Hi Mathgroup,
	I have the x,y,z coordinates for a point in space at an 
initial position (req) and a change in that position (coordlist).
I want to watch that point move using the equations
	x(t)=x + delta x *Sin[w*t]
        y(t)=y + delta y *Sin[w*t]
	z(t)=z + delta z *Sin[w*t]

I tried by first identifying just one point,
                   {req[[1,1]]+coordlist[1][[1,1]] Sin[t],
                    req[[1,2]]+coordlist[1][[1,2]] Sin[t],
                    req[[1,3]]+coordlist[1][[1,3]] Sin[t]

then making a bunch of graphs

and then trying to animate the result using


among other things.

	Nothing works.  Can anyone offer a suggestion??
