Synopsis

Excerpt from Treaties of Plane Trigonometry: To Which Is Prefixed a Summary View of the Nature and Use of Logarithms; Being the Second Part of a Course of Mathematics, Adapted to the Method of Instruction in the American Colleges

The section on right angled triangles in this treatise, may perhaps be considered as needlessly minute. The solutions might, in all cases, be effected by the theorems which are given for oblique angled triangles. But the applications of rectangular trigonometry are so numerous, in navigation, sur veying, astronomy, &c., that it was deemed important, to ren der familiar the various methods of stating the relations of the sides and angles; and especially to bring distinctly into View the principle ou' which most trigonometrical calculations are founded, the proportion between the parts of the given tri angle, and a similar one formed from the Sines, tangents, &c., in the tables.
