Below is a comprehensive study guide covering “everything” you need for the AP Calculus AB exam. This guide is organized into key topics, complete with explanations, formulas, sample problems, and study tips. You can use it as a roadmap for your review sessions and practice. ⸻ 1. Limits and Continuity Key Concepts • Definition of a Limit: Understand the formal (ε–δ) definition as well as the intuitive notion of a limit. • One-Sided Limits: Limits as x approaches from the left or right. • Infinite Limits and Limits at Infinity: How functions behave as x goes to infinity or negative infinity, or when the function grows without bound. • Continuity: A function f(x) is continuous at a point if \lim_{x \to c} f(x) = f(c) and on an interval if it’s continuous for every point in that interval. • Intermediate Value Theorem: If f is continuous on [a, b], then for any L between f(a) and f(b), there exists c in (a, b) with f(c) = L. Formulas and Strategies • Evaluating Limits: • Direct Substitution: When possible, plug the value into the function. • Factoring or Rationalizing: For limits that result in indeterminate forms like \frac{0}{0}. • L’Hôpital’s Rule: If \frac{f(x)}{g(x)} ...
