Sayfa 110 - Take out the logarithm of the given number from the table, and divide it by 2 for the square root, 3 for the cube root, &c. and the natural number answering to the result will be the root required. But if it be a compound root, or one that consists both of a root and a power, multiply the logarithm of the given number by the numerator of the index, and divide the product by the denominator, for the logarithm of the root sought. Observing, in either case, when the index of the logarithm...
Sayfa 110 - But if it be a compound root, or one that consists both of a root and a power, multiply the logarithm of the given number by the numerator of the index, and divide the product by the denominator, for the logarithm of the root sought. Observing, in either case, when the index of the logarithm is negative, and cannot be divided without a remainder, to increase it by such a number as will render it exactly divisible ; and then carry the units borrowed, as so many tens, to the first figure of the decimal...
Sayfa 22 - It is here also to be observed, that powers and roots of the same quantity, are divided by subtracting the index of the, divisor from that of the dividend. Thus, a 3 -r- a 2 , or -5 = 0; a 2 -r
Sayfa 113 - In what time will a sum of money double itself at 5 %, (a) at simple interest, (6) at compound interest, reckoned yearly i (72) If when wheat is 60s.
Sayfa 1 - ... the number below the line is called the denominator, and shows how many parts the quantity is to be divided into ; the number above the line is called the numerator, and specifies the number of such parts to be taken : — for example, let us take the following fractions...
Sayfa 29 - I)3 = {1 + (-I)8}114478742, where it is now reduced to a " Dual number ' ' in which the first 7 digits are ciphers. This type of number is a Dual Number of the Ascending Branch. Similarly, a number expressed as a product of powers of -9, -99, ... is a Dual Number of the Descending Branch. The transformation of a dual number of eight digits into another whose first seven digits are ciphers is termed "reducing a dual number to the eighth position," and a dual number reduced to the eighth position is...
Sayfa 1 - For 14 3 example: — , — , and — are all proper fractions and therefore less than 1. 25 n If the numerator is larger than the denominator, the fraction is called improper and is greater than 1 . For example: — , — , and — are all improper fractions and therefore greater than 1. An improper fraction can be converted into a mixed fraction by dividing its denominator into its numerator. For example, since 2 divides into 7 three times with a remainder of 1 , we get To convert a mixed...
Sayfa 107 - Ans. 413739 11. Divide .067859 by 1234.59, by logarithms. Ans. .0000549648 THE RULE OF THREE, OR PROPORTION, BY LOGARITHMS. For any single proportion, add the logarithms of the second and third terms together, and subtract the logarithm of the first from their sum, according to the foregoing rules ; then the natural number answering to the result will be the fourth term required. But if the proportion be compound, add together the logarithms of all the terms that are to be...
Sayfa 13 - France, which = 1076-42996 square feet English. The Stere is a cubic metre = 35-316582 cubic feet English. The Litre for liquid measure is a cubic decimetre = 1-76077 imperial pints English, at the temperature of melting ice ; a litre of distilled water weighs 15434 grains troy. The unit of weight is the gramme : it is the weight of a cubic centimetre of distilled water, or of a millilitre, and therefore equal to 15-434 grains troy. The kilogramme is the weight of a cubic decimetre of distilled water,...
Sayfa 103 - ... find, by means of the simple rules, before laid down for multiplication, division and the raising of powers, as many other logarithms as we please, or may speedily examine any logarithm in the table. MULTIPLICATION BY LOGARITHMS. Take out the logarithms of the factors from the table, and add them together ; then the natural number answering to the sum will be the product required. Observing, in the addition, that what is to be carried from the decimal part of the logarithms is always affirmative,...
