Conic Sections and Analytical Geometry: Theoretically and Practically Illustrated, written by Horatio N. Robinson and published in 1862, is a comprehensive guide to the study of conic sections and analytical geometry. The book is divided into two parts, with the first part covering the theoretical aspects of the subject and the second part focusing on practical applications.The theoretical section of the book begins with an introduction to the basic concepts of analytical geometry, including the Cartesian coordinate system and the equations of lines and curves. The author then delves into the study of conic sections, covering topics such as the definitions of ellipses, parabolas, and hyperbolas, their properties, and their equations. The section also includes a discussion of polar coordinates and their relationship to conic sections.The practical section of the book provides numerous examples and problems for students to work through, allowing them to apply the concepts they have learned in the theoretical section. The problems cover a wide range of topics, including finding the equations of conic sections given certain properties, determining the intersections of conic sections, and using conic sections to solve real-world problems.Overall, Conic Sections and Analytical Geometry: Theoretically and Practically Illustrated is a valuable resource for students and teachers of mathematics, providing a thorough and accessible introduction to these important topics.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
