LACROIX, Sylvestre François (1765–1843). Traité du calcul différentiel et du calcul intégral. [Vol III:] Traité des différences et des series. Faisant suite au Traité du calcul différentiel et du calcul intégral. Paris: J.B.M. Duprat, 1797-1800

First edition, a fine uncut large-paper copy, of Lacroix’s classic treatise on the calculus, in which he “united all the scattered methods, harmonized them, developed them, and joined his own ideas to them ... This monumental work constituted a clear picture of mathematical analysis, documented and completely up to date. While Lacroix followed Euler on many points, he incorporated the various advances made since the middle of the eighteenth century. The treatise is a very successful synthesis of the works of Euler, Lagrange, Laplace, Monge, Legendre, Poisson, Gauss, and Cauchy" (DSB).

Three volumes, quarto (300 x 225 mm). Half-titles in volume 2 & 3; 9 folding plates and tables. Contemporary quarter marbled calf and marbled boards (some minor rubbing).
