Nonlinearity is a term used in statistics to describe a situation where there is not a straight-line or direct relationship between an independent variable and a dependent variable. In a **nonlinear** relationship, the output does not change in direct proportion to a change in any of the inputs.

Correspondingly, what is non linear and linear?

Graphing **Linear** and **Non**-**linear** Functions

The word 'What is nonlinear behavior?

In mathematics and science, a **nonlinear** system is a system in which the change of the output is not proportional to the change of the input. It follows that some aspects of the dynamic **behavior** of a **nonlinear** system can appear to be counterintuitive, unpredictable or even chaotic.

What is a nonlinear function?

As we stated earlier, **nonlinear functions** are **functions** that are not linear **functions**. Therefore, they have the opposite properties of a linear **function**. The graph of a linear **function** is a line. Thus, the graph of a **nonlinear function** is not a line.

Is time non linear?

However, statistical mechanics reveals the 2nd law only to hold approximately for large systems, so by extension the arrow of **time** may only exists approximately for large systems. Which is a **non**-**linear** description of **time**, though it may appear **linear** to observers within those **time** lines.

If the expressions on both sides of the equation are of this form then it is a linear equation. If a **problem** requires **nonlinear** equations to solve then it is a **nonlinear problem**. For example xy=1 is not linear, as is e^x+sin(y)=ln(x+y) and may only arrise in solving **nonlinear problems**.

A **non-linear graph** is a **graph** that is not a straight line. A **non-linear graph** can be described by an equation. In fact any equation, relating the two variables x and y, that cannot be rearranged to: y = mx + c, where m and c are constants, describes a **non- linear graph**.

Using an Equation

Simplify the equation as closely as possible to the form of y = mx + b.
