I can email an image to anyone that wants it, or you can draw it like this...
I think this is what you want... Draw a point and a line vertically upwards of length R. Draw a large letter V (inverted cone) upwards from the point. Draw an arc, radius R to cut the V. Where the arc cuts the vertical draw a circle, radius r, to meet the edges of V. The edges of V are tangents. Draw radii to these tangents, making 90 degree angles with them. Mark r and R on the diagram. Now r/R = sin(A), where A is half the angle at the bottom of the V. Let's say there are n of these small circles, so that n*2*A = 360 (degrees) or n*2*A = 2*pi (radians) You can decide n and find A and then find r/R (the angles are usually in radians). You can then decide R and find r (or other way around). Each time through the loop for <=n the new angle measured from the vertical in a clockwise direction is n*2*A. The place to draw each circle is x=Rsin(n*2*A) and y=Rcos(n*2*A) Without geometry, where would we be? John pi=2.142 A=pi/n (in radians) r=R*sin(A) or R=r/sin(A) _______________________________________________ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
