# Math Help - New commands in Mathematica 7

1. ## New commands in Mathematica 7

Hi guys;

Does anyone know how to plot a complex inequality in Mathematica 7 ?, In previous version there was a command ComplexInequalityPlot.

Also, the new command to plot an inequality is RegionPlot, but there is a problem ? This new command need a lower and upper bound in plot ,i.e, {x,xmin,xmax}.On other hand , in previous version we could plot the inequlaity(ies) with specifying a constraints on bound such to let Mathematica to specify the region for inequality(ies) ??

During my search, I found the following website :

which contains a packages for complex plotting , but it doesn't work with me. Could anyone check please ?

Any help will be appreciated .

Thank you all

2. Hi. Don't see what the problem is. You can either load the (obsolete) package containing ComplexInequalityPlot, or just use RegionPlot:

<< GraphicsInequalityGraphics;
ComplexInequalityPlot[1/2 <= Abs[z] <= 1, {z}]
RegionPlot[1/2 <= Abs[z] <= 1 /. z -> x + I y, {x, -1, 1}, {y, -1, 1}]

3. I'm still beginner in Mathematica. What is the obsolete package about the order InequalitySolve . In fact, where can I find a packages with their commands ?

What about the package I put the link for it ? Does it work with you fine ?
