Traite Coniques - HOSPITAL (Guillaume François Antoine, Marquis de l’) TRAITÉ Analytique des Sections Coniques et de Leur Usage pour la Resolution des Equations dans les Problêmes tant déterminez qu’indéterminez . A Paris: Chez Montalant, 1720. 4.º; a, A-Z, Aa-Zz, Aaa-Lll4, Mmm2; [8], 460, 34 gravuras: il.; 265 mm. SECOND edition, revised and enlarged, of the important posthumous treatise in which the Marquis de l'Hospital systematizes the theory of conic sections, conceived as an extension of Descartes' Geometry and which remained, throughout much of the 18th century, a reference work on the subject. In it, the author rigorously expounds the properties of the ellipse, parabola, and hyperbola, combining classical geometric methods with algebraic analysis to solve determinate and indeterminate problems, illustrating the text with numerous fold-out engraved plates. A disciple of Johann Bernoulli and one of the central figures in the dissemination of infinitesimal calculus in Europe, l'Hospital gives here one of the first complete and influential presentations of the analytical geometry of conic sections.
