Page viii - Logarithms (Briggs's) are the only ones used to facilitate extensive numerical calculations. In this system, the logarithm of a number is the index of that power of 10 which is equal to the number. If for example a and b are the logarithms of the numbers A and B, we have 10...
Page xvi - From 0 to 45° the degrees are placed at the top of the page; the minutes and seconds, denoted with ' and " on the left hand margin, which is to be combined with the heading at the top of the page. From 45° to 90° the degrees are put at the bottom of the page, the minutes and seconds at the right hand margin, and the name of the trigonometrical function at the foot of the column. Arguments that are opposite one another are complementary (ie make together 90°) and the sines and tangents (ie...
