# Odd Function

## Topic

Functions and Relations

## Definition

An odd function is a function that satisfies the condition f(−x) = −f(x) for all x in its domain.

## Description

Odd functions are important in mathematics because they exhibit symmetry about the origin. This property is useful in various fields, including physics and engineering, where symmetry simplifies analysis and problem-solving. For example, the function f(x)=x3 is odd because f(−x) = −f(x). Odd functions are used to model phenomena that are symmetric with respect to the origin, such as alternating current in electrical engineering. Understanding odd functions helps in recognizing patterns and simplifying calculations in mathematical and real-world contexts.
