Paris: Chez de Bure Frères, 1829. First edition, very rare. Following his earlier textbooks, the Cours d’Analyse (1821) and Rćsumć des Leçons (1823), which provided the first rigorous formulation of the calculus of functions of a real variable, Cauchy in this work for the first time treats complex functions of.....

Paris: de Bure Frères, 1829. First edition, very rare, of Cauchy’s important memoir on the determination of the real roots of polynomial equations. As stated in the ‘Avertissement’, this is a (separately-paginated) offprint from Cauchy’s Exercises de Mathématiques, Quatrième Année, 1829 (journal pagination 65-128).
