奇函数定义为对于任意的x，满足f(x) = -f(-x)。这意味着在函数图像上，对于任何点(x, y)，其关于原点对称的点(-x, -y)也一定在图像上。奇函数的图像通常关于y轴旋转180度后与自身重合。偶函数则定义为对于任意的x，满足f(x) = f(-x)。这意味着对于任何点(x, y)，其关于y轴对称的点(-x, y)也一定在图像上。偶函
奇函数和偶函数(odd function and even function) 知乎用户f2iVZD 来自专栏 · 数学 3 人赞同了该文章 奇函数(odd function),定义为,任意f(x)=-f(-x)的函数,即为奇函数。 偶函数(even function),定义为,任意f(x)=f(-x)的函数,即为偶函数。 奇函数和偶函数在y轴上有一定的对称性。
Sine function: f(x) = sin(x) It is an odd functionBut an odd exponent does not always make an odd function, for example x3+1 is not an odd function.Neither Odd nor EvenDon't be misled by the names "odd" and "even" ... they are just names ... and a function does not have...
The two halves of an even function (split at the y-axis) mirror each other exactly. For an odd function, one side is upside-down from the other side.

Even and odd Functions in mathematics. The functiony=f(x) is said to be even if its value does not change when the sign of the independent variable changes—that is, iff(–x) =f(x). If, however,f(–x) =–f(x), then the functionf(x) is said to be odd. For example,y= cos...

Function Even, Odd, or Neither? $ f\left( x \right)=x$ Odd function: $ f\left( {-x} \right)=-f\left( x \right)$ $ \begin{array}{c}f\left( x \right)=x\\f\left( {-x} \right)=-x=-f\left( x \right)\end{array}$ Note that, as an example, both $ \displaystyle ...
