Additional Requirements

MATH36022 pre-requisites


To introduce students to theoretical and practical aspects of best approximation, quadrature, and the numerical solution of ordinary differential equations.


This module introduces numerical methods for approximating functions and data, evaluating integrals and solving ordinary differential equations. It continues the introduction to numerical analysis begun in MATH20602. It provides theoretical analysis of the problems along with algorithms for their solution. Insight into the algorithms will be given through MATLAB illustrations, but the course does not require any programming.

Learning outcomes

On completion of the module, students will be familiar with:

  • characterise the best approximation of a function using different norms,
  • compute Padé approximations and evaluate their quality,
  • derive quadrature rules and their error bounds,
  • apply the Trapezium rule, Gauss quadrature and adaptive quadrature to compute integrals,
  • describe the Romberg scheme in the context of extrapolation,
  • analyse and apply one-step, multi-step, and the Euler method for solving ordinary differential equations (ODE),
  • solve ODE numerically using Runge-Kutta, Trapezium and higher-order methods,
  • quantify the error and convergence of numerical solvers for ODE,
  • recognize some of the difficulties that can occur in the numerical solution of problems arising in science and engineering.

Feedback methods

Feedback tutorials will provide an opportunity for students' work to be discussed and provide feedback on their understanding.  Coursework or in-class tests (where applicable) also provide an opportunity for students to receive feedback.  Students can also get feedback on their understanding directly from the lecturer, for example during the lecturer's office hour.

Study hours

  • Lectures - 22 hours
  • Tutorials - 11 hours
  • Independent study hours - 67 hours
