""Geometry, Algebra, and Trigonometry by Vector Methods"" is a comprehensive textbook written by Arthur Herbert Copeland. The book is designed to provide students with a thorough understanding of the fundamental concepts of geometry, algebra, and trigonometry using vector methods. The book is divided into three parts, each focusing on one of these subjects.Part one of the book covers the basics of geometry, including points, lines, angles, and polygons. The author uses vector methods to explain these concepts, making it easier for students to visualize and understand them. The section also includes a discussion on vectors and their properties.Part two of the book focuses on algebra, covering topics such as equations, functions, and graphs. The author uses vector methods to explain these concepts as well, making it easier for students to understand the relationship between algebra and geometry.Part three of the book covers trigonometry, including the properties of triangles, trigonometric functions, and identities. The author again uses vector methods to explain these concepts, making it easier for students to visualize and understand them.Throughout the book, the author provides numerous examples and exercises to help students practice and reinforce their understanding of the concepts presented. The book is suitable for students studying geometry, algebra, and trigonometry at the high school or college level.Allendoerfer Mathematics Series.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
