I'm hoping someone can help me. I'm trying to find the equation of a circle using three points (2 outside points and the midpoint). I tried typing this from the Maple software help menu, but keep getting an error: > with(geometry); _EnvHorizontalName := m; _EnvVerticalName := n; > circle(c1, [point(A, 0, 0), point(B, 2, 0), point(C, 1, 2)], > 'centername' = O1); > center(c1), coordinates(center(c1)); Error, (in geometry:-circle) the coordinate names must be a list of two names Error, (in isassign) the first argument is expected of type name > My three points are actually (-4,-9), (6.7), and the center is (1,-1). I've worked on this for days, but can't seem to get anywhere. If anyone could help I'd greatly appreciate it! Thanks in advance!
