ODEs and Applications

MATH11422 ODEs and Applications 20 Semester 2 Undergraduate Level 1 Marcus Webb Unit coordinator Gareth Wyn Jones Unit coordinator 1 FHEQ level (Framework for Higher Education Qualifications) ' First part HE study/Bachelors ' European Credit Transfer & Accumulation System Rating : 10.0 The unit provides a basic introduction to ordinary differential equations (ODEs) and applications. The course will discuss both methods, including analytical as well graphical and approximate methods associated with general first and second order ODEs. Applications including simple problems drawn from many fields including Newtonian mechanics, population models, economics, biology, will be introduced, and the corresponding equations will be written down and their solutions discussed.

Perform phase plane analysis.</li> <li>Derive equations of motion for a single particle in rectilinear and circular motion. Derive integrals of motion and relate them to conserved quantities.</li> <li>Analyse the damped, driven harmonic oscillator using second order ODEs with constant coefficients.</li> <li>Analyse and interpret population models described by first order systems of ODEs.</li> <li>Apply and interpret the results of a simple numerical method (the Euler method) for approximately solving initial value problems.</li></ul> 0 Other 20% 1 Written exam 80% There is a supervisions each week which provides an opportunity for students; work to be marked and 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.
