British Dictionary definitions for gradient

gradient

/ (ˈɡreɪdɪənt) /

noun

Also called (esp US): grade a part of a railway, road, etc, that slopes upwards or downwards; inclination

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

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

maths

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