EXCERPT: AUTHORS' FOREWORD - A Modern Analytic Geometry is the outgrowth of discussions held by the authors while engaged in marking Grade 13 Geometry departmental examinations. The present work reflects their view that a new approach might be an aid in promoting a better understanding of the subject in these days of change in mathematical thought. This book is less than revolutionary in its forward move, but the influence of modern mathematics is apparent. For example, the traditional "moving point" concept of locus is blended with the notion of sets in the hope that students will acquire a more complete understanding of the concepts involved. Each of the conic sections is considered before tangents and diameters are fully introduced to make possible a saving of time and to assist in effective review . . . Size: 8vo - over 7¾" - 9¾" tall.
