## Unit Description and General Aims

This unit introduces the student to core mathematical concepts, processes and techniques necessary to support subsequent studies in Engineering. These concepts include, but are not limited to, the properties and engineering applications of linear, quadratic, logarithmic and exponential functions. The unit commences with fundamental concepts of trigonometry, vectors and complex numbers, and goes on to cover basic differential and integral calculus. It then moves to varied subjects including sequences, series, sets, logarithms and exponentials. It rounds off with using matrices to solve equations, followed by an introduction of probability. The topics in this unit are structured in such a manner that the student will be able to solve problems related to engineering applications by using these mathematical techniques.
