Analytic Geometry

By Gordon Fuller

This book is in good condition. There is minimal wear on the front, back, edges, and spine of the cover boards. There is almost no bumping and fraying on the cover boards. The pages are starting to yellow, but are not tanning, and the pages are clear of any markings. "For several centuries geometry and algebra developed slowly, bit by bit, as distinct mathematical disciplines. In 1637, however a French mathematician and philosopher, Rene Descartes, published his La Geometrie, which introduced a device for unifying these two branches of mathematics. The basic feature of this new process, now called analytic geometry, is the use of a coordinate system. By means of coordinate systems algebraic methods can be applied powerfully in the study of geometry, and perhaps of still greater importance is the advantage accuring to algebra by graphical representation of algebraic equations. Indeed, Descartes' remarkable contribution paved the way for rapid and far-reaching developments in mathematics, and analytic geometry continues to be of great value in mathematical investigations...." - Chapter One from Analytic Geometry

Descriptive Geometry

By Charles H. Schumann, C.E.

This book is in good condition. There is some wear on the front, back, edges, and spine of the cover boards. There is some bumping and fraying on the cover boards. The pages are yellowing and tanning, but there are no markings on the pages. There are some dog-eared pages. "Mathematics gives two methods for solving any problems, the analytical and the graphical. In the analytical method results are obtained by calculations; in the graphical by drawings which present true relationships and solutions without calculations. The solution of problems pertaining to space magnitudes by the graphical method requires application of the principles of Descriptive Geometry or the graphics of space. It is the theory of Drafting...." - Chapter One from Descriptive Geometry
