Textbook in PDF format

We have written this book with the aim of providing a modern course in analytic geometry for today’s students. The past decade has witnessed important changes in the textbooks used for the study of algebra, geometry, and trigonometry. It has become evident that the traditional course in analytic geometry should also be changed to reflect in spirit, as well as in content, the changes that have taken place in the study of mathematics.
This text is excellent preparation for the study of calculus and linear algebra. It is also an interesting course of and by itself. The material allows for a considerable amount of flexibility. Planned as a semester course, it might also be used in special cases as the basis for a full-year course. Also, several different semester courses are possible, depending on the preparation and aims of the students. The large number of exercises allows ample opportunity for adjustments in assignments, and the attention given to proof may be much or little. Asterisks signal those exercises which are particularly demanding.
Interest is secured at the outset by a study of the algebra and geometry of two-dimensional vectors, a topic new to many of the students. With this basis, vector methods can then be used in developing the concepts and techniques of analytic geometry. The student who continues his study of mathematics will find it very advantageous to have a working knowledge of vectors, and the material is inherently interesting even if one does not plan on future courses in mathematics.
An understanding of the traditional Cartesian methods, however, is still highly important to today’s students and, accordingly, we have been very careful to include a thorough treatment of these methods in tandem with the vector approach. We believe the course presented in this book gives students an unusual opportunity to see how two apparently diverse branches of mathematics are, in reality, closely related, and to appreciate the value of having more than one method available for solving a given problem.
Study aids include such valuable lists as key trigonometric identities, fundamental properties of real numbers, important symbols, and a summary of
formulas from analytic geometry. Color is used functionally to call attention to key concepts and processes and to clarify illustrative examples and diagrams.
Finally, students will enjoy the series of illustrated essays appearing at the close of chapters. These essays were included to deepen and extend the student’s interest in the subject and its applications.
