Type of module:

Summary module description:

In this module, we consider the topics related to ODEs including solving first-order, higher- order differential equations and systems of differential equations introduce some fundamental theory of ODEs including existence and uniqueness of solutions and stability.  Then we consider more advanced topics such as ODEs with non-constant coefficients, integral and series solutions, Fourier series and the theory of boundary value problems.

 

Aims:

To introduce and develop the study of ordinary differential equations

Assessable learning outcomes:

By the end of this module students are expected to be able to:

• Solve a range of ordinary differential equations including first-order and high-order ordinary differential equations, and systems of first-order linear equations;


• Construct and use Green's function to solve appropriate ODEs problems;


• Use series solution techniques for ODEs;


• Use integral transform techniques to solve IVPs for ODEs;


• Derive the Fourier series of a function;


• Use eigenfunction expansions to solve appropriate BVPs for ODEs

Additional outcomes:

By the end of the module, the student will also achieve an improved understanding of the issues of existence and uniqueness of solutions and stability of solutions.

Penalties for late submission:

The Support Centres will apply the following penalties for work submitted late:

• where the piece of work is submitted after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for that piece of work will be deducted from the mark for each working day (or part thereof) following the deadline up to a total of five working days;
• where the piece of work is submitted more than five working days after the original deadline (or any formally agreed extension to the deadline): a mark of zero will be recorded.

The University policy statement on penalties for late submission can be found at: https://www.reading.ac.uk/cqsd/-/media/project/functions/cqsd/documents/cqsd-old-site-documents/penaltiesforlatesubmission.pdf
You are strongly advised to ensure that coursework is submitted by the relevant deadline. You should note that it is advisable to submit work in an unfinished state rather than to fail to submit any work.
