LAGRANGE, JOSEPH LOUIS.

Nouvelle Methode pour Résoudre les Équations littérales par les moyen des Séries.

(Berlin, Haude et Spener, 1770). 4to. No wrappers as issued in "Mémoires de l'Academie Royale des Sciences et Belles-Lettres", tome XXIV, pp. 251-326. Clean and fine.

First edition of an importent paper in algebraic analysis. The method used by Lagrange was probably suggested to him by Lambert, and both Euler, Lexell, d'Alembert and Condorcet all became highly intereste in this discovery as soon as they heard about it. "Laplace later presented a better proof. Lagrange's formula occupied numerous other mathematicians, including Arbogast, Parceval, Servois, Hindenburg and Bürgman....; and virtually every analyst of the nineteenth century considered the problem." (Jean Itard in DSB). - Poggendorff I:1344.
