Side 64 - A sets out from a certain place, and travels at the rate of 7 miles in 5 hours ; and 8 hours...
Side 207 - ... cafe, it muft have been greater than each of an odd number of the pofitive roots. An odd number of the pofitive roots, therefore, muft lie between them when they give refults with oppofite figns. The fame obfervation is to be extended to the fubftitution of negative quantities and the negative roots. From this lemma, by means of trials, it will not be difficult to find the neareft integer to a root of a given numeral equation. This is the firft ftep towards the approximation ; and both the manner...
Side 222 - Iff a straight line be divided into any two parts, four times the rectangle contained by the whole line, and one of the parts, together with the square of the other part, is equal to the square of the straight line which is made up of the whole and that part.
Side 185 - The coefficient of the fourth term is the fum of all the products which can be made by multiplying together any three of the roots with their figns changed ; and fo of others.
Side 207 - ... that of the given abfolute term, the figns of an odd number of the pofitive roots muft have been changed. In the firft cafe, then, the quantity fubftituted muft have been either greater than each of an even number of the pofitive roots of the given equation, or lefs than any of them ; in the fécond cafe, it muft have been greater than each of an odd number of the pofitive roots.
Side 37 - JJ/xJV; hence, The sum of the logarithms of any two numbers is equal to the logarithm of their product.

Side 189 - From this transformation, the fecond, or any other intermediate term, may be taken away ; granting the refolution of equations. Since the coefficients of all the terms of the transformed equation, except the firft, involve the powers of e and known quantities only, by putting the coefficient of any term equal to o, and refolving that equation, a value of e may be determined; which being fubftituted, will make that term to...
