| Abstract | Multiplication and division have in general been much more difficult to perform than addition and subtraction. Perhaps, if we could find some device for reducing multiplication and division to addition and subtraction, computational loads could be lightened. One such device is that of logarithms of course. This note outlines another such device with a brief outline of its history; that being the use of trigonometric tables to effect multiplication and division. The technique is called "prosthaphaeresis" a Greek word meaning addition and subtraction. We would not use this technique today because time has moved on and we have better, more advanced ways of calculating. However, in its time, it was a very practical way of doing difficult multiplication and division. It could receive mention in the upper secondary school when trigonometric identities are discussed to show their practical use in times past. (ERIC). |
