To get a set of functions to plot, you would use solve(), like solve(Eq(x**2 + y**2, 1), y). This will return two solutions, which when plotted simultaneously, should give a full circle.
An easier way is to use plot_implicit(), which doesn't require solving, and will work even for equations that can't be solved by solve().
