THE authors of this volume have taken for their aim the axiom that the best preparation for the calculus is a suitable course in co-ordinate geometry. The text is thus divided into two sections: the first, consisting of six chapters, is devoted to analytic geometry, and the second to the calculus. The former embraces both plane and solid geometry and deals not only with the conies, but also with cycloids, exponential and logarithmic curves, together with several curves of historical interest like the Cassinian Ovals. The section on calculus begins with a discussion of limits, continuity and derivatives. Then follows a sound exposition of integration, partial differentiation, multiple and line integrals, infinite series and finally a chapter on differential equations.Analytic Geometry and CalculusBy Prof. Max Morris Prof. Orley E.
