the angle which this perpendicular makes with the prime radius. Thus inFig. 76, let M N be any line ; A, the pole ; AX, theprime radius ; the perpendicular from the pole upon theline, A D := p ; and the angle which the perpendicularmakes with the prime radius, DAX = a. Let P beany point in the line… … Fig. 76.
