Página 8 - The characteristic of the logarithm of a number greater than unity is one less than the number of integral figures in that number.
Página 7 - As in the latter case, all the sines and cosines, all the tangents from o° to 45°, and all the cotangents from 45° to 90°, are less than unity (or i), the logarithms of these quantities have negative characteristics or indices.

Página 8 - If the value of the log sine, log cosine, &c., be given, and it is required to find the angle, we use the following 1°.
Página 3 - XXXII, page 50.) 2°. Add these together, the sum will be the logarithm of the product. 3°. Find from the Tables the corresponding number. (For the method of finding the corresponding number to a log., see pages 57 to 58.) This will be required product.
