Course detail
Mathematics II
FSI-2M-A Acad. year: 2021/2022 Summer semester
Differential and integral calculus of functions of several variables including problems of finding maxima and minima and calculating limits, derivatives, differentials, double and triple integrals. Also dealt are the line and surface integrals both in a scalar and a vector field. At seminars, the MAPLE mathematical software is used.

Learning outcomes of the course unit
Students will be made familiar with differential and integral calculus of more variables. They will be able to apply this knowledge in various engineering tasks. After completing the course students will be prepared for further study of physics, mechanics and other technical disciplines.
Prerequisites
Linear algebra, differential and integral calculus of functions of one variable.
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 REQUIREMENTS: The course includes seminars and exercises in the computer lab. There are two written tests within the seminars. Students may achieve max 12 points in each of these two tests, i.e. 24 points altogether. The course-unit credit is conditional on obtaining at least 6 points in each written test. If the minimum number of points is not achieved, students may repeat the test during the first two weeks of the examination period.
FORM OF EXAMINATIONS:
The exam has a written part (at most 75 points) and an oral part (at most 25 points).
WRITTEN PART OF EXAMINATION (at most 75 points)
In a 120-minute written test, students have to solve the following four problems:
Problem 1: In basic properties of functions of several variables: domains, partial derivatives, gradient (at most 10 points)
Problem 2: In differential calculus of functions of several variables (at most 22 points)
Problem 3: In double and triple integral (at most 20 points)
Problem 4: In line and surface integral (at most 23 points)
The above problems can also contain a theoretical question.
ORAL PART OF EXAMINATION (max 25 points)
• Discussion based on the written test: students have to explain how they solved each problem. Should the student fail to explain it sufficiently, the test results will not be accepted and will be classified by 0 points.
• Possible theoretic question.
• Possible simple problem to be solved straight away.
• The results achieved in the written tests in seminars may be taken into account within the oral examination.
FINAL CLASSIFICATION:
0-49 points: F
50-59 points: E
60-69 points: D
70-79 points: C
80-89 points: B
90-100 points: A
Language of instruction

Aims
The course aims to acquaint the students with the basics of differential and integral calculus of functions of several variables. This will enable them to attend engineering courses and deal with engineering problems. Another goal of the course is to develop the students' logical thinking.
Specification of controlled education, way of implementation and compensation for absences
Attendance at lectures is recommended, attendance at seminars is required. The lessons are planned on the basis of a weekly schedule. The way of compensation for an absence is fully at the discretion of the teacher.
