Mathematical Analysis III

Recommended Prerequisites

Mathematical Analysis I and II and Linear Algebra and Analytic Geometry.

Teaching Methods

The teaching in this course will assume two formats: theoretical and example classes. During a theoretical class teaching will be mostly expository. During an example class teaching will consist of problem solving by the students under the guidance of the lecturer. A strong interaction between notions and their practical application is emphasized. In this task, the visualization and the analysis of concrete examples takes on a central role and prepares the way for the abstract definitions. Tutorial support will be available to students to help them on the tasks assigned by the lecturers. 

Learning Outcomes

The student who successfully completes this course will be able to:

i)  classify the singularities of a quotient of analytic functions;

ii) compute the Laurent series of an analytic function on an annulus;

iii) compute the residue of an analytic function on an annulus;

iv) compute the integral of a function along a closed path using the Residue Theorem;

v) compute the Z-transform of a rational function using the method of decomposition into partial fractions;

vi) use the Z-transform to solve difference equations;

vii) compute the Fourier transform and its inverse;

viii) compute the Laplace transform and its inverse;

ix) solve a differential equation using the Laplace transform.
