ABSTRACT
Numerical analysis, a core area of applied mathematics, plays an essential role in solving real-world problems across multiple disciplines, including engineering, physics, economics, and biology. The interdisciplinary nature of numerical analysis stems from its fundamental objective: to approximate solutions to complex mathematical models when analytical solutions are not feasible. This paper explores the multidisciplinary applications of numerical analysis, reviewing its role in different fields, methodologies employed, and presenting equations used in diverse contexts. The paper concludes with a discussion of results and potential future developments, illustrating how numerical analysis will continue to shape and drive advancements in science and technology.
