectives in teaching this course are to make it possible for students to receive a deep footing in calculus skills equal in content to the best collegiate courses and to provide students with the tools needed to succeed in taking the AP Calculus Test. The following outline is our AP Calculus AB course, complete with a brief description of each chapter, a concise account of each section, and a timeline. This course will educate students in all topics associated with graphs, functions, limits, differentiation and integration as defined in the AB Calculus Topic Outline in the AP Calculus Course Description.

Mathematics of change. f ( c+ Δx) f( c) The Tangent Line Problem. msec = Δx The Area Problem. To find the area under the curve. 1.2 Find Limits Graphically and Numerically 2 This section shows how limits can be understood graphically, numerically and how they can fail to exist. Also included in this understanding are infinite and finite limits and their relationship to the graph of the function along with horizontal and vertical asymptotes. The formal definition of ε δ is also given because of its important fundamental idea Introduction to Limits; lim f ( x) = L x c Limits that fail to exist; a) f(x) approaches a different number from the right side of c than it approaches from the left side. b) f(x ) increases or decreases without bound as x approaches c. c) f(x) oscillates between two fixed values as x approaches c Definition of a Limit, ε δ definition of a limit. Let f be a function defined on (a,b) containing c and let L be a real number. The statement lim f ( x) = L means that for each ε > 0 there exist a δ > 0 such that if 0 < x c x c < δ then f ( x) L < ε 1.3 Evaluating Limits Analytically 2 Limits are taken to the next step of being solved analytically along with much emphasis placed on the indeterminate forms of solution.

Also this chapter explains how the use of derivatives determines an instantaneous rate of change and the velocity function. Finally, the remainder of this chapter shows helpful rules that need to be memorized and how to find the derivative of a function which will be tested on the AP exam. 2.1 The Derivative and the Tangent Line Problem 5 One of the prime ideas of the study of calculus begins by observing the slope of the secant line and how, as it moves closer to the tangent line, it is defined as the derivative of the function at the point of tangency. This new function, described as the derivative at a point, is the slope of the tangent line at that point The Tangent line problem. Definition of Tangent Line with Slope m; If f is defined on an open interval Δ y f( c+δx) f( c) containing c, and if the limit lim = lim = m exist, then the line Δx 0Δx Δx 0 Δx passing through (c,f(c)) with slope m is the tangent line to the graph of f at the point (c,f(c) The Derivative of a Function, The derivative of f at x is given by f ( x+δx) f( x) f ( x) = lim, provided the limit exists. Δx 0 Δx

6 2.1.3 Differentiability Implies Continuity, Theorem Differentiation Rules and Rates of Change 4 This section reveals much usefulness of differentiation by applying to the principles of instantaneous rate of change of an object in motion and finding velocity which is the derivative of the position function The Constant Rule, Theorem The Power Rule, Theorem The Constant Multiple Rule, Theorem The Sum and Difference Rules, Theorem Derivative of Sine and Cosine Functions, Theorem Rates of Change change in distance Δs Average velocity: = change in time Δ t st ( + Δt) st ( ) Velocity function: vt () = lim = s () t Δ t o Δt 1 2 Position function: st () = gt + vt 0 + s The Product and Quotient Rule, and to rewrite functions. 3 The concepts of derivatives are made easier by mastering the rules of this section along with higher order derivatives and their notations. Building from the previous section, the derivative of velocity then is found to be the function for acceleration The Product Rule, Theorem The Quotient Rule, Theorem Derivatives of Trigonometric Functions, Theorem 2.9 dy d Higher Order Derivatives, y, f ( x),, [ f( x) ], Dx [ y] dx dx Acceleration Function: at () = v () t = s () t 2.4 The Chain Rule 3 The Chain Rule along with the General Power Rule are very powerful rules used as building blocks of finding derivatives of functions, which are weighed heavily on the AP exam. All the rules of derivatives learned up to this point and in this section should be memorized The Chain Rule, Theorem The General Power Rule, Theorem Simplifying Derivatives Trigonometric Functions and the Chain Rule 2.5 Implicit Differentiation 3 When it is necessary to find the derivative of a relationship that can not be written as a function or it is not possible to solve analytically, isolate y as a function of x, then the concept of implicit differentiation is used along with the chain rule Implicit and Explicit Functions Implicit Differentiations, follow guidelines; 1) Differentiate both sides of the equation with respect to x.

