What’s a discontinuity? Any point at which a function fails to be continuous is called a discontinuity. In fact, there are various types of discontinuities, which we hope to explain in this review article. Points of Discontinuity The definition of discontinuity is very simple. A function is discontinuous at a point x = a if […]

You know you’ll have to know your derivatives inside and out in order to score high on the AP Calculus exam. But what are the most common derivatives you’ll see on the test? In this short article, we’ll let you in on the secret! Know the Basics First of all, it’s very important to have […]

The disk and washer methods are useful for finding volumes of solids of revolution. In this article, we’ll review the methods and work out a number of example problems. By the end, you’ll be prepared for any disk and washer methods problems you encounter on the AP Calculus AB/BC exam! Solids of Revolution The disk […]

The Ratio and Root Tests are indispensable tools for finding out whether a series converges or diverges. These tests also play a large role in determining the radius and interval of convergence for a series of functions. In this article, we will discuss how the Ratio and Root Tests work. In addition, you’ll see a […]

What is a geometric series? A series is the sum of the terms of a sequence. What makes the series geometric is that each term is a power of a constant base. For example, Each term in this series is a power of 1/2. Equivalently, each term is half of its predecessor. Whenever there is […]

This article reviews definitions and techniques for finding radius and interval of convergence of power series.

Taylor and Maclaurin series are like polynomials, except that there are infinitely many terms. Read on to find out what you need to know for the AP test!
