Advanced Placement Calculus AB Syllabus Angie Avery Angela.Avery@vansd.org Note from the Instructor It is my hope that each of you want to learn as much as you can about calculus. Mathematicians have been responsible for many great developments throughout history. Much of our understanding of the universe is a direct result of the contributions of mathematicians. I hope you learn to view math as more than just numbers, variables, processes, and algorithms. I hope you learn to apply your mathematical understandings to help you create a better understanding of the mathematical nature of our lives. Course Objectives By successfully completing this course, you will be able to do the following Work with functions represented graphically, numerically, analytically, or verbally, and understand the connections among these representations. Understand the meaning of a derivative in terms of a rate of change and local linear approximation and use derivatives to solve a variety of problems. Understand the meaning of the definite integral both as a limit of Riemann sums and as a net accumulation of a rate of change, and understand the relationship between the derivative and integral. Represent differential equations with slope fields and solve separable differential equations analytically. Model problem situations with functions, differential equations, or integrals, and communicate both orally and in written form. Use technology to help solve problems, interpret results, and verify conclusions. Determine the reasonableness of solutions, including sign, size, relative accuracy, and units of measurement. Develop an appreciation of calculus as a coherent body of knowledge and as a human accomplishment. Technology Requirement A Texas Instruments 84 Plus graphing calculator will be used in class regularly. I would recommend purchasing a TI-84 Plus if you do not already own a graphing calculator. There will be a classroom set of TI84 Plus calculators as well as some available for extended checkout from the media center. Calculators will be used for the following: Plotting the graph of a function within an arbitrary viewing window Finding the zeros of functions (solving equations numerically) Numerically calculating the derivative of a function Numerically calculating the value of a definite integral Viewing slope fields for differential equations Textbook Finney, Demana, Waits and Kennedy. Calculus – Graphical, Numerical, Algebraic. Third edition. Pearson, Prentice Hall, 2007. This textbook will be our primary resource. Students will benefit from reading each section. The text contains a number of interesting explorations and I encourage students to work through these together in order to construct understanding. A Balanced Approach This course will emphasize a “Rule of Four” technique: analytic/algebraic, numerical, graphical, and verbal methods of representing problems. Students must value each method, understand how they are connected to a given problem, and learn how to choose the most appropriate for a given problem. With this balanced approach, students will be expected to do the following: Obtain solutions algebraically or analytically Support answers graphically or numerically with technology Interpret the result in the original problem context Course Outline – Tentative Timeline Unit 1: Limits and Continuity (3-4 weeks) A. Rates of Change a. Average Speed b. Instantaneous Speed B. Limits at a Point a. One-sided Limits b. Two-sided Limits c. Sandwich Theorem i. In order to help tie the graphical implications of the Sandwich Theorem to the analytical applications of it, students will conduct an explorations where they graph the following equations: y1=x^2, y2=-x^2, and y3=sin(1/x). They then attempt to “see” the limit as x approaches 0 of x^2*sin(1/x). C. Limits involving Infinity a. Asymptotic behavior i. Horizontal ii. Vertical b. End behavior models c. Properties of Limits – algebraic analysis d. Visualizing Limits – graphical analysis D. Continuity a. Continuity at a point b. Continuous functions c. Discontinuous functions i. Removable discontinuity 1. Table groups conduct a tabular investigation of the limit as x approaches 1 of f(x) = (x^2 – 7x – 6)/(x – 1). Then the same group conducts an analytic investigation of the same function. Students in the group will then draw conclusions based on their observations. Finally, students will use their graphing calculators to graph the function and discuss, as a class, whether or not their table’s conclusions were verified or contradicted. ii. Jump discontinuity iii. Infinite discontinuity E. Rates of Change and Tangent Lines a. Average rate of change b. Tangent line to a curve c. Slope of a curve – algebraically and graphically d.

Students play a matching game with laminated cards which represent functions in 4 ways: a graph of the function, a graph of the derivative, a written description of the function, and a written description of the derivative. D. Optimization Problems E. Linearization Models a. Local Linearization b. Tangent Line Approximations c. Differentials F. Related Rates Unit 4: The Definite Integral (3-4 weeks) A. Approximating Area a. Riemann Sums i. LRAM ii. RRAM iii. MRAM iv. Trapezoidal sums 1. Students are given a program to input into their graphing calculators which calculates the trapezoidal sums for trapezoids of equal width. Students are encouraged to think about altering the program to calculate rectangular sums. b. Definite Integrals 1. Each student is asked to draw a linear function of their choosing. Then they are asked to use known geometric methods to calculate the definite integral over a given interval. Students then share their work with their tablemates. c.

Projects designed to incorporate course curriculum Research projects on the historical development of mathematics Advanced Integration College placement exams/ College Math Requirements Grading Grades will include, but not limited to, the following: tests, quizzes, in-class activities, homework assignments, projects and classroom participation. Homework (10%) – assigned almost daily and is due at the beginning of the period the next time our class meets. Assignments are graded based on your effort – If you legitimately attempt every problem, show your work, and follow all directions you’ll receive full credit. Late work is only accepted with a pass (2 per semester). Quizzes (25%) – As long as we are covering new material, there will frequent quizzes, typically on Monday. Quiz questions may be selected directly from problems covered in class (warm-ups, notes, homework). The questions can come from any chapter, not just the chapter we are currently studying. Quizzes may be timed. If you are absent for a quiz, you will take a similar quiz the day you return to class. If the questions are not directly from questions covered in class, you will have the opportunity to reflect for up to ½ credit back (see reflection process below). If questions come directly from questions covered in class there will be no retakes or reflections. The final project after the AP exam will also count as a quiz. It will have a large impact on your grade as we will have fewer quizzes during the 2nd semester. Tests (65%) – Tests will be divided into AP concepts covered in a particular chapter. This means that when you receive your results to a test, you will be able to identify how you performed on each concept separately. If you do not score well on a particular section, you may retake that section. Prior to retake, you will be required to complete a reflection on the entire section. The reflection needs to be stapled to the front of your test and will serve as your ticket into retake. No reflection, no retake. I will set a time frame for retakes (usually around 2 weeks). I will expect all students that receive less than a 70% to retake. Reflection Process – Complete on a separate piece of paper and staple to the front of your original quiz. Use complete sentences and be specific (you will not receive full credit unless you do). 1. Identify the concept missed for each incorrect problem. 2. Explain what you misunderstood about the concept or what was incorrect with your original work. 3. Redo the problem completely, showing ALL work.
