a. Mathematics. In the Newtonian form of the infinitesimal calculus: ‘The rate or proportion at which a flowing or varying quantity increases its magnitude’ (Hutton Math. Dict.).This is Newton's own use of the word; but the 18th cent. writers on the Newtonian calculus used fluxion for what Newton called the ‘moment’ of a fluent, and modern analysts call the ‘differential’. corresponding fluxions, rates at which two interdependent quantities may change simultaneously. second fluxion, the rate of change of the fluxion of a variable quantity; the second differential coefficient with respect to the time.
