# Engineering Mathematics KME771

### Introduction

This unit is primarily concerned with extending concepts of single variable calculus into the domain of several variables. It also looks at the construction of periodic functions with Fourier series.

The calculus section of this unit is focussed on dealing with functions of several variables, of which the typical case is z = f(x,y). Functions like this are
important because they describe many of the situations we encounter when applying mathematics to models of the real world. The graph of the
function z = f(x,y) is a surface, so it might be used to describe building structures; aeroplane wings; temperature, stress, and pressure distributions;
and so on. We need to be able to say how rapidly such a surface curves, and that immediately requires us to do calculus on functions of two (or more) variables.

We will also need to consider vectors that are functions of several variables. Some obvious examples are the velocity vector in a moving fluid,
the heat-flow vector in a solid, and the electric and magnetic fields produced by an antenna. This will lead us to consider more advanced concepts
such as circulation, compressibility, divergence, and curl. Understanding this material is fundamental to the study of all areas of Engineering and
(continuum) Applied Mathematics, and it underpins modern continuum mechanics and electromagnetic theory.
Topics will be introduced in the Cartesian (rectangular) coordinate system but we will also investigate functions, regions, vectors, operations, and integration in
cylindrical and spherical coordinates.

The Fourier-Series section of this unit is concerned with how to represent periodic functions. Previously we have looked at power series as an infinite
sum of terms involving increasing powers of a particular variable. A Fourier series is an infinite sum of terms involving sine and cosine functions. This
is an important concept for solving problems in acoustics, signal processing, heat-flow theory, fluid mechanics, vibrations, electromagnetic field theory,
and so on.

##### Note

Please check that your computer meets the minimum System Requirements if you are attending via Distance/Off-Campus.

Units are offered in attending mode unless otherwise indicated (that is attendance is required at the campus identified). A unit identified as offered by distance, that is there is no requirement for attendance, is identified with a nominal enrolment campus. A unit offered to both attending students and by distance from the same campus is identified as having both modes of study.

#### Textbooks

Required Required readings will be listed in the unit outline prior to the start of classes. Students who completed KMA152 and KMA154 should have downloaded a copy of the following text.  Thomas’ Calculus, 14th edition in SI Units (electronic), Hass et al. (Pearson Education, 2020). You will also find a significant amount of material for this unit in books such as:  Calculus, 8th edition Metric Version, J Stewart (Cengage 2016) Advanced Engineering Mathematics, 9th edition, E. Kreyszig (Wiley 2006) Advanced Engineering Mathematics, 3rd edition, D Zill and M Cullen (Jones and Bartlett 2006) Advanced Engineering Mathematics, 8th edition, P O’Neil (Cengage 2018) The Advanced Engineering Mathematics texts are excellent reference books, covering a plethora of applied mathematics topics including linear algebra, vector calculus, differential equations (ordinary and partial), Fourier analysis, complex analysis, numerical analysis, optimisation, and probability and statistics. There are many topics that you will meet in other Engineering units. There is quite a large number of text-books with the same or similar title, and you should be able to find some of these in the library. Booktopia textbook finder
