Extract

In Todhunter's Compound Interest (4th edition, chapters 8 and 9) several methods are given for the approximate determination of the rate of interest involved in a given transaction. In these methods there is no adequate treatment of the errors contained in the results. No simple means are given whereby the computer can tell to how many significant figures the results can be trusted.
