Rules for evaluation and completion of the course
Course-unit credit is awarded on the following conditions: Active participation in seminars fulfilment of all conditions of the running control of knowledge (this concerns also the seminars in computer lab). At least half of all possible points in each of the two tests should be obtained.
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 has written and oral part. The written exam consists in particular of the examples on the following topics:
Solving first order ODEs, solving higher order linear ODEs, solving system of first order linear ODEs, Fourier series, solving ODEs via the infinite series and the Laplace transform method, boundary value problems, basics of PDEs theory,
number and function series, application of convergence tests, the expansion of a function into Taylor series and manipulations with this expansion.
Some theoretical questions concerning basic concepts can be included in the written part as well.
The final grade reflects the result of the written part of the exam (maximum 80 points) and the result of the oral part (maximum 20 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).
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.
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 plays an important role in physics and technical branches. Moreover, it is shown that the infinite series theory is a necessary tool for solving various problems.
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 problems of the convergence of infinite series as well as expansions of functions into Taylor and Fourier series.
