Numerical methods is a branch of mathematics that focuses on developing algorithms and computational techniques for solving mathematical problems that are difficult or impossible to solve analytically. Numerical methods involve approximating solutions to complex mathematical equations or systems using numerical techniques, such as interpolation, integration, differentiation, optimization, and solving linear or nonlinear equations. These techniques are used in various fields, including engineering, physics, computer science, economics, and many others, to model and analyze complex systems, perform simulations, and make predictions. Numerical methods play a crucial role in modern scientific research and are essential for solving real-world problems that cannot be solved using traditional mathematical methods.
