Excerpt from Elements of Geometry, Conic Sections and Plane TrigonometryThe volume commences with a brief Sketch of the history of Elementary Geometry, which, it is hoped, may increase the stu dent's interest in a subject which has occupied the attention of SO many gifted minds. The definitions of Book I. Have been somewhat amplified, for the purpose of giving clearer ideas of the philosophy Of the subject, and several notes have been add ed to the first pages of the book which, it is hoped, may be found useful and suggestive, although they are generally such as any competent teacher might easily have supplied.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
