Students learn basic numerical methods for eigenvalue computation, polynomial approximation and interpolation, numerical quadrature, and methods for the ordinary differential equations. The acquired knowledge is consolidated by exercises and homework assignements.

Knowledge and understanding: Understanding of basic numerical methods for eigenvalue computation, interpolation, quadrature, and methods for the ordinary differential equations. Knowledge of computer programming and Matlab or other similar software for solving such problems.

Application: Economical and accurate numerical solution of various mathematical problems. In addition to mathematics, numerical methods are used in many other fields when the problem can be described by a mathematical model and a result in a numerical form is required. Many problems can not be solved analytically but only numerically. Also, in some cases, the numerical solution is much more economical than the analytical one.

Reflection: Understanding of the theory from the applications.

Transferable skills: The ability to select an appropriate method, solve a problem, and analize the obtained results. The ability to solve mathematical problems using a computer. Understanding the differences between the exact and the numerical computation. The subject enriches constructively the knowledge of algebra and analysis.
