1 INTRODUCTION
Dear Student
Welcome to COS1501! This is a semester module presented by the School of Computing. (The
previous module code was COS101S.)
This module is a blended online module as from 2017. This means that you have to work through
the learning units on myUnisa, and follow the instructions when you are guided to work through
the respective study guide units. You will also find the learning units in tutorial letter
MO001/4/2019 under Additional Resources on myUnisa.
This module focuses on discrete mathematics and its application in Computer Science. Concepts
and skills needed for a theoretical understanding of Computer Science are introduced. If you feel
a flash of fear when you hear the word “theoretical”, just remember that theory is much tidier than
practice: one knows precisely what the meaning of the terms is and the problems always have
solutions. Rigorous proofs are expected in this module.
This module does not involve practical work on a computer, but there is a strong emphasis on
practicing the skills acquired by means of doing many exercises and the assignments.
Studying a mathematical module is rather like learning to play a musical instrument – the more
you practice, the better you become! If you put an honest effort into trying to do the self-
assessment exercises and assignments, we believe that by the end of the semester you will be
able to do a lot of things you had never heard of before, and enjoy doing them.
2 PURPOSE OF AND OUTCOMES FOR THE MODULE
2.1 Purpose
On completing this module, you will be able to critically apply the fundamental knowledge and
skills of discrete mathematics. The module forms part of the theoretical foundation of a Computer
Science major. This background is relevant to computing fields such as relational databases, the
development of provably correct programs, and the analysis of algorithms that will contribute to
the development of computing in Southern Africa, Africa, or globally. The module will support
further studies and applications in the computing discipline.
2.2 Outcomes
Specific outcome 1: Manipulate logical arguments, using a variety of mathematical tools.
Specific outcome 2: Construct proofs in a clear and concise way using mathematical reasoning
techniques.
