Numerical Analysis is a branch of mathematics that focuses on developing and analyzing methods for solving mathematical problems using numerical approximations. It is essential for tackling complex equations that cannot be solved analytically. Techniques in Numerical Analysis include methods for finding roots of equations, numerical integration, and solving differential equations, which are crucial in fields like engineering, physics, and computer science. The goal of Numerical Analysis is to provide accurate and efficient solutions while minimizing errors. By using algorithms and computational techniques, it allows scientists and engineers to simulate real-world phenomena, optimize processes, and make predictions. This makes Numerical Analysis a vital tool in both academic research and practical applications.
