# MATH2015 Mathematical Methods for Scientists

## Module Overview

This is an optional module for second-year students in physical sciences. The module introduces a number of more advanced methods for solving linear matrix equations and ordinary differential equations, as well as introducing Fourier series, and partial differential equations.

### Aims and Objectives

#### Learning Outcomes

##### Learning Outcomes

Having successfully completed this module you will be able to:

• Perform matrix mathematics techniques, including computing inverses, determinants, eigenvalues and eigenvectors and solving systems of linear equations
• Compute the Fourier series expansion of a given periodic function or its periodic extension
• Solve a range of first and second order ordinary differential equations, including initial and boundary value problems, recognising separable and exact equations, using integrating factors and methods of reduction of order and variation of parameters
• Solve a range of first and second order partial differential equations with boundary conditions using methods of characteristic curves and separation of variables

### Syllabus
