What you will study

There are twelve study units in this module.

In the first unit, you’ll revise and consolidate the mathematics taught in Essential mathematics 1 (MST124).

In the remaining study units you’ll cover the following topics.

  • Number theory: you’ll learn about divisibility properties of the integers. These have many practical applications, such as in cryptography.
  • Conics: these are the curves obtained by slicing a cone along a plane. Their applications include modelling the motion of planets and other heavenly bodies.
  • Geometric transformations: these include reflections, rotations and translations, and other similar ways of transforming geometric figures. You’ll use an algebraic approach, involving matrices and vectors.
  • Mathematical language and proof: you’ll look at how mathematical results can be stated clearly, and how they can be proved to be true.
  • Further calculus: you’ll extend your knowledge and skills in calculus.
  • Differential equations: these are equations that involve an unknown function and one or more of its derivatives. They are used extensively in applied mathematics to model a range of situations involving quantities that change.
  • Mechanics: you’ll analyse forces that act on stationary objects, and the motion of moving objects.
  • Eigenvalues and eigenvectors: these are numbers and vectors associated with matrices, which arise in a range of situations in both pure and applied mathematics.
  • Combinatorics: you’ll learn how to solve problems involving the positive integers, such as how many different ways there are to choose objects from a set. You’ll also study some interesting sequences of numbers, such as the Fibonacci sequence.

With a choice of three options of typesetting software, you’ll learn how to typeset mathematics.

You’ll work mainly from the module books, which are available in electronic formats as well as in print. You can view some of the worked examples in the books in an alternative video format, in which tutors work through and discuss the examples. You’ll use specially-designed software applications to help you understand the concepts taught, and the same mathematics computer package as used in Essential mathematics 1 (MST124). There are many online interactive practice questions to help you consolidate your learning.

The module includes a large amount of online study material, and requires you to use mathematical software frequently, so you’ll need regular access to a suitable personal computer.

This module builds on many of the mathematical topics covered in Essential mathematics 1 (MST124). If you have plenty of study time (at least 20 hours per week), a high level of fluency with algebraic manipulation, and a good knowledge of basic topics such as linear and quadratic graphs, linear and quadratic equations, trigonometry, indices and logarithms, it may be possible to study the two modules together. We provide a study schedule to ensure that you study each topic in this module only after you have studied the necessary preliminary topics in Essential mathematics 1 (MST124). Further information on this option is available on our MathsChoices website. If you think this option may suitable for you, please contact us to speak to our Mathematics and Statistics Student Support Team for advice before you register. 

If you are considering progressing to Pure mathematics (M208) or Mathematical methods, models or modelling (MST210), normally you should have completed this module. You are more likely to complete these modules successfully if you have acquired your prerequisite knowledge through passing this OU level 1 module.

Teaching and assessment

Support from your tutor

You will have a tutor who will help you with the study material and mark and comment on your written work, and whom you can ask for advice and guidance. If you are new to the OU, you will find that your tutor is particularly concerned to help you with your study methods. We may also be able to offer group tutorials (online or face-to-face), that you are encouraged, but not obliged, to attend. The locations of face-to-face tutorials will depend on the distribution of students taking the module.

Contact us if you want to know more about study with The Open University before you register.

    Entry requirements

    You must have passed (or be studying) Essential mathematics 1 (MST124) or, if you're studying engineering, Engineering: maths. modelling, applications (T194).

    Essential mathematics 1 (MST124) underpins Essential mathematics 2 (MST125): providing you with a good knowledge of the algebra, functions, trigonometry, vectors, matrices and calculus (differentiation and integration).

    If you already have a strong mathematical background (e.g. an A-Level in mathematics), you may be allowed to study Essential mathematics 2 (MST125) without having first studied Essential mathematics 1talk to an adviser.

    Our self-assessed quiz can help you determine if you have the appropriate level of mathematical knowledge.

    Preparatory work

    In Unit 1 of Essential mathematics 2, you’ll consolidate the mathematical knowledge and skills taught in Essential mathematics 1.

    It’s a good idea to start working through Unit 1 well before the module starts. This will also help you confirm if Essential mathematics 2 is suitable: if you find a lot of the material is unfamiliar, consider taking Essential mathematics 1 first.

    You’ll find more preparation advice at the end of the self-assessed quiz.

    Ways to pay for this module

    Open University Student Budget Account

    The Open University Student Budget Accounts Ltd (OUSBA) offers a convenient 'pay as you go' option to pay your OU fees, which is a secure, quick and easy way to pay. Please note that The Open University works exclusively with OUSBA and is not able to offer you credit facilities from any other provider. All credit is subject to status and proof that you can afford the repayments.

    You pay the OU through OUSBA in one of the following ways:

    • Register now, pay later – OUSBA pays your module fee direct to the OU. You then repay OUSBA interest-free and in full just before your module starts. 0% APR representative. This option could give you the extra time you may need to secure the funding to repay OUSBA.
    • Pay by instalments – OUSBA calculates your monthly fee and number of instalments based on the cost of the module you are studying. APR 5.1% representative.

    Joint loan applications

    If you feel you would be unable to obtain an OUSBA loan on your own due to credit history or affordability issues, OUSBA offers the option to apply for a joint loan application with a third party. For example, your husband, wife, partner, parent, sibling or friend. In such cases, OUSBA will be required to carry out additional affordability checks separately and/or collectively for both joint applicants who will be jointly and severally liable for loan repayments.

    As additional affordability checks are required when processing joint loan applications, unfortunately, an instant decision cannot be given. On average the processing time for a joint loan application is five working days from receipt of the required documentation.
