The Integral Test is a calculus theorem used to determine the convergence of infinite series by comparing them to improper integrals. It requires the function to be continuous, positive, and decreasing on [1, ∞). This test is crucial for series that are difficult to sum, such as ∑(1/n^2), and is complemented by the Comparison Test for assessing convergence.
