Then See also: A level surface, or , is the set of all points where some function has a given value.


The car slid down the steep gradient into the river.

The gradient of a f from the Euclidean space R n to R at any particular point x 0 in R n characterizes the best to f at x 0.

Consider a room where the temperature is given by a , T, so at each point x, y, z the temperature is T x, y, z , independent of time.

The gradient of F is zero at a singular point of the hypersurface this is the definition of a singular point.

A continuous gradient field is always a : its along any path depends only on the endpoints of the path, and can be evaluated by the gradient theorem the fundamental theorem of calculus for line integrals.

If the gradient of a function is non-zero at a point p, the direction of the gradient is the direction in which the function increases most quickly from p, and the of the gradient is the rate of increase in that direction, the greatest directional derivative.

The gradient admits multiple generalizations to more general functions on ; see.

Conversely, a continuous conservative vector field is always the gradient of a function.

Description: The gradient of H at a point is a plane vector pointing in the direction of the steepest slope or at that point.

The gradient of f is defined as the unique vector field whose dot product with any v at each point x is the directional derivative of f along v.
The magnitude and direction of the gradient vector are of the particular.
Consider a surface whose height above sea level at point x, y is H x, y.

    英文词源. gradient (n.) steep slope of a road or railroad, 1835, principally in American English, probably from grade (n.) by analogy of quotient, etc. [OED]. It was used 17c. as an adjective, of animals, characterized by walking; in that case it is probably from Latin gradientem, present participle of gradi to walk.

    梯度(gradient) 的概念. 在空间的每一个点都可以确定无限多个方向,一个多元函数在某个点也必然有无限多个方向。因此,导数在这无限多个方向导数中最大的一个(它直接反映了函数在这个点的变化率的数量级)等于多少?它是沿什么方向达到的?
