New functions RegionPlot and RegionPlot3D have been added to the built-in Mathematica kernel.
RegionPlot includes the functionality of InequalityPlot.
RegionPlot3D includes the functionality of InequalityPlot3D.
RegionPlot displays the two-dimensional region defined by a set of inequalities:
Version 5.2
![<< Graphics`InequalityGraphics`;
InequalityPlot[x^2 <= y^3 + y^2 - 5 y + 1, {x, -2, 2}, {y, -2, 2}]](Files/InequalityGraphics.en/legacy_1.gif)
RegionPlot3D displays the three-dimensional region defined by a set of inequalities:
Version 5.2
![InequalityPlot3D[
x^2 + y^2 + z^2 <= 1 && 3 x^2 + 3 y^2 <= z^2, {x, -1, 1}, {y, -1,
1}, {z, -1, 1}]](Files/InequalityGraphics.en/legacy_2.gif)
ComplexInequalityPlot was available in previous versions of Mathematica and is now available on the web at library.wolfram.com/infocenter/MathSource/6817.
