This document defines antiderivatives (also called indefinite integrals) and provides examples of finding antiderivatives of various functions. The key points are: - An antiderivative of a function f(x) is any function F(x) whose derivative is f(x). - The general form of an antiderivative is F(x) + c, where c is an arbitrary constant. - Rules are provided for finding antiderivatives of basic functions using integration formulas and techniques like substitution. - Applications of antiderivatives include graphing functions from their derivatives, and solving boundary value problems in fields like physics.
