Odd Functions. A function is "odd" when: −f(x) = f(−x) for all x. Note the minus in front of f(x): −f(x). And we get origin symmetry: This is the curve f(x) = x 3 −x. They are called "odd" because the functions x, x 3, x 5, x 7, etc behave like that, but there are other functions that behave like that, too, such as sin(x): Sine function ...

奇函数是指对于一个定义域关于原点对称的函数f（x）的定义域内任意一个x，都有f（-x）= - f（x），那么函数f（x）就叫做奇函数（odd function）。

2025年2月9日 · 在数学里，偶函数（英语： Even functions ）和奇函数（英语： Odd functions ）是满足着相对于加法逆元之特定对称关系的函数。 这在 数学分析 的许多领域中都很重要，特别是在 幂级数 和 傅里叶级数 的理论里。

2025年3月5日 · A univariate function f(x) is said to be odd provided that f(-x)=-f(x). Geometrically, such functions are symmetric about the origin. Examples of odd functions include x, x^3, the sine sinx, hyperbolic sine sinhx, tangent tanx, hyperbolic tangent tanhx, error function erf erf(x), inverse erf erf^(-1)(x), and the Fresnel integrals C(x), and S(x).

Understand whether a function is even, odd, or neither with clear and friendly explanations, accompanied by illustrative examples for a comprehensive grasp of the concept.

2025年1月13日 · In this article, we learn how to find the Fourier series of an even and of an odd Function. A function f (x) is called an even function if f (-x) = f (x) for all x. For example, f (x) = x 2 is an even function. If f (x) is an even function with period 2L over the interval [-L, L], then the formula of the Fourier series of f (x) is given by.

What Are Odd Functions? A function is called odd if for any x in its domain, the following holds: f (−x) = −f (x) ∀ x ∈ D f (− x) = − f (x) ∀ x ∈ D. The graph of an odd function is symmetric about the origin, meaning that for every point P (x, y), there’s an opposite point P (-x, -y). How Can You Tell If a Function Is Odd?
