should every whole number that curve x crosses be taken into consideration when(adsbygoogle = window.adsbygoogle || []).push({});

constructing a polar graph? For example, when y=1 is crossed, should the radius be drawn

on the polar graph if the x value is not an exact, uh, pi number (for example instead

of .77 which is pi/4 the x value that curve x crosses 1 is at .88 or something like that)

To see what I mean, graph 3cosx and look where y=2 is crossed (at x=.84). Should I ignore this point?
