Coordinate Geometry (Classic Reprint) - Tapa blanda

Excerpt from Coordinate Geometry

The associative and commutative laws [alg.* 33, 69, 177] hold good for addition and subtraction as just defined. Hence, so far as addition and subtraction are concerned, the general rules of reckoning are the same for line segments as for numbers represented by letters.

Excerpt from Coordinate Geometry

In this book the several conics are treated early and in some detail, partly because of the value of a knowledge of their more important properties, partly because of the advantage, when presenting the analytic method to the student, of applying it in the first instance in the systematic study of a few interesting curves. In deference to usage, a chapter on the circle is introduced immediately after that on the straight line; but, if experience is to be trusted, it is better in a first course to proceed from the straight line directly to the parabola, so that, as early as possible, the student may get the impression which comes from seeing a method employed in the investigation of new material. The conics and the curves considered in Chapter XI afford illustrations of the study of locus problems by the method of coordinate geometry; and these illustrations are followed by a collection of exercises on loci in Chapter XII.

The part of the book devoted to solid geometry is more extended than is customary in elementary text-books; but it is desirable that the material here given should be easily accessible to students.

A pamphlet containing portions of the book has been in use at Princeton for three years. According to the experience thus gained, it should be possible for the better students to cover the text of the plane geometry, with the exception of Chapters III, VII, VIII, in a first-year course of three hours a week through half a year, and the remainder of the book in a second-year course of the same length.
