I'm trying to graph nonlinear systems of inequalities. INEQUAL works only with linear systems. Someone in this forum suggested IMPLICITPLOT with the option FILLED = TRUE, but this doesn't always give the desired results since that option only gives the area between the curve and the x-axis a solid color. What I need is the power of OPTIONSFEASIBLE, OPTIONSEXCLUDED, OPTIONSOPEN, and OPTIONSCLOSED (options available with INEQUAL) that will work with nonlinear inequalities.
