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}? Like all points in 2D space that satisfies >this equation? Equation? 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
