DEPARTMENT Physics

 
DESCRIPTION This study-unit discusses a number of important mathematical techniques that are used in a number of physics topics. These include multiple integrals, transformation of coordinates in multiple integrals, Green’s theorem, Gauss’ theorem, Stokes’ theorem and orthogonal curvilinear coordinates. The theoretical framework behind this mathematical techniques is discussed in full. However, the emphasis will be on their applications through the use of various examples. These examples will preferentially be chosen from physical applications creating a link between this topic and the other units where the mathematical techniques are used.

Study-unit Aims:

The objective of this study-unit is to teach the candidate a number of mathematical techniques that find application in a number of physics topics. This will be carried out by first outlining the theory behind the mathematical methods. Then the techniques will be applied on a number of different examples. The examples will preferentially be derived from physical applications to create a link between the theory and the practical application. This is meant to teach when and how to use these mathematical techniques. More specifically the study will provide:

- A discussion on cylindrical and spherical polar coordinates;
- An introduction to line integrals, double integrals, triple integrals and multiple integrals;
- An introduction to the use and properties of the Kronecker Delta and the Dirac Delta function;
- An introduction to Fourier transforms;
- A discussion on the use of the Jacobian for the transformation of coordinates in multiple integrals;
- An introduction to vector operators including the gradient, divergence, curl and Laplace operators together with their uses;
- The statement and use of Green’s theorem;
- The statement and use of Gauss’ (Divergence) theorem;
- The statement and use of Stokes’ theorem;
- An introduction potential theory including the notion of scalar and vector potentials;
- An introduction to the property and use of orthogonal curvilinear coordinates;
- A discussion on Green's function;
- A discussion on series and limits.
