These include polynomials, rational functions, the modulus function and the unit step function. Important properties and definitions are stated. This section can be used as a reference when the need arises. There are, of course, other types of function which arise in engineering applications, such as trigonometric, exponential and logarithm functions.<br><\/p>",
