Página 19 - To find then the logarithm of a vulgar fraction, subtract the logarithm of the denominator from that of the numerator. The difference will be the logarithm of the fraction. Or the logarithm may be found, by first reducing the vulgar fraction to a decimal. If the numerator is less than the denominator, the index of the logarithm must be negative, because the value of the fraction is less than a unit. ( Art* 9.) Required the logarithm of f 4.
Página 129 - From half the sum of the sides, subtract each side severally; multiply together the half sum and the three remainders; and extract the square root of the product.
Página 56 - A cylinder is a solid described by the revolution of a rectangle about one of its sides, which remains fixed.
Página 92 - One of the required angles is found, by beginning with a side, and, according to Theorem I, stating the proportion, As the side opposite the given angle, To the sine of that angle ; So is the side opposite the required angle, To the sine of that angle. The third angle is found, by subtracting the sum of the other two from 180° ; and the remaining side is found, by the proportion in the preceding article.
