MATH1571 Single Mathematics B

Please note: This module is not available to Mathematics students.

This module follows on from A-level mathematics, although many topics will be covered afresh. There are three lectures and one tutorial per week. Problems are set to be handed in each week and there is a compulsory examination (Collections) in January. These are all integral parts of the module.

In the first term we will discuss vector algebra and some applications to mechanics and geometry, ordinary differential equations - their classification and solutions, and Fourier analysis - the representation of functions as linear superpositions of sines and cosines.

In the second and third terms we cover functions of several variables, partial differential equations, and probability. The ideas of differentiation and integration extended to functions of two or more variables give rise to partial derivatives and multiple integrals. A partial differential equation expresses a relationship involving a function of two or more variables and some of its partial derivatives. Wave motion is one of the many phenomena described by partial differential equations; an example is vibration of a stretched string, such as a guitar string. The final part of the module provides an introduction to probability.
