If you are proficient in math, AP Calculus AB may be the high school course for you. This Advanced Placement track follows precalculus and may be your first introduction to calculus. It opens the door to many other AP math classes and tests. The full-year course includes content that many students don’t see until attending a college or university. You could receive college credit or have a placement advantage for successfully completing the course.

The general equivalent of a semester of college calculus, AP Calculus AB focuses mainly on differentiation and integration. It includes lots of graphical analysis; some components you’ll encounter are asymptotes and limits, derivatives, and integrals. By the time you start the course, you should have already mastered algebra, geometry, and trigonometry. The goals of the course are for you to understand how to work with functions, the meaning of a derivative related to rate of change and linear approximation, and the limit and change of a definite integral. Written and verbal communication, technology, and reasoning are essential skills that enable you to succeed in AP Calculus AB.

The AP Calculus AB Exam is about three hours and fifteen minutes. Its two parts each account for 50 percent of the final grade. The first section consists of 45 multiple-choice questions. You have one hour and forty-five minutes to work on Parts A and B. In Part A, there are 28 questions, and Part B has 17 questions. The main difference between the two is you cannot use a calculator for the first part, but a graphing calculator is permitted for the second part. Section 2 is free response and has six questions, which you have an hour and thirty minutes to complete. Part A of Section 2 has two problems, which you can use a graphing calculator to answer. The four problems of Section 2’s Part B must be answered on your own, without a calculator.

Generally, the AP Calculus AB curriculum starts with functions, graphs, and limits. You will need to master analyzing data on graphs before continuing, and will have to predict and explain the behavior of a function. The limits of functions are covered next. To calculate limits, you’ll need to apply the algebra learned in previous math courses, and graphs and tabulated data will be used to estimate the limits you are provided with. Other topics include asymptotic and unbounded behavior. Asymptotes on a graph indicate the infinite properties of limits and the rates of change of functions, accounting for exponential growth, logarithmic growth, and polynomial growth. Continuity is another important topic, in terms of limits and identifying the graphs for continuous functions.

You’ll also be introduced to the concept of the derivative and its relation to rate of change. The graphical, numerical, and analytical properties of derivatives will come into play. As you move forward, you will have to understand the derivative at a point, applying this to concepts such as the slope of a curve, for example. Calculations that will have to be made include approximating rate of change and calculating a tangent line to a curve. Working with a derivative of a function, more graphs will be used, and you’ll have to understand relationships between increasing and decreasing functions, denoted as the symbols f and f’. Concepts such as the Mean Value Theorem will be applied. You will also encounter equations with derivatives and translate verbal descriptions into such equations.

Other AP Calculus AB topics include second derivatives, which have traits such as concavity, and applications of derivatives. At this point, you will be called on to analyze curves, model rates of change, and find a derivative of an inverse function. Other aspects include absolute and local extrema. Geometric interpretation of differential equations is part of this stage of the course, along with computation of derivatives with functions such as exponential, power, trigonometric, inverse trigonometric, and logarithmic functions. Moving forward will also require understanding the chain rule and implicit differentiation.

Next, you will work with integrals. This section of the curriculum involves the properties of definite integrals and the applications of integrals in physics, biology, and economics. You will have to approximate Riemann sums, and use a definite integral to represent their limits. The Fundamental Theorem of Calculus comes next. With this, you’ll be able to evaluate definite integrals and represent antiderivatives. The theorem effectively links the concept of a function’s derivative with that of its integral. Its first part says the definite integration of a function, related to the antiderivative, can be reversed through differentiation. In the second part, the idea is that an infinite number of antiderivatives can be used to calculate a definite integral of a function. Sound hard? First understand the theorem simplifies the process of computing definite integrals, and is thus a key concept to consider as you move through AP Calculus AB.

The techniques and applications of antidifferentiation will be introduced next and, using Riemann sums, numerical approximations of definite integrals will have to be made. Techniques include working with antiderivatives following derivatives of functions, and by substitution of variables. Calculations will apply left, right, and midpoint evaluation points, plus trapezoidal sums to approximate the definite integrals of functions. Graphical, tabulated, and algebraic data are used to do this.

Yet another important AP Calculus AB topic is L’Hôpital’s rule, which provides further insight into derivatives, helping evaluate them with indeterminate forms. It also works with one-sided limits and involves the functions of f and g.

The principles of calculus are increasingly taking a role in students’ lives. More are taking AP Calculus exams; the number of test takers has increased to over 250,000 per year. The curriculum of AP Calculus AB is more advanced than what most high schoolers are used to, but if you meet the qualifications and prerequisites, it may be something to seriously consider. There are many complex topics to understand, but the benefits to the hard work can last through college and beyond. Taking on the challenge now may help set you apart in the future.
