Numerical analysis - Test
- 1. Numerical analysis is a branch of mathematics that deals with the development and implementation of algorithms for solving problems involving continuous quantities. It encompasses a wide range of techniques for approximating solutions to mathematical problems that are difficult or impossible to solve exactly. These techniques often involve computational methods such as interpolation, numerical integration, and solving differential equations numerically. Numerical analysis plays a crucial role in many scientific and engineering disciplines, providing tools for simulating and optimizing complex systems, analyzing experimental data, and making predictions based on mathematical models.
