## Module aim (aims)

Module aim (aims)
• to teach students to recognize the type of problems that require numerical techniques for their solution
• to show them some examples of the error propagation that can occur when numerical methods are applied
• to teach the students to approximate the solution to some problems that cannot be solved exactly.
• students are taught to use the numerical analysis methods in MS Excel.

## Pre-requisites in terms of knowledge, skills and social competences (where relevant)

The course is dedicated to students with some knowledge of mathematics and MS Excel.

The course consists of 15h of the lecture and 30 h of the computer classes and 5 ECTS points are given for enrolling for both components of the course (a lecture and classes).
