OBJECTIVES
These objectives are taken from the 2012 College Board Calculus Course Description.
I. Functions, Graphs, and Limits
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.
Limits of functions (including one-sided limits)
- An intuitive understanding of the limiting process.
- Calculating limits using algebra.
- Estimating limits from graphs or tables of data.
Asymptotic and unbounded behavior
- Understanding asymptotes in terms of graphical behavior.
- Describing asymptotic behavior in terms of limits involving infinity.
- Comparing relative magnitudes of functions and their rates of change (for example, contrasting exponential growth,
polynomial growth, and logarithmic growth).
Continuity as a property of functions
- An intuitive understanding of continuity. (The function values can be made as close as desired by taking sufficiently close values of the domain.)
- Understanding continuity in terms of limits.
- Geometric understanding of graphs of continuous functions (Intermediate Value Theorem and Extreme Value Theorem).
- Parametric, polar, and vector functions. The analysis of planar curves includes those given in parametric form, polar form,
and vector form.
II. Derivatives
Concept of the derivative
- Derivative presented graphically, numerically, and analytically.
- Derivative interpreted as an instantaneous rate of change.
- Derivative defined as the limit of the difference quotient.
- Relationship between differentiability and continuity.
Derivative at a point
- Slope of a curve at a point. Examples are emphasized, including points at which there are vertical tangents and points at which there are no tangents.
- Tangent line to a curve at a point and local linear approximation.
- Instantaneous rate of change as the limit of average rate of change.
- Approximate rate of change from graphs and tables of values.
Derivative as a function
- Corresponding characteristics of graphs of ƒ and ƒ•.
- Relationship between the increasing and decreasing behavior of ƒ and the sign ofƒ•.

Second derivatives
- Corresponding characteristics of the graphs of ƒ, ƒ•, and ƒ •.
- Relationship between the concavity of ƒ and the sign of ƒ •.
- Points of inflection as places where concavity changes.
Assignment:
Through exploration students will investigate critical points both numerically and graphically. Students will then verbalize their findings, describing when a point will be a maximum, minimum or point of inflection.
Applications of derivatives
- Analysis of curves, including the notions of monotonicity and concavity.
- Analysis of planar curves given in parametric form, polar form, and vector form, including velocity and acceleration.
- Optimization, both absolute (global) and relative (local) extrema.
- Modeling rates of change, including related rates problems.
- Use of implicit differentiation to find the derivative of an inverse function.
- Interpretation of the derivative as a rate of change in varied applied contexts, including velocity, speed, and acceleration.
- Geometric interpretation of differential equations via slope fields and the relationship between slope fields and solution curves for differential equations.
- Numerical solution of differential equations using Euler’s method.
- L’Hospital’s Rule, including its use in determining limits and convergence of improper
integrals and series.
Assignment:
This assignment uses a graphical, numerical and analytic approach to help students to develop an understanding of the relationship between position, velocity and acceleration. Students will learn to reason from tables and graphs and to communicate the relationships using correct language and notation.
Computation of derivatives

Reasoning from Tabular Data
Students analyze data from a table. Students will use data to estimate rates or change, net changeand average value from values of functions given in the table. They will need to use a variety of methods to find derivatives and integrals as they relate to real world applications.
Assignment:
Students Discover the First and Second Fundamental Theorems of Calculus through graphical exploration.
Assignment:
Students discover and explore Second Fundamental Theorem of Calculus. Students then use theorem toanalyze the F(x) from the graph of the derivative of the function f.
III. Integrals
Interpretations and properties of definite integrals
- Definite integral as a limit of Riemann sums.
- Definite integral of the rate of change of a quantity over an interval interpreted as the change of the quantity over the interval:
- Basic properties of definite integrals (examples include additivity and linearity).
- 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 (including a region bounded by polar curves), the volume of a solid with known cross sections, the average value of a function, the distance traveled by a particle along a line, the length of a curve (including a curve given in parametric form), and accumulated change from a rate of change.
Fundamental Theorem of Calculus
- Use of the Fundamental Theorem to evaluate definite integrals.
- Use of the Fundamental Theorem to represent a particular antiderivative, and the analytical and graphical analysis of functions so defined.
Techniques of antidifferentiation
- Antiderivatives following directly from derivatives of basic functions.
- Antiderivatives by substitution of variables (including change of limits for
definite integrals), parts, and simple partial fractions (nonrepeating linear factors only). - Improper integrals (as limits of definite integrals).
Applications of antidifferentiation
- Finding specific antiderivatives using initial conditions, including applications to motion along a line.
- Solving separable differential equations and using them in modeling (including the study of the equation y• = ky and exponential growth). + Solving logistic differential equations and using them in modeling.
Numerical approximations to definite integrals. Use of Riemann sums (using left, right, and midpoint evaluation points) and trapezoidal sums to approximate definite integrals of functions represented algebraically, graphically, and by tables of values
ASSESSMENTS
Students will be expected to complete sample problems in each unit as practice for unit tests. Unit tests include multiple-choice and free-response questions from AP Released Exams. Students will be asked to periodically meet with the instructor in the instructor’s chat room to review unit tests and discuss the scoring guidelines. In addition to practice problems and unit tests, students will be asked to complete activities requiring use of graphing calculators and written justifications of their solutions. Sample activities include estimating the limit from a graph and comparing to the numerical computation of the limit, performing differentiation and integration, calculate definite integrals and verify properties of functions. Grades will be determined by student participation in completing practice problems and graded activities as well as by unit test scores.
