极值 Maxima and minima

(重定向自Extremum)

在数学中,极大值与极小值(又被称为极值)是指在一个域上函数取得最大值(或最小值)的点的函数值。而使函数取得极值的点(的横坐标)被称作极值点。这个域既可以是一个邻域,又可以是整个函数域(这时极值称为最值)。

Maxima and minima 极值

(重定向自Extremum)
Local and global maxima and minima for cos(3πx)/x, 0.1≤ x ≤1.1
Peano surface, a counterexample to some criteria of local maxima of the 19th century
The global maximum is the point at the top

In mathematical analysis, the maxima and minima (the respective plurals of maximum and minimum) of a function, known collectively as extrema (the plural of extremum), are the largest and smallest value of the function, either within a given range (the local or relative extrema) or on the entire domain of a function (the global or absolute extrema). Pierre de Fermat was one of the first mathematicians to propose a general technique, adequality, for finding the maxima and minima of functions.
