A concise overview of limits in calculus, focusing on how to compute one-sided and two-sided limits. It outlines three cases for non-piecewise functions: direct substitution, simplification by factoring or multiplying by the conjugate, and identifying vertical asymptotes using sign charts. The document also addresses how to work with piecewise functions, providing examples for each case. This guide is useful for students learning the fundamentals of calculus and limit evaluation, offering clear steps and examples to aid understanding. It covers essential techniques for evaluating limits, including direct substitution, factoring, and conjugate multiplication. The document also explains how to handle limits involving vertical asymptotes and piecewise functions, providing a comprehensive overview of limit evaluation methods.
