7. (Mathematics) maths
a. Also called: differential coefficient or first derivative the change of a function, f(x), with respect to an infinitesimally small change in the independent variable, x; the limit of [f(a + Δx)–f(a)]/Δx, at x = a, as the increment, Δx, tends to 0.

## de·riv·a·tive

(dĭ-rĭv′ə-tĭv)
In calculus, the slope of the tangent line to a curve at a particular point on the curve. Since a curve represents a function, its derivative can also be thought of as the rate of change of the corresponding function at the given point. Derivatives are computed using differentiation.
