### Pre-requisites

 MATH1035 Analysis

This module is approved as an Elective

### Module summary

This module aims to develop the ideas of MATH1035 Analysis and show how they can be extended to the complex valued functions. It will develop students' ability to appreciate the importance of proofs, and to understand and write them.

### Objectives

On completion of this module, students should be able to:

a) apply convergence tests to series of real and complex numbers and evaluate the radius of convergence of power series;
b) use the Cauchy-Riemann equations to decide where a given function is analytic;
c) calculate upper and lower Riemann sums;
d) determine whether improper integrals converge;
e) compute standard contour integrals using the fundamental theorem of the calculus, Cauchy's theorem or Cauchy's integral formula;
f) classify the singularities of analytic functions and to compute, in the case of a pole, its order and residue;
g) evaluate typical definite integrals by using the calculus of residues.

### Syllabus

1. Revision of complex numbers up to the complex exponential function.
2. Sequences of complex numbers. Limits. Convergent sequences are bounded. Cauchy sequences. Completeness of C.

14. Taylor's theorem. Formula for coefficients in complex Taylor series. Differentiable functions are infinitely differentiable.
15. Calculus of residues. Definitions of pole of order m, simple pole, removable singularity, essential singularity, residue.
