## gradient

(ˈɡreɪdɪənt)*n*

**1.**(Civil Engineering) Also called (esp US):

**grade**a part of a railway, road, etc, that slopes upwards or downwards; inclination

**2.**(Civil Engineering) Also called (esp US and Canadian):

**grade**a measure of such a slope, esp the ratio of the vertical distance between two points on the slope to the horizontal distance between them

**3.**(General Physics)

*physics*a measure of the change of some physical quantity, such as temperature or electric potential, over a specified distance

**4.**(Mathematics)

*maths*

**a.**(of a curve) the slope of the tangent at any point on a curve with respect to the horizontal axis

**b.**(of a function,

*f*(

*x, y, z*)) the vector whose components along the axes are the partial derivatives of the function with respect to each variable, and whose direction is that in which the derivative of the function has its maximum value. Usually written: grad

**f**, ∇

*f*or ∇

**f**. Compare curl

^{11}, divergence

(ˈgreɪ di ənt)*n.*

**1.**the degree of inclination of a highway, railroad, etc., or the rate of ascent or descent of a stream or river.

**2.**an inclined surface; grade; ramp.

**3.**

**a.**the rate of change with respect to distance of a variable quantity, as temperature or pressure, in the direction of maximum change.

**b.**a curve representing such a rate of change.

**4.**a differential operator that, operating upon a function of several variables, results in a vector whose coordinates are the partial derivatives of the function.

## gra·di·ent

(grā′dē-ənt)**1.**The degree to which something inclines; a slope. A mountain road with a gradient of ten percent rises one foot for every ten feet of horizontal length.

**2.**The rate at which a physical quantity, such as temperature or pressure changes over a distance.

## gradient

The rate of inclination to horizontal expressed as a ratio, such as 1:25, indicating a one unit rise to 25 units of horizontal distance.
