The taught part of course is delivered to the students by means of lectures, conducted with the help of computer presentations. Lecture notes and presentations are available through the web for students to use in combination with the textbooks. The structure of the course teaching is based on lectures (3 hours per week) in a classroom.  

During the lectures several related exercises are solved on the board with participation of the students. Several problems are left unfinished for the students to complete at home. Other problems are used as assignments. Topic notes are compiled by students, during the lecture which serve to cover the main issues under consideration. Students are also urged to use the textbook assigned to the course. Related homework problems are also assigned from the textbook as a turn in assignment or for homework practice. Also, students are advised to use the reference books for further reading and practice in solving related exercises.
