OF PLANE TRIGONOMETRY. BY WILLIAM SMYTH, A. M. PROFESSOR OF MATHEMATICS IN BOWDOIN COLLEGE. BOSTON. LILLY, WAIT, COLMAN, AND HOLDEN. Educt 168.34.795 HARVARD COLLEGE LIBRARY GIFT OF GEORGE ARTHUR PLIMPTON Entered, according to act of Congress, in the year 1834, by WILLIAM PRESS OF J. GRIFFIN, BRUNSWICK, ME. ADVERTISEMENT. In the following treatise the writer has endeavored to present the principles of plane trigonometry in a natural and connected order, to show the application of each principle as it is introduced, and in general to lead the student to feel the want of a new principle before proceeding to its investigation. The work has been prepared chiefly with reference to a college class, Regard has nevertheless been had to the wants of students in our public seminaries generally, in which trigonometry and its applications are taught. Several of the more recent treatises on trigonometry have been consulted in the course of the work; the most assistance however has been derived from those of Lacroix and Bezout. The Geometry referred to is that of Legendre in the Cambridge Mathematics. BOWDOIN COLLEGE, JAN. 1834. |
