# Mathematics B

Course

Introduction to functions, rates of change, periodic applications, exponential and logarithmic functions, derivatives, integration, and statistical analysis.

Mathematics B:

- Is a pre-requisite for tertiary studies in many fields such as engineering, science and technology, finance;
- helps to make informed decisions in areas such as buying and selling a house, superannuation, interpreting media presentations;
- is important as concepts and application of functions, rates of change, overall change and optimisation are used in the professional setting;
- develops analytical and problem-solving skills useful in everyday life;
- provides the capacity to justify and communicate in a variety of forms; and
- has provided a basis for the development of technology it has substantially influenced the evolution of technology.
