Page 31 - How far will it fall in 16 seconds? 15. Find three quantities in arithmetical progression such that the sum of the squares of the first and third exceeds the second by 123, and the second exceeds one-third the first by 6.
Page 52 - ... positive roots, to include the first decimal place by Sturms' theorem. 2d. Then to find the decimal part of the first positive root, we arrange the co-efficients, and perform a succession of trans formations .by Synthetical Division, which must begin with the initial figures already known. We first transform the given equation into another whose roots shall be less by 1. The co-efficients of this new equation are, 1, 3, —4 and 1, and are all, except the first, marked by a star. The root of...
