Encyclopedia Article for fluxion

in mathematics, the original term for derivative (q.v.), introduced by Isaac Newton in 1665. Newton referred to a varying (flowing) quantity as a fluent and to its instantaneous rate of change as a fluxion. Newton stated that the fundamental problems of the infinitesimal calculus were: (1) given a fluent (that would now be called a function), to find its fluxion (now called a derivative); and, (2) given a fluxion (a function), to find a corresponding fluent (an indefinite integral). Thus, if y = x3, the fluxion of the quantity y equals 3x2 times the fluxion of x; in modern notation, dy/dt = 3x2(dx/dt). Newton's terminology and notations of fluxions were eventually discarded in favour of the derivatives and differentials that were developed by G.W. Leibniz. See also calculus
