19. AP Calculus Syllabus Analysis of graphs With the aid of technology, graphs of functions are often easy to produce. The emphasis is on the interplay between the geometric and analytic information and on the use of calculus both to predict and to explain the observed local and global behavior of a function. Derivative as a function Corresponding characteristics of graphs of ƒ and ƒ’ Relationship between the increasing and decreasing behavior of ƒ and the sign of ƒ’ Applications of derivatives Optimization, both absolute (global) and relative (local) extrema Modeling rates of change, including related rates problems Interpretation of the derivative as a rate of change in varied applied contexts, including velocity, speed, and acceleration Interpretations and properties of definite integrals Definite integral of the rate of change of a quantity over an interval interpreted as the change of the quantity over the interval Applications of integrals Appropriate integrals are used in a variety of applications to model physical, biological, or economic situations. Although only a sampling of applications can be included in any specific course, students should be able to adapt their knowledge and techniques to solve other similar application problems. Whatever applications are chosen, the emphasis is on using the method of setting up an approximating Riemann sum and representing its limit as a definite integral. To provide a common foundation, specific applications should include finding the area of a region, the volume of a solid with known cross sections, the average value of a function, the distance traveled by a particle along a line, and accumulated change from a rate of change. Applications of antidifferentiation Finding specific antiderivatives using initial conditions, including applications to motion along a line
