Lectures, Numerical calculation practice and computer practice. Consultations. Lectures are conducted combining theoretical part of the subject matter with characteristic examples which facilitate understanding. During practice classes, which accompany the lectures, some characteristic problem tasks are done and the presented material is discussed in more detail. In addition to the lecture and practice classes there are regular consultations. Parts of the course which form a logical unit can be taken in the form of 3 partial exams during the term based on the modules (module one: Laplace transform-part one, extreme values of functions of several variables; Fourier series and integrals, power series solution of differential equations ; module two: triple and surface integrals, field theory ; module three: numerical analysis, Fourier and Laplace transform).
