Learning outcomes of the course unit
Students will acquire knowledge of basic types of differential equations. They will be made familiar with differential equations as mathematical models of given problems, with problems of the existence and uniqueness of the solution and with the choice of a suitable solving method. They will master solving of problems of the convergence of infinite series as well as expansions of functions into Taylor and Fourier series.
Prerequisites
Linear algebra, differential and integral calculus of functions in a single and more variables.
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 40 points in both check tests (the first test takes place in 7th week of the semester, the second one in 12th 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 and oral, the written part (90 minutes) consists of 12 test examples.
Topics of the written part: Number, function, power and Fourier series, ODEs and their properties, solving of ODEs via the infinite series method and the Laplace tranform method, orthogonal trajectories, stability, autonomous systems.
The final grade reflects the result of the written part of the exam (maximum 60 points) and the results achieved in seminars (maximum 40 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 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 obligatory and checked. Lessons are planned according to the week schedules. Absence from seminars may be compensated for by the agreement with the teacher.

The course is realized in computer labs. The MAPLE software is utilized to illustrate and complete the following topics: 1. Function series – graphical illustrations of types of the convergence (with a special emphasize on Taylor and Fourier series). 2. ODEs – graphical methods of solving (direction fields), geometrical interpretation of solutions (the phase portrait), the Taylor series method, geometrical applications (orthogonal trajectories and others).
