Hi, I don't think that there is a built-in function, but you can use Solve to find the intersection: intersection[x1_, y1_, r1_, x2_, y2_, r2_] := Module[{x, y}, {x, y} /. Solve[(x - x1)^2 + (y - y1)^2 == r1^2 && (x - x2)^2 + (y - y2)^2 == = r2^2, {x, y}]] Norbert On Dec 21, 4:01 am, Felix <f.be... at gmx.de> wrote: > Hey, > I m already hours busy with trying to find a way to indicate the coordinates of the point(s) where two circles intersect. > Does Mathematica have a function that gives me the points of intersection if my input are the coordinates (in 2D) and the radii. > Thanks, > > Felix
