Title: 2.1 Basic Concepts of Functions (copy)
Course: HELM Workbooks 2023-2024 > Section: HELM 2: Basic Functions

In science and engineering there are many quantities that change their value as time changes. For example, the temperature of a furnace may change with time as it is heated. Similarly, there are many quantities that change their value as the location of a point of interest changes. For example, the shear stress in a bridge girder will vary from point to point across the bridge. A quantity whose value can change is known as a variable. We use functions to describe how one variable changes as a consequence of another variable changing. There are many different types of function that are used in different applications. We will be examining some of these later. The purpose of this Quiz is to look at the basic concepts associated with all functions.
