Excerpt from Analytic Geometry: And Principles of Algebra The present work combines with analytic geometry a number of topics traditionally treated in college algebra that depend upon or are closely associated with geometric representation. Through this combination it becomes possible to show the student more directly the meaning and the usefulness of these subjects. The idea of coordinates is so simple that it might (and perhaps should) be explained at the very beginning of the study of algebra and geometry. Real analytic geometry, however, begins only when the equation in two variables is interpreted as defining a locus. This idea must be introduced very gradually, as it is difficult for the beginner to grasp. The familiar loci, straight line and circle, are therefore treated at great length. Simultaneous linear equations present themselves naturally in connection with the intersection of straight lines and lead to an early introduction of determinants, whose broad usefulness is most apparent in analytic geometry. The study of the circle calls for a discussion of quadratic equations which again leads to complex numbers. The geometric representation of complex numbers will present no great difficulty because the student is now somewhat familiar with the idea of variables, of coordinates, and even vectors (in a plane).

In view of the application to mechanics, the idea of the vector is given some prominence: and the representation of a func'tion of two variables by contour lines as well as by a.

In this book, the topics are presented in the same order as in the textbook. The problems concern two content areas: Linear Algebra, and Analytical Geometry. After reading this book, a student should be ables to solve linear equations and to perform the basic operations on numbers and algebraic expressions. The Linear Algebra tests will reveal readers' knowledge and skills, readers' abilities in interpreting symbols, justifying statements and constructing proofs. Readers should be able to apply the properties of determinants and matrix operations and solve linear systems of equations. The Analytical Geometry topics include different forms of equations of straight lines and planes; angles between simple figures; the curves of the second order. This book will prove definitive and ideal reference tool to research scholars, academicians and educationists.
