Radian-Polar Paper. By E. M. Horsburgh, M.A. In this paper the angles are set out in radians and decimals of a radian.There is a conversion scale on the border of the paper which converts radiansto degrees, and conversely. In the first quadrant there are two semicircles ondiameters subdivided… … Fig. 8. paper, which may simplify the plotting of polar graphs. It is evident, too, thatthe various processes of graphic arithmetic may be illustrated by this paper,while reciprocals are given by the semicircle intercepting any ray. The paper is printed in two forms: fig. 8 represents the complete…
