The behavior of a system of indepen

The behavior of a system of independent and dependent variables can be plotted and find a mathematical expression that defines the relationship between the variables. When an independent variable is associated with a dependent and the mapping of their relationship is plotted in a rectangular coordinate system, the graph may be a curve or may have repetitive segments and thus is a waveform. The mathematical form of the relationship between variables is the function that describes the curve or waveform.
