 Planned learning activities and teaching methods: The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
 Assesment methods and criteria linked to learning outcomes: Course-unit credit is awarded on the following conditions: Active participation in seminars. Fulfilment of all conditions of the running control of knowledge. At least half of all possible 20 points in both check tests (the first test takes place in 8th week of the semester, the second one in 13th week of the semester). If a student does not fulfil this condition, the teacher can set an alternative one. Examination: The examination tests the knowledge of definitions and theorems (especially the ability of their application to the given problems) and practical skills in solving of examples. The exam is written (possibly followed by an oral part). The written exam consists of the test part (8 examples) and the practical part (4 examples). Topics of the test part: Number and function series, Fourier series, ODEs and their properties, solving of ODEs via the infinite series and the Laplace tranform method, simple physical task, basics of PDEs theory. Topics of practical part: The expansion of a function into Taylor series, solving of first order ODEs, solving of higher order linear ODEs, solving of system of first order linear ODEs. The final grade reflects the result of the written part of the exam (maximum 75 points), the results achieved in seminars (maximum 20 points) and the results achieved in seminars in computer labs (maximum 5 points). Grading scheme is as follows: excellent (90-100 points), very good (80-89 points), good (70-79 points), satisfactory (60-69 points), sufficient (50-59 points), failed (0-49 points).

 Aims: The aim of the course is to explain basic notions and methods of solving ordinary and partial differential equations, and foundations of infinite series theory. The task of the course is to show that knowledge of the theory of differential equations can be utilized especially in physics and technical branches. Moreover, it is shown that foundations of infinite series theory are important tools for solving various problems.
 Specification of controlled education, way of implementation and compensation for absences: Attendance at lectures is recommended, attendance at seminars is checked. Lessons are planned according to the week schedules. Absence from seminars may be compensated for by the agreement with the teacher.
