etting the radius vector revolve in the nega-tive direction from AX, so that 6 is negative,we have for 0 = — 1 = OAa, r = Aa = 2 —^= h For 6 = — 2, r = 2-2 = 1 Thus, itappears that as the radius vector revolves in this direction it generates a portion ofthe spiral which at first rapidly approaches… … OHAPTEE m.
