Real Analysis

This lecture series provides a comprehensive introduction to real analysis, drawing on Terence Tao's Analysis I. Structured to build from foundational concepts to advanced theorems, it begins with the Axioms of Completeness and Least Upper Bound Property, exploring real number structure, sequences (convergence, limits, Cauchy sequences), and key results like Bolzano-Weierstrass. The series transitions to continuity (epsilon-delta definitions, Intermediate/Extreme Value Theorems), uniform continuity, and algebraic properties of continuous functions. Later lectures focus on differentiation (derivatives, Mean Value Theorem) and applications including Inverse Function Theorem and L’Hôpital’s Rule. Emphasizing rigorous proofs and central theorems, the series connects theoretical foundations with analytical tools, offering systematic progression from real numbers to function behavior while highlighting Tao's pedagogical approach.
