1 AP Calculus AB Syllabus Course Description: This is a college level course covering derivatives, integrals, limits, applications and modeling of these topics. Course Objectives: The objectives of this course are: To work with functions represented in a variety of ways: graphically, analytically, numerically. They should understand the relationship of each way. To understand the meaning of the derivative in terms of a rate of change and local linear approximation and should be able to use derivatives to solve several problems To understand the meaning of a definite integral as both a limit of a Riemann sums and the net accumulation of a rate of change and use integrals to solve several problems To know the relationship between a derivative and a definite integral dealing with the Fundamental Theorem of Calculus. To be able to use a graphing calculator to plot a graph of a function within an arbitrary viewing window, find zeros of a function, numerical calculate the derivative of a function, and numerically calculate the value of a definite integral. Course Expectations: To inquire about material and concepts that may not be clear To strive to apply knowledge from previous courses in a new way To conceptualize the calculus curriculum and apply knowledge To communicate mathematics both orally and in well written sentences. Teaching Strategies Some examples are imbedded in the curriculum using parenthesis. Students must write out solutions to application problems with logically explanations to this. They must interpret graphs and tables. Use mirroring techniques that are given in the AP released calculus exams to show how to communicate mathematically and what an acceptable answer looks like. Test and quizzes are given over skills and applications. Students are assigned problems in their text, pre-made handouts, calculator labs, board problems, and released items. Overheard projector attached to a computer is used to show graphical representation, especially in area of revolution to create volume and solids of a known cross section. Course Outline: I.
