Real analysis is a branch of mathematics that deals with the rigorous study of real numbers and real-valued functions, focusing on concepts such as limits, continuity, and convergence. It provides the foundational framework for calculus and is essential for understanding the behavior of functions and sequences in a real-number context.

Limits are fundamental to calculus, providing a way to rigorously define the behavior of functions as inputs approach a particular value or infinity. They are essential for understanding continuity, derivatives, and integrals, forming the basis for analyzing and solving problems involving change and motion.

limits

Continuity in mathematics refers to a function that does not have any abrupt changes in value, meaning it can be drawn without lifting the pencil from the paper. It is a fundamental concept in calculus and analysis, underpinning the behavior of functions and their limits, and is essential for understanding differentiability and integrability.

continuity

Convergence refers to the process where different elements come together to form a unified whole, often leading to a stable state or solution. It is a fundamental concept in various fields, such as mathematics, technology, and economics, where it indicates the tendency of systems, sequences, or technologies to evolve towards a common point or state.
