- Teaching Location: Newcastle City Campus
Semester 2 Credit Value:
To introduce a range of advanced concepts and methods for solving ordinary and partial differential
Many applications of mathematics lead to problems where the unknown is a function, a law
expressing the dependence of a certain variable on others. Fundamental laws of nature often involve
not only functions that characterise a certain phenomenon but also their rates of change in space
and/or time. In such problems, the governing equation contains not only unknown functions but also
their derivatives: these are differential equations.
This course continues the exploration of differential equation that started in Stage 1, with emphasis
on methods to solve them, both exact and approximate. The essential elements in the theory of
ordinary and partial differential equations, and their methods of solution, introduced in this course,
provide the basis for specific studies in other modules. The methods that will be introduced, justified and practiced apply to a wide range of ordinary and partial differential equations. The course will focus on understanding and solving differential equations rather than on extensive physical interpretation (although this aspect certainly will be mentioned).
Outline Of Syllabus
• A review of the fundamental concepts of ordinary and partial differential equations.
• Series solutions.
• Elements of the Sturm-Liouville theory.
• Fourier series and Fourier transforms.
• Wave equation: simple derivation in one spatial dimension, generalisation to three dimensions,
fundamental properties (D’Alembert’s solution, phase speed, plane waves, superposition, standing
and travelling waves), wave packets.
• Second-order partial differential equations. Separation of variables in Cartesian coordinates:
application to the wave, heat, Laplace’s and Poisson’s equations.

Teaching Rationale And Relationship
Lectures are used for the delivery of theory and explanation of methods, illustrated with examples, and for giving general feedback on marked work. Problem Classes are used to help develop the students’ abilities at applying the theory to solving problems. Tutorials are used to identify and resolve specific queries raised by students and to allow students to receive individual feedback on marked work. In addition, office hours (two per week) will provide an opportunity for more direct contact between individual students and the lecturer: a typical student might spend a total of one or two hours over the course of the module, either individually or as part of a group.
The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship
A substantial formal unseen examination is appropriate for the assessment of the material in this module. The coursework assignments will consist of two written assignment of approximately equal weight. The coursework assignments and the (in class, therefore 40 minute) coursework test allow the students to develop their problem solving techniques, to practise the methods learnt in the module, to assess their progress and to receive feedback; these assessments have a secondary formative purpose as well as their primary summative purpose.
