This module introduces you to vector calculus and its applications, especially fluid dynamics but also electromagnetism. It consists of two parts, which are closely linked. In the first part of the module, you will learn about the mathematical theory and techniques of vector calculus. You will develop your competence in using vector calculus in both differential and integral forms. The second part of the module gives an introduction to fluid dynamics and electromagnetism as two applications of vector calculus. It lays down some basic principles using a number of simplifying assumptions. Engaging applets, video examples and experiments are used throughout to illustrate the theory.
This module is a prerequisite for several specialist modules in the third year and fourth year, including MTH3007 Fluid Dynamics (which develops theory for flow with viscosity), MTH3008 Partial Differential Equations, MTH3001 Theory of Weather and Climate, MTHM031 Magnetic Fields and Fluid Flows and MTHM045 Space Weather and Plasmas.
Prerequisite modules: MTH1002, NSC1002 or equivalent
This introductory vector calculus course aims to increase your understanding of fluid dynamics and electromagnetism. It examines how one can use vector formalism and calculus together to describe and solve many problems in two and three dimensions. For example, the rules that govern the flow of fluids can be described using vector calculus, with resulting laws of motion described by partial differential equations rather than ordinary differential equations.
