Module description

This is an introductory epsilon-delta analysis module. Students will develop their sense of rigour and precision.

Module aims

The aims of this module are:



  • To introduce the idea of epsilon-delta rigorous analysis.

  • To enhance students’ ability at understanding and writing proofs of results in real analysis.

  • To enhance students’ skills at using results of real analysis.

Module learning outcomes

By the end of the module, students will be expected to:



  1. Understand basic proofs and proof techniques in relation to real numbers, suprema and infima, limits (sequences, series and functions), continuity and differentiability.

  2. Be able to give proofs of some simple standard facts in rigorous real analysis.

  3. Be able to use these techniques on appropriate problems, including working out proofs of simple results related to the module.

Module information

Indicative syllabus:


Numbers systems such as the real and rational numbers. Basic properties of real numbers: field structure, order relation, triangle inequality, Archimedes' Axiom. (No formal construction of the real numbers). Suprema and infima. Dedekind's axiom and its use in proving that bounded-above, non-empty sets of reals have suprema.
Sequences and convergence. Sums, differences, scalar multiples, products and quotients of convergent sequences.
Cauchy sequences and the equivalence of the Cauchy property and convergence.
Series. Comparison and ratio tests. Absolute convergence implies convergence.
Power series and the radius of convergence.
Limits of functions, continuous functions of one real variable. Related results such as sums, products, quotients and compositions (chain rule).
Intermediate Value Theorem. Boundedness and attainment of bounds for continuous functions on closed bounded intervals.
Differentiable functions. Examples of differentiable and non-differentiable functions. Differentiable implies continuous.
Theorems related to continuous and differentiable functions, such as Rolle's Theorem and the Mean Value Theorem.

Learning and teaching methods

Teaching in the School will be delivered using a range of face-to-face lectures, classes, and lab sessions as appropriate for each module. Modules may also include online only sessions where it is advantageous, for example for pedagogical reasons, to do so.

Exam format definitions

  • Remote, open book: Your exam will take place remotely via an online learning platform. You may refer to any physical or electronic materials during the exam.
  • In-person, open book: Your exam will take place on campus under invigilation. You may refer to any physical materials such as paper study notes or a textbook during the exam. Electronic devices may not be used in the exam.
  • In-person, open book (restricted): The exam will take place on campus under invigilation. You may refer only to specific physical materials such as a named textbook during the exam. Permitted materials will be specified by your department. Electronic devices may not be used in the exam.
  • In-person, closed book: The exam will take place on campus under invigilation. You may not refer to any physical materials or electronic devices during the exam. There may be times when a paper dictionary, for example, may be permitted in an otherwise closed book exam. Any exceptions will be specified by your department.

Your department will provide further guidance before your exams.

Further information

Disclaimer: The University makes every effort to ensure that this information on its Module Directory is accurate and up-to-date. Exceptionally it can be necessary to make changes, for example to programmes, modules, facilities or fees. Examples of such reasons might include a change of law or regulatory requirements, industrial action, lack of demand, departure of key personnel, change in government policy, or withdrawal/reduction of funding. Changes to modules may for example consist of variations to the content and method of delivery or assessment of modules and other services, to discontinue modules and other services and to merge or combine modules. The University will endeavour to keep such changes to a minimum, and will also keep students informed appropriately by updating our programme specifications and module directory.
