Throughout the 2020-21 academic year, we will be adapting the way we teach and assess your modules in line with government guidance on social distancing and other protective measures in response to Coronavirus. Teaching will vary between online and on-campus delivery through the year, and you should read guidance from the academic department for details of how this will work for a particular module. You can find out more about the University’s overall response to Coronavirus at:

PX149-24 Mathematics for Physicists

Undergraduate Level 1
Module leader
Neil Wilson
Credit value
Module duration
20 weeks
Study location
University of Warwick main campus, Coventry
Introductory description

All scientists use mathematics to state the basic laws and to analyze quantitatively and rigorously their consequences. The module introduces the concepts and techniques, which will be assumed by future modules. These include: complex numbers, functions of a continuous real variable, integration, functions of more than one variable and multiple integration.

Module aims

To revise relevant parts of the A-level syllabus, to cover the mathematical knowledge to undertake first year physics modules, and to prepare for mathematics and physics modules in subsequent years.

Outline syllabus

This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.

Term 1

Vector algebra, scalar and vector product

Power Series: Convergence, ratio test and interval of convergence, Taylor Series and applications

Functions of two or more variables: Contours and cross-sections; partial differentiation, Taylor series, maxima, minima and saddle points; introduction to partial differential equations; change of co-ordinates ((x,y)-> (r,θ)); the gradient vector of functions of 2 and 3 variables

Term 2

Riemann Integral: Standard Integrals, use of change of variables; multiple Integrals, double integrals and volume under a surface; change of variable and change of order of integration; introduction to line, surface and volume integrals in physics

Fourier series: Conditions for convergence, orthogonality relations, computation of Fourier coefficients, examples. Periodic extensions; symmetric and antisymmetric functions; sine and cosine series; arbitrary periods. Parseval's theorem, Gibbs phenomenon

Linear algebra: Matrices, matrix addition and multiplication. Simultaneous linear equations and their solution by Gaussian elimination, row-reduced echelon form; idea of a linear map and relation to matrices. Determinants: Definition using co-factors and properties; inverse of a square matrix, conditions for its existence, adjugate matrix, relation to solution of simultaneous equations; efficiency of algorithms, LU decomposition; orthogonal, Hermitian and unitary matrices

Eigenvalues and characteristic equation; eigenvectors, their orthogonality for Hermitian matrices; similarity transformations, corresponding invariance of determinant and trace, use to diagonalise matrices

Learning outcomes

By the end of the module, students should be able to:

  • Explain the notion of a complex number and manipulate expressions involving complex numbers
  • Solve some types of first and second order Ordinary Differential Equations.
  • Explain the notion of convergence and obtain the interval of convergence of a series.
  • Work with functions of more than one variable and with partial differentiation.
  • Determine the gradient vector of a function of 2 and 3 variables.
  • Deal with multiple integrals and know how to evaluate the volume of a three dimensional object
  • Describe and evaluate line and surface integrals
  • Discuss Fourier series and compute the Fourier coefficients of a function
  • Work with elements of linear algebra including: matrices, determinants, eigenvalues and eigenvectors and the diagonalisation of matrices.
