Aims

The absolvent of the subject is able:

- to compute the partial derivatives of the functions of more variables and use the formulas for the gradient and the tangential plane;

- to distinguish between the separable and linear differential equations and also to solve them;

- to solve linear differential equations of higher order with a special right hand side;

- to figure out from the Cauchy Riemann conditions, if the complex function is holomorfic or not, and to derive the holomorfic funcions;

- to compute, using the definition, the integral from the complex function through a curve, to apply the Cauchy theorem for the integral of the holomorfic funcion;

- to establish the poles and to calculate a residue at asimple and at a pole of higher order, to apply the residue theorem for the integral of the meromorfic funcion;

- to solve differential equations by the Laplace transform;

- to find the real Fourier series of an odd, even and a general function, expand a function to sine or cosine series;

- to solve difference equations by the Z- transform.
