Elements of Geometry: Conic Sections, and Plane Trigonometry is a comprehensive textbook written by Elias Loomis and first published in 1895. The book covers a wide range of topics in geometry and trigonometry, including conic sections, plane geometry, and plane trigonometry. The first part of the book focuses on conic sections, which are curves that result from intersecting a plane with a cone. The author explains the properties of conic sections, including ellipses, parabolas, and hyperbolas, and provides numerous examples and exercises to help readers understand these concepts.The second part of the book covers plane geometry, which deals with the properties and relationships of points, lines, angles, and figures in two dimensions. The author explains the basic principles of plane geometry, including Euclidean geometry, and provides examples and exercises to help readers develop their problem-solving skills.The final part of the book covers plane trigonometry, which is the study of the relationships between the sides and angles of triangles. The author explains the basic principles of trigonometry, including the sine, cosine, and tangent functions, and provides examples and exercises to help readers apply these concepts to real-world problems.Overall, Elements of Geometry: Conic Sections, and Plane Trigonometry is a comprehensive textbook that provides a thorough introduction to the principles and applications of geometry and trigonometry. It is suitable for students and teachers of mathematics, as well as anyone interested in these subjects.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
