Derivative

n. conjugate (Grammar); by-product, offshoot

adj. obtained from another source, derived, borrowed

In calculus, a branch of mathematics, the derivative is a measurement of how a function changes when the values of its inputs change. Loosely speaking, a derivative can be thought of as how much a quantity is changing at some given point. For example, the derivative of the position of a car at some point in time is the velocity, or speed, at which that car is traveling (conversely the integral of the velocity is the car's position or distance traveled).
