Numerical Methods

Numerical methods are mathematical techniques used to approximate solutions to problems that cannot be solved analytically. These methods are essential for tackling complex equations and differential problems, making them applicable in various fields such as engineering, physics, and computer science. Common numerical methods include root-finding algorithms, interpolation, numerical integration, and the solution of ordinary and partial differential equations. By employing iterative processes and algorithmic approaches, numerical methods enable effective modeling and simulation of real-world phenomena, especially when dealing with large datasets or intricate mathematical models.
