BSc Computer Science and Mathematics

The unit provides a basic introduction to ordinary differential equations (ODEs) and some 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.

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.

The main aims are to:

1. Provide a classification of ODEs
2. Provide analytical methods of solving both first and second-order ODEs;
3. Introduce approximate methods (graphical, numerical, approximate) for solving first order and systems of first order equations.
4. Introduce model problems leading to ODEs.

On the successful completion of the course, students will be able to:

• Classify ODEs (in terms of order, linear/nonlinear autonomous/nonautonomous, initial or boundary value problem) and assess the existence and uniqueness of their solutions.
• Select and apply techniques for finding analytical solutions for several classes of first and second order ODEs.&
• Locate equilibrium points for first order systems of ODEs and perform phase plane analysis.&
• Apply and interpret the results of a simple numerical method (the Euler method) for approximately solving initial value problems.

There are supervisions each week for the first half of the semester which provide an opportunity for students; work to be marked and discussed and to 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.

All students should normally be able to complete their programme of study without incurring additional study costs over and above the tuition fee for that programme. Any unavoidable additional compulsory costs totalling more than 1% of the annual home undergraduate fee per annum, regardless of whether the programme in question is undergraduate or postgraduate taught, will be made clear to you at the point of application. Further information can be found in the University's Policy on additional costs incurred by students on undergraduate and postgraduate taught programmes (PDF document, 91KB).

The University of Manchester is committed to attracting and supporting the very best students. We have a focus on nurturing talent and ability and we want to make sure that you have the opportunity to study here, regardless of your financial circumstances.
