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:

- An introduction to Integration in multiple dimensions and their application in Physics, Cartesian coordinate system;
- Numerical methods for evaluation of double integrals with Continuous Integrands using Python;
- A discussion on cylindrical and spherical polar coordinates;
- Integration in multiple dimensions;
- An introduction to vector transformation, vector operators including the gradient, divergence, curl and Laplace operators together with their uses;
- An introduction to vector fields and potential theory including the notion of scalar and vector potentials;
- 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 to the property and uses of orthogonal curvilinear coordinates;
- An introduction to the use and properties of the Kronecker Delta and the Dirac Delta function;
- An introduction to Fourier transforms;
- A discussion on Green's function.
