I have that two circles, but I do not know how to get points on the graph. var('x, y') ft = (x+1)^2-(y)^2-1 f=circle((-1,0), 1) p = plot(f,-5,5, thickness=2) @interact def _(r=(1..4)): g = circle((1,0), r) pt = plot(g,-5, 5, color='green', thickness=2) gt= (x-1)^2+ y^2-r pot = solve([ft,gt], x, y) html('$tocke=\;%s$'%latex(pot)) show( p + pt, ymin = -5, ymax = 4)  2014-09-26 03:24:54 -0500 received badge ● Student (source) 2014-09-25 10:36:03 -0500 commented answer Sage Notebook vs. Sage Cloud thank you! 2014-09-25 10:17:01 -0500 received badge ● Scholar (source) 2014-09-25 09:22:10 -0500 asked a question Sage Notebook vs. Sage Cloud What is the difference between Sage Notebook and SageCloud?
