Engineering: mathematics, modelling, applications

This module builds on the engineering concepts and basic mathematics in Engineering: origins, methods, context (T192) and Engineering: frameworks, analysis, production (T193). You’ll begin by strengthening and consolidating your skills and knowledge in past topics to ensure you have a solid foundation of numeracy and algebra essential for understanding new concepts. Next, you’ll explore the techniques of trigonometry, calculus, complex numbers and matrices in the context of engineering, such as motion, heat transfer and basic statics and electricity. You'll finish with guided revision and exam technique development.

What you will study

Mathematics is an essential component of engineering and forms the foundation of many engineering analysis techniques and concepts. The material you’ll study builds on your earlier study, as well as introducing several completely new mathematical concepts. All new mathematical methods in algebra, geometry, trigonometry, complex numbers, differential and integral calculus and matrices will be introduced and their application within an engineering context demonstrated.

Part 1: The language of mathematics
You’ll develop and cement your knowledge of the fundamentals of mathematics that have been introduced in Engineering: origins, methods, context (T192) and Engineering: frameworks, analysis, production (T193). In addition to learning mathematical concepts, you’ll learn how to correctly write and present mathematical content as well as how to read and interpret mathematical arguments. You’ll study topics including, but not limited to: numerical notation; algebra; logarithms and exponentials; solving simultaneous equations; function notation; sigma notation; graphs; and number series.

Part 2: Describing motion and structures with trigonometry and coordinate systems
Next you’ll study concepts required to model and describe engineering structures and systems, including various coordinate systems, trigonometry and vectors. You’ll learn: about Cartesian and polar co-ordinate systems, how to apply them to engineering problems, and how to convert from one to the other; how to model shapes and structures using trigonometry, and the use of vectors and trigonometry to model bodies in motion.

Part 3: Modelling temperature and change using calculus
In this part, you’ll re-engage with the basic calculus met in Engineering: frameworks, analysis, production (T193) and develop your understanding to a level appropriate for describing thermal conditions in simple engineering examples; other examples such as motion will be used to enrich the topic. You’ll learn: mathematical methods for relating displacement, velocity and time; for finding minima and maxima; and for describing harmonic motion. You’ll also develop an understanding of the fundamentals and standard methods in differentiation and integration.

Part 4: Quantifying electricity and mechanics with complex numbers, calculus and matrices
Complex numbers, more advanced calculus, and matrices will form the basis of what you’ll learn in this part. You’ll be introduced to the topics and learn how they can be applied to engineering and to the mathematical concepts you studied in earlier parts. You’ll learn: how to apply and represent complex numbers; the application of calculus to determining rates of change, including heat and temperature; the concept of matrix algebra and its application to solving simultaneous equations.

Part 5: Revision and exam preparation
Finally, time is set aside for you to revisit and practice each topic, with a focus on preparing for the exam. You’ll also develop exam and revision techniques.

Teaching and assessment

Support from your tutor

Throughout your module studies, you’ll get help and support from your assigned module tutor. They’ll help you by:

  • Marking your assignments (TMAs) and providing detailed feedback for you to improve.
  • Guiding you to additional learning resources.
  • Providing individual guidance, whether that’s for general study skills or specific module content.
  • Facilitating online discussions between your fellow students, in the dedicated module and tutor group forums.

Module tutors also run online tutorials throughout the module. Where possible, recordings of online tutorials will be made available to students. While these tutorials won’t be compulsory for you to complete the module, you’re strongly encouraged to take part.

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.
