Applications of linear systems of the form dx/dt = Ax to chemical mixing problems; the idea of compartmental analysis. Engineering applications of second order systems of the form d2 x/dt2+A x=0, e.g. to railway carriages connected by springs. Forced systems of the form d2 x/dt2+A x=f(t); resonance.
The Laplace transform and its properties. The Heaviside and Dirac delta functions and applied problems that give rise to differential equations containing those functions, for example the bending of a supported beam subject to a load at a particular point, and mathematical models of drug therapy.
Calculus of Variations. The Euler-Lagrange equation. Examples to include the brachistochrone, the catenary (hanging cable) and isoperimetric problems. Variational problems with constraints: Lagrange multipliers and endpoint conditions.
Applications of nonlinear equations. Phase plane techniques applied to problems such as the nonlinear pendulum equation and van der Pol's equation. Simple analytical techniques for weakly nonlinear equations.
Methods of Teaching / Learning
The learning and teaching strategy is designed to provide:
A detailed knowledge of analytical techniques relevant to the solution of differential equations arising in applied contexts;
Examples, considered in detail, of the modelling of real life problems which can be described by those differential equations;
Solutions of those example problems and an appreciation of how we can interpret the results.
The learning and teaching methods include:
3 one hour lectures per week for 11 weeks, each session being a blend of traditional lecturing and class discussion.
The assessment strategy is designed to provide students with the opportunity to demonstrate
· Adequate knowledge of analytical techniques for solution of differential equations that arise in applied problems.
· Skills in modelling real-life problems.
· Skills in interpreting the results of the analysis.
Thus, the summative assessment for this module consists of:
· One two-hour examination worth 80%.
· One in-semester test, approximately in week 6, worth 20%.
Formative assessment and feedback
This takes the form of four marked exercise sheets issued at roughly equal intervals throughout the course. Written feedback is provided.
