This unit is made up of topics that relate to applied linear algebra, the solution of ordinary differential equations and techniques of integration. You will study the properties of vectors and matrices and linear systems of equations including matrix multiplication, inverses, determinants and eigen values and vectors of square matrices. You will explore the application of these techniques to coupled systems of ordinary differential equations with examples from mechanics and ecology using software. You will learn about inverse trigonometric functions and hyperbolic functions and their derivatives. You will study techniques of integration and their application in mechanics to finding volumes of regular bodies, centre of mass and moments of inertia. You will see how to solve linear differential equations and consider applications in mechanics and electrical circuits with the aid of software.

At the completion of this unit students will be able to:

1. apply elementary manipulative skills to solve mathematical problems
2. formulate simple applied problems in mathematical language
3. use the principles of differential and integral calculus and linear algebra in the solution of problems selected from engineering situations
4. solve simple applied problems using software such as MATLAB or Excel.

#### Mandatory conditional prerequisites

You must either have successfully completed the following unit(s) before starting this unit, or currently be enrolled in the following unit(s) in a prior study period; or enrol in the following unit(s) to study prior to this unit:

Please note that your enrolment in this unit is conditional on successful completion of these prerequisite unit(s). If you study the prerequisite unit(s) in the study period immediately prior to studying this unit, your result for the prerequisite unit(s) will not be finalised prior to the close of enrolment. In this situation, should you not complete your prerequisite unit(s) successfully you should not continue with your enrolment in this unit. If you are currently enrolled in the prerequisite unit(s) and believe you may not complete these all successfully, it is your responsibility to reschedule your study of this unit to give you time to re-attempt the prerequisite unit(s).

• Additional materials — Students will require Windows 7 or higher. UniSA does not support Windows XP.
• Audio/Visual equipment — Audio headset with microphone are required to access weekly consultation and help desk facilities.
• Other special requirement — MATLAB access and access to scanner. For more information please see the Special Requirements section of the course page.
