2 (b - b) b,-c + c = 0, (5) 2 (a, - a.) a + 2 (6i - b.^ 6 - Ci + C2 = 0. (G) Equation (5) shows that the centers of the orthogonal systemSi - kySo = 0 lie in theradical axis of the sys-tem S—kS = 0; equa-tion (6) shows that thecenters of the systemS - kS = 0 lie in theradical axis of the sys-tem Si… … fiQ. 89. 100 ANALYTIC GEOMETRY tlie power of (0, ?/) is the same for all circles of the system,c must be a fixed constant. In like manner it is found thatthe equations of the orthogonal system Si — k^S^ — 0 have the form ar+^?/^-2 6i^ + Ci=0, {(3) where Cj is a fixed constant. The condition for the…
