# INTRODUCTION TO COMPLEX ANALYSIS - 2018/9

Module code: MAT2052

Module Overview

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate:

an understanding of and the ability to interpret and manipulate mathematical statements;

subject knowledge through the recall of key definitions, theorems and their proofs;

analytical ability through the solution of unseen problems in the in-semester test and examination.

The summative assessment for this module consists of:

one two hour examination at the end of Semester 2 – worth 80% of the module mark;

one in-semester test – worth 20% of the module mark.

The formative assessment and feedback for this module includes:

written feedback on two marked pieces of unassessed coursework;

verbal feedback at weekly tutorial sessions.

Module aims

- The aim of this module is to introduce students to the theory of complex functions of a complex variable -- including key concepts such as complex differentiation, integration along contours on the complex plane, series expansions of complex functions, and the calculus of residues. At the end of the module, students should have gained a thorough understanding of the theory of complex functions and should be able to apply this knowledge in a variety of contexts.

Methods of Teaching / Learning

The learning and teaching strategy is designed to introduce students to the theory of complex functions of a complex variable, and its applications.

The learning and teaching methods include:

3 hours of lectures per week x 11 weeks – material supplementing the module notes will be presented on blackboards/whiteboards in these lectures, with Q & A opportunities for students.

1 hour of tutorials per week x 11 weeks – students will work on exercises in this interactive tutorial session, with Q & A opportunities and partial solutions presented on blackboards/whiteboards.

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
