(nonâ³linâ²Ä-Är) Not linear; not obeying a linear relationship. In mathematics, a linear equation may be given in the form y = mx + b, where x is the independent variable, and y is the dependent variable. A nonlinear relationship cannot be represented by such an equation.
In mathematics and physical sciences, a nonlinear system is a system in which the change of the output is not proportional to the change of the input.[1] Nonlinear problems are of interest to engineers, physicists[2] and mathematicians and many other scientists because most systems are inherently nonlinear in nature[citation needed].
