This unit will provide practice and training in the mathematics needed to complete the first year Physics courses and lay the foundations for subsequent years.

  • Topics covered include: The equation of heat conduction, and its solution by half-range Fourier Series.
  • Partial differentiation, the gradient vector and its physical meaning.
  • Contours; tangents and normals to curves.
  • Change of variables and the chain rule.
  • Maxima and minima; stability of equilibrium.
  • Parametric curves, line integrals and work done by a force; conservative fields.
  • Exact differentials.
  • Double integrals, including change of variables and polar coordinates; application to moments of inertia.
  • Green's Theorem relating line integrals to double integrals; application to magnetic field generated by a current.
  • Matrix algebra, matrices as transformations of vectors, rotation and reflection matrices.
  • Determinants. Inverse matrix. Eigenvalues of 2x2 and 3x3 matrices, and application to vibrations.


  • To motivate students to learn mathematics, by showing it in action in physics; to develop students' mathematical skill and introduce the mathematical tools needed for first-year Physics.

Intended learning outcomes

Students will:

  • be able to solve problems using partial differentiation, line integrals, double integrals, Fourier series, matrix algebra, and calculation of eigenvalues and eigenvectors of simple 2x2 and 3x3 matrices.
  • have an appreciation of the physical meaning and application of: the gradient vector, line integrals and conservative fields, Fourier Series, and eigenvalues.

Teaching details

The unit will be taught through a combination of

  • asynchronous online materials, including narrated presentations and worked examples
  • synchronous group problems classes, workshops, tutorials and/or office hours
  • asynchronous directed individual formative exercises and other exercises
  • guided, structured reading

Assessment Details

Weekly problems are both formative (through discussion in tutorials and written feedback) and summative. The final assessment mark for the unit is made up of:

  • Weekly set written problems (10%)
  • weekly set e-assessment problems (10%)
  • final two hour examination (80%).


If this unit has a Resource List, you will normally find a link to it in the Blackboard area for the unit. Sometimes there will be a separate link for each weekly topic.

If you are unable to access a list through Blackboard, you can also find it via the Resource Lists homepage. Search for the list by the unit name or code (e.g. PHYS11400).
