Página vii - The logarithm of the product of two numbers is equal to the sum of the logarithms of the numbers.
Página vi - The characteristic of the logarithm of a number greater than unity is one less than the number of integral figures in that number.
Página viii - The logarithm of the quotient of two numbers is equal to the logarithm of the dividend minus the logarithm of the divisor.
Página xii - Hence we see that if we wish to divide one number by another, we have only to subtract the logarithm of the divisor from that of the dividend ; the difference will be the logarithm of their quotient. (4.) Since, in Briggs...
Página xv - 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.
