Cauchy (Augustin-Louis Cauchy)

Augustin-Louis Cauchy was a 19th-century French mathematician who made foundational contributions to analysis and complex functions. He developed rigorous methods to understand limits, continuity, and convergence, ensuring that mathematical proofs are precise and reliable. Cauchy's work introduced key concepts like the Cauchy integral theorem and Cauchy-Riemann equations, which are essential in modern calculus and complex analysis. His efforts helped transform mathematics into a more rigorous and structured discipline, ensuring that calculations and proofs are trustworthy and consistent.
