Rate of Change: The change in one quantity with respect to time is known as rate of change of quantity.
If a quantity y varies with another quantity x, satisfying y = (x), then represents the rate of change quantity with respect to x.
If x = (t) and y = ɡ(t), then = .
The value of at x = x0 i.e.
Change of y with respect to x at x = x0.
