Because In particular: Thread Tools . Starting with the edition of 1857, the trigonometry section expands considerably, and Davies tells us that it was written by "Professor Church of the Military Academy, for publication as a separate work; but, under the impression that it would be more useful as a component part of a regular course, he generously offered it as a substitute for the Trigonometry of the previous Editions." Is it a good thing as a teacher to declare things like "Good! For example, most of Chapters X and XI are not relevant in a modern classroom (there is no reason for students to be taught how to read a log table, for example). \widehat {DXB}+ I am considering using S. L. Loney's Plane Trigonometry as the textbook for my course in trigonometry and would like to ask for opinions about the book. Therefore: $YG = 2XY=YV$.