7 2) Collect all terms involving dy/dx on the left side of the equation and move all other terms to the right side of the equation. 3) Factor dy/dx out of the left side of the equation. 4) Solve for dy/dx by dividing both sides of the equation by the left-hand factor that does not contain dy/dx. 2.6 Related Rates 3 When a relationship involves one quantity that is dependent on more than one other variable, then a methodical approach using related rates is needed. Much detail is stressed on setting up each question Finding Related Rates; Guidelines for Solving Related Rates 1) Identify all given quantities and quantities to be determined. 2) Write an equation involving the variables whose rates of change either are given or are to be determined. 3) Using the chain rule, implicitly differentiate both sides of the equation with respect to time t. 4) After completing step 3, substitute into the resulting equation all known values for the variables and their rate of change. Then solve for the required rate of change. Review and Assessment 3 Chapter 3 3 Applications of Differentiation Days: 29 This chapter puts derivatives to work by making a connection between using the first and second derivatives and extremes. The first part of this chapter deals with the first and second derivatives and how the function acts on the plane. The characteristics of limits at infinity are graphically observed and then the applications of derivative through optimization problems are applied. Newton s Method is touched upon and then the last section deals with differentials and approximating the y-value of a function near a known point. 3.1 Extrema on an Interval 3 The valuable concepts of extrema and the Extreme Value Theorem on the open and closed interval are covered in detail along with finding the maximum and minimums. Critical values of a function are also discussed as a valuable procedure for finding relative extrema Extrema of a Function Definition of Extrema: Let f be defined on the interval I containing c. 1) f(x) is the minimum of f on I if f(c) f(x) for all x in I. 2) f(c) is the maximum of f on I if f(c) f(x) for all x in I. The minimum and maximum of a function on an interval are the extreme values, or extrema, of the function on the interval. The minimum and maximum of a function on an interval are also called the absolute minimum and absolute maximum on I.

8 3.1.2 The Extreme Value Theorem, Theorem Definition of relative Extrema; 1) If there is an open interval containing c on which f(c) is a maximum, then f(c) is called a relative maximum of f. 2) If there is an open interval containing c on which f(c) is a minimum, then f(c) is called a relative minimum of f. The plural of relative maximum is relative maxima, and the plural of relative minimum is relative minima Definition of Critical Number. Let f be defined at c. If f ( c) = 0 or if f ( c) is undefined at c, then c is a critical number of f Relative Extrema Occur Only at Critical Numbers. Theorem Finding Extrema on a Closed Interval. Guidelines; To find the extrema of a continuous function f on a closed interval [a,b], use the following steps. 1) Find the critical numbers of f in (a,b). 2) Evaluate f at each critical numbers in (a,b). 3) Evaluate f at each endpoint of [a,b]. 4) The least of these values is the minimum. The greatest is the maximum. 3.2 Rolle s Theorem and the Mean Value Theorem 3 The graphical interpretation from the Rolle s and the Mean Value Theorem will help students understand that on the function there is some point where the tangent line is parallel to the line connecting the endpoints of the interval. Show that the slope of the tangent line applying the Rolle s Theorem is equal zero Rolle s Theorem, Theorem Mean Value Theorem, Theorem Increasing & Decreasing Functions and the First Derivative Test 2 This section shows the function increasing and decreasing on the open and closed interval using its derivative. Students will learn to find relative extrema and the change of sign at the critical point. It is also stressed that if the derivative changes from positive to negative it indicates a local maximum, and if it changes from negative to positive indicates a minimum Test for Increasing and Decreasing Functions, Theorem The First Derivative Test, Theorem Concavity and the Second Derivative Test 2 Students will learn that concavity relates to the rate of change of the function. When concavity changes, given by the second derivative, students will see this gives us the point of inflection. Finally the Second derivative Test is an alternate to finding the critical points by finding the maximum or minimum Concavity: Test for Concavity, Theorem Point of Inflection, Theorem Second Derivative Test, theorem Limits at Infinity 2 This section is very important for students as it shows what the function is doing at both extremes at infinity. Furthermore the section shows what type of functions have horizontal asymptotes and show easy guidelines to find them Definition of Limits at Infinity; Let L be a real number.

