Analysis

Connect definitions of convergence and continuity with examples and counterexamples and check assumptions.

Meaning

Analysis studies real numbers and limits, continuity, differentiation, and integration using precise definitions and proofs. It examines not just calculations but the conditions permitting approximation or interchange of limits.

Example

To make less than 0.001, it is enough that Specifying a tolerance first and showing that every later term lies within it illustrates the definition of convergence.Observing small values at a few large indices is different from proving convergence. A threshold must be provided for every desired positive tolerance.
