Subject specific learning outcomes and competences

At the end of the course students should be able to know the basic concepts and corresponding context, as well as:

- be able to find and draw the domain of the function of two variables;

- compute partial derivatives of arbitrary order for any (even implicitly) function of several variables;

- find the tangent plane to the surface specified by the function of two variables;

- solve separated and linear first order differential equations;

- solve the n-th order differential equation with constant coefficients including the special right-hand side;

- decompose a complex function into a real and imaginary component and determine the functional values of complex functions;

- find the second component of a complex holomorphic function and determine this function in a complex variable including its derivative;

- calculate the integral of a complex function across a curve by parameterizing the curve, Cauchy theorem or Cauchy formula;

- be able to find singular points of complex functions and calculate their residues;

- calculate the integral of a complex function by means of a residual theorem;

- solve by the Laplace transform the n-th order differential equation with constant coefficients;

- find the Fourier series of the periodic function;

- solve by means of Z-transformation n-th order differential equation with constant coefficients;

Learning objectives

The aim of the course is to acquaint students with basic differential calculus of functions of several variables and with general methods of solving ordinary differential equations. Another point is to teach students how to use mathematical transformations (Laplace, Fourier and Z-transformation) and thus give them a guide to alternative solutions of differential and difference equations that are widely used directly in technical fields. To learning an elements of complex analyzes (especially basic methods of integration in a complex field) offers a good tool for solving specific problems in electrical engineering.

Prerequisite knowledge and skills

The knowledge on the secondary school level and the course of Mathematics 1 is required. In order to master the subject matter it is necessary to be able to determine the definition fields of common functions of one variable, understand the concept of limits of one variable function, numerical sequence and its limits. Further it is necessary to know the rules for derivation of real functions of one variable, knowledge of basic methods and methods of integration (decomposition into partial fractions, integration by parts, substitution method) for indefinite and definite integral and to be able to apply them to problems in the scope of Mathematics 1. Knowledge of infinite number series and basic criteria of their convergence as well as power series and search for fields of their convergence are also required.

Syllabus of lectures

Completely identical to the curriculum (see above).

Syllabus of numerical exercises

Copies the outline of fundamentals seminar (numerical exercises).

Syllabus - others, projects and individual work of students

Progress assessment

Maximum 30 points per semester for three written tests. The criterium of course-unit credit is awarded on condition of having at least 10 points in sum from these three written tests.

The condition for passing the exam is to obtain at least 50 points out of a total of 100 possible (30 can be obtained for work in the semester, 70 can be obtained at the final written exam).

Teaching methods and criteria

Teaching methods include lectures, fundamentals seminar (numerical exercises) and computer-assisted exercise.

Controlled instruction

Fundamentals seminar (i.e., numerical exercises) and computer-assisted exercise are required. Any absence must be duly apologized and the studied subject must be completed. During the semester three written tests with a total of 30 points are written. The criterium of course-unit credit is awarded on condition of having together at least 10 points from three written tests.
