Abstract
DR. J. C. P. MILLER has compiled these tables to facilitate the conversion of rectangular to polar co-ordinates, and after several years of experiment he is convinced that they afford the maximum efficiency. Acknowledgment is made of the advice and assistance of Dr. L. J. Comrie both in the computation and publication of the tables. A full description of the method of application with a computing machine and also with a slide rule is given, and, generally speaking, only one set-up of the machine or rule is necessary. Where maximum accuracy is essential, two settings are sometimes required with the slide rule, and examples are given which show the various degrees of accuracy that arise with one or two settings. The tables have already been extensively used in manuscript form for the transformation of harmonic constants a and b, obtained by harmonic analysis, to amplitude c and phase angle ɛ, in accordance with the relation c sin(nt + ɛ) = a sin nt + b cos nt.
