Learn how to test for the convergence, divergence, or absolute convergence of an infinite series using various criteria and examples. Find out how to apply the limit, ratio, root, integral, p-series, direct comparison, limit comparison, Cauchy condensation, Abel's, alternating series, Dirichlet's, Cauchy's, Stolz–Cesàro, Weierstrass M-test, and other tests.
The two non-repeating lines can be used to verify correct wall-eyed viewing. When the autostereogram is correctly interpreted by the brain using wall-eyed viewing, and one stares at the dolphin in the middle of the visual field, the brain should see two sets of flickering lines, as a result of binocular rivalry.

Dirichlet's test is a method of testing for the convergence of a series, named after Peter Gustav Lejeune Dirichlet. It states that if is a sequence of real numbers and a sequence of complex numbers satisfying is monotonic for every positive integer N, then the series converges.
Learn how to test infinite series for convergence using Cauchy's criterion, which relies on bounding sums of terms. Find the statement, explanation, proof and generalization of this method for complete metric spaces.
The ratio test is a criterion for the convergence of a series where each term is a nonzero real or complex number. It compares the ratio of consecutive terms and their limits, and may be extended to handle cases where the limit is 1 or fails to exist.
A method to test the convergence or divergence of an infinite series or an improper integral by comparing it to a known one. The test is based on the idea that if a series or an integral is dominated by another one, then it has the same behavior.
A geometric series is a series in which the ratio of successive adjacent terms is constant. Learn how to write, evaluate and prove the sum of a geometric series using the formula S = a / (1 - r), where a is the coefficient and r is the common ratio.
Real analysis is the branch of mathematics that studies the behavior of real numbers, sequences and functions. It relies on the properties of the real number system, such as completeness, order and topology, and covers topics such as limits, continuity, differentiability and integrability.