9 1) The statement lim f ( x) = L means that for each ε > 0 there exist an x M > 0 such that f ( x) L < ε whenever x > M. 2) The statement lim f ( x) = L means that for each ε > 0 there exist an x N < 0 such that f ( x) L < ε whenever x < N Definition of Horizontal Asymptote; he line y = L is a horizontal asymptote of the graph of f if lim f ( x) = L or lim f ( x) = L. x x Limits of infinity, Theorem Summary of Curve Sketching 2 This section requires students to sketch and define the characteristics of a function using a full analysis using the following techniques and first and second derivative tests Review the following techniques; 1) x-intercept and y-intercept 2) Symmetry 3) Domain and range 4) Continuity 5) Vertical asymptotes 6) Differentiability 7) Relative Extrema 8) Concavity 9) Points of Inflection 10) Horizontal Asymptotes Guidelines for Analyzing the graph of a function; 1) Determine the domain and range of the function. 2) Determine the intercepts and asymptotes of the graph. 3) Locate the x-values for which f ( x) and f ( x) are either zero or undefined. Use the results to determine relative extrema and the points of inflection. Review and Assessment Optimization Problems 5 Students will learn that a common application of calculus entails the determination of minimum and maximum values. The focus is to identify and isolate the function to be optimized Applied Minimum and Maximum Problems, Strategies; 1) Assign symbols to all given quantities and quantities to be determined. When feasible make a sketch. 2) Write a primary equation for the quantity that is to be maximized or minimized. 3) Reduce the primary equation to one having a single independent variable. This may involve the use of secondary equation relating the independent variables of the primary equations. 4) Determine the domain of the primary equation. That is, determine the values for which the stated problem makes sense.

10 5) Determine the desired maximum or minimum value by using the second derivative test. 3.8 Newton s Method 1 This section is used as an alternative form for approximating the real zeros of a function Newton s Method for Approximating the Zeros of a Function; Let f(c) = 0, where f is differentiable on an open interval containing c. Then, to approximate c, use the following steps. 1) Make an initial estimate x 1 that is close to c. A graph is helpful. 2) Determine a new approximation f ( xn ) x n 1 x + n. f ( xn ) 3) If xn x n + 1 is within the desired accuracy, let x n + 1 serve as the final approximation. Otherwise, return to step 2 and calculate a new approximation. 3.9 Differentials 3 Students will learn the concept of a tangent line approximation also known as linearization of a function. This sets students up to learn about slope fields and the family of functions. Also students will learn about finding propagated error from the difference between the measurement error and measured value Linear Approximation: For dx = Δx is sufficiently small, the differential dy is a good approximation to Δy, in that dy differs from Δy by small percentage of dx. That is Δy dy if Δx Differentials: Let y = f(x) represent a function that is differentiable in an open interval containing x. The differential of x (denoted by Δx) is any nonzero real number. The differential of y (denoted by dy) is dy = f (x)dx Error Propagation = f(x + Δ) f(x) = Δy Differentials can be used to approximate function values. For the function given by y = f(x), use the formula f ( x + Δx) f ( x) + dy = f ( x) + f ( x) dx Business and Economics Applications, Terms and Formulas: (supplementation from 6 th edition of Larson, Hostetler and Edwards) Basic Terms Basic Formula x is the number of units produced or sold p is the price per unit R is the total revenue from selling x units R = xp C is the total cost of producing x units C is the average cost per unit C C = x P is the total profit from selling x units P = R C The break even point is the number of units for which R = C Marginals. dr = (Marginal revenue) (extra revenue from selling one additional unit) dx dc = (Marginal cost) (extra cost of producing one additional unit) dx dp = (Marginal profit) (extra profit from selling one additional unit) dx Review and Assessment 3

Student Evaluation Four nine week grades consist of compiling scores from homework assignments, quizzes, group projects, and chapter tests. Most assignments come from the textbook exercises of each section. The text book has a plethora of questions and problems to choose from for daily assignments. The instructor resource guide provides a host of testing options. A specific number of tests are subject to change based on time constraints, chapter content and as deemed necessary by the instructor. All nine weeks represent 90 percent of the student s grade and the final test represents 10 percent of the grade. Homework is checked at random and assessed on completeness. Quizzes will occur during every section and are assessed ten to thirty percent of a test grade. Tests will have either multiple-choice or completion format and students can use a calculator for most work. Previous and simulated AP Exams will be experienced during the year allowing for additional experience and assessment.
