Title: 2_7 Some Common Functions
Course: HELM Workbooks 2023-2024 > Section: HELM 2: Basic Functions

This section provides a catalogue of some common functions often used in Science and Engineering. 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.
