Learning objectives:
In the first part the student will be acquainted with some numerical methods (approximation of functions, solution of nonlinear equations, approximate determination of a derivative and an integral, solution of differential equations) which are suitable for modelling various problems of practice. The other part of the subject yields fundamental knowledge from the probability theory (random event, probability, characteristics of random variables, probability distributions) which is necessary for simulation of random processes.
Description:
Numerical mathematics: Metric spaces, Banach theorem. Solution of nonlinear equations. Approximations of functions, interpolation, least squares method, splines. Numerical derivative and integral. Solution of ordinary differential equations, one-step and multi-step methods. Probability: Random event and operations with events, definition of probability, independent events, total probability. Random variable, characteristics of a random variable. Probability distributions used, law of large numbers, limit theorems. Rudiments of statistical thinking.
Knowledge and skills required for the course:
Secondary school mathematics and some topics from Discrete Mathematics and Mathematical Analysis courses.
Learning outcomes and competences:
Students apply the gained knowledge in technical subjects when solving projects and writing the Bc. thesis. Numerical methods represent the fundamental element of investigation and practice in the present state of research.
