### MATH3081: APPROXIMATION THEORY & SOLUTIONS OF ODEs III

Type | Open | Level | 3 | Credits | 20 | Availability | Available in 2010/11 and alternate years thereafter | Module Cap | None. | Location | Durham |
---|

#### Prerequisites

- (Numerical Analysis II (MATH2051) AND one extra 20 credit Level 2 mathematics module) OR (Numerical Analysis II (MATH2051) AND Core Mathematics B1 (if taken in Year 2)).

#### Corequisites

- One 20 credit Level 3 mathematics module.

#### Excluded Combination of Modules

- Approximation Theory & Solutions to ODEs IV (MATH4221)

#### Aims

- To build on the foundations laid in the level II Numerical Analysis module and to enable students to gain a deeper knowledge and understanding of two particular areas of numerical analysis.

#### Content

- Approximation theory: Piecewise polynomial approximation and spline functions.
- Approximation by rational functions.
- Trigonometric polynomials and fast Fourier transforms.
- Numerical solution of ordinary differential equations: Introduction to numerical methods for initial-value problems.
- Local and global truncation errors, convergence.
- One-step methods, with emphasis on explicit Runge-Kutta methods.
- Practical algorithms.
- Linear multistep methods.
- Predictor - corrector methods.
- Shooting methods.
- Specialist software will be used for computational work throughout the module.

#### Learning Outcomes

Subject-specific Knowledge:

- By the end of the module students will: be able to solve novel and/or complex problems in Approximation Theory and Solution of Ordinary Differential Equations.
- have a systematic and coherent understanding of theoretical mathematics in the field of Approximation Theory and Solution of Ordinary Differential Equations.
- have acquired coherent body of knowledge of these subjects demonstrated through one or more of the following topic areas: Consistency, convergence and linear stability of numerical methods.
- One-step methods, particularly Runge-Kutta methods.
- Linear multi-step methods.
- Approximation theory.
- Piecewise polynomial approximation and spline functions.
- Approximation by rational functions.
- Trigonometric polynomials and fast Fourier transforms.

Subject-specific Skills:

- In addition students will have specialised mathematical skills in the following areas which can be used with minimal guidance: Modelling, Computation.

Key Skills:

#### Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

- Lectures demonstrate what is required to be learned and the application of the theory to practical examples.
- Assignments for self-study develop problem-solving skills and enable students to test and develop their knowledge and understanding.
- Formatively assessed assignments provide practice in the application of logic and high level of rigour as well as feedback for the students and the lecturer on students' progress.
- The end-of-year examination assesses the knowledge acquired and the ability to solve predictable and unpredictable problems.
