Intersection
Posted:

Hello, I need help on solving this problem. How do you find the intersection(s) of 2 circumferences knowing only the center and the radius of each one? I have look on several book and on the internet without any success. The only way that come to my mind is to represent the circumferences with a system of equation: (x  a)^2 + (y  b)^2 = Rab^2 (x  c)^2 + (y  d)^2 = Rcd^2 where a,b,c and d are the coordinate of the centers and Rab and Rcd the radiuses; I think x and y values should be the coordinate of the intersection(s) point(s). Any help would be greatly appreciated.
