Unit in brief
Learners use differential (rates of change) and integral (summing) calculus to solve engineering
problems and develop a mathematical model of a local and relevant system.
Unit introduction
Many of the products, components and systems that we use have been subject to a rigorous design
process that will have involved the use of calculations including mathematical calculus. During the
design stage, it is important to be able to predict how a product will perform in service, for example
the handling characteristics of a car or the power output from an electrical power supply. Also,
investing time and resources in setting up manufacturing machinery and supply chains is very
expensive – working with formulae and numbers on paper or using a computer involves a lot less
cost and allows engineers to determine optimal (or near-optimal) solutions.
In this unit, you will investigate how to apply differential and integral calculus methods to solve
engineering problems. You will learn about the rules and procedures of calculus mathematics to
obtain solutions to a variety of engineering problems. You will solve a complex problem from your
specialist area of study and perhaps from a local organisation by breaking it down into a series
of linked manageable steps. Each step will be solved using calculus methods learned through
investigation and practice. These mathematical skills are transferable and will be used to support
your study of other topics in the BTEC Nationals engineering programme, for example in mechanical
principles and electrical systems.
As an engineer you need to understand and develop the skills required to solve problems using
calculus and other mathematical procedures. This unit will prepare you well for progressing to
higher education to study for an engineering degree or a Higher National Diploma (HND). It will
also help prepare you for an apprenticeship or for employment in a range of engineering disciplines
as a technician, and will help you work with professional engineers as part of a team working on
cutting-edge products and systems.
Learning aims
