MATH1052 Differential Equations

Module Overview

The module begins by revising and extending methods of integration from A-level. The module then goes on to look at the role of differential equations in modelling real problems. It then introduces the basic methods used for solving ordinary differential equations (ODEs) and showing how ODEs can be used to model a wide variety of real situations. Techniques for solving various classes of first order differential equations are considered and a number of practical applications will be investigated including applications to finance, biological systems and dynamics. Linear second order ODEs will then be studied and applications to oscillatory motion considered. It is important to note that many differential equations cannot be solved using analytical methods so attention will also be paid to the qualitative behaviour of solutions to ODEs by looking at the phase plane
