You indicate ParametricPlot[{Sin[t], Cos[t]}, {t, 0, 2*[Pi]}] does what you want. This would be a circle centered at the origin. But in your initial statement you add another condition x + y = 1. This would be a line. Did you mean this condition to be x^2 + y^2 = 1 instead of what you posted? > > If the question is what other methods are available to plot a unit circle, then you could use ImplicitPlot or simply use the graphics primitive Circle. > > >E.g {(x,y) | 0 => x,y =>1}?

This looks like an inequality which would be satisfied by all of the points in the uppper left quadrant except for the strip 0 <= y < 1. > -- > To reply via email subtract one hundred and four > -- Hi Bill. Ofcourse it is x^2 + y^2 =1, my mistake. Thanks you all for replies. Regards, Ronny Mandal
