Differential coefficient; In mathematics, the limit of the gradient of a chord linking two points on a curve as the distance between the points tends to zero; for a function with a single variable, y = f’(x), it is denoted by f’(x), Df(x), or dy/dx, and is equal to the gradient of the curve.
A word that is derived from another word.
The derivative function senses the rate of rise or fall of the system temperature and automatically adjusts the cycle time of the controller to minimize overshoot or undershoot.
