graphing inequalities in 2 variables
Triggy,
You can plot your inequality on www.webgraphing.com. There, you will get both the plot of the curve and the region where the inequality holds. Just use the link to "Inequality Graphing in Two Variables." To represent |x|, use the notation abs(x).
LiveGraphicsD
Sure. Check out the website for LiveGraphics3D:
http://www.vis.uni-stuttgart.de/~kraus/LiveGraphics3D/
That is a source for software that works with Mathematica to produce 3D Interactive Graphs.
The quickest way is to use any of several Interactive 3D Graphing Calculators on WebGraphing.com. You can check out some examples of 3D :cool: function graphs at:

and follow the instructions to rotate, zoom in/out, spin, etc.
Complex Analysis with Mathematica
If you are serious, you might check out the book "Complex Analysis with Mathematica" by William T. Shaw, copyright 2006, Cambridge University Press. There you will find various ways to plot complex valued functions of a complex variable.
Complex-valued functions of a complex variable
So, you want to graph complex-valued functions of a complex variable. That involves a domain of two dimensions (x+iy) and a range of two dimensions (u+iv) . This is not for the faint of heart!
Give an example of a complex function!
It would be helpful if you gave an example of what you call a complex function. The term can be used is a variety of ways, so how you use it is important. For example, if you mean a complex-valued function of a real variable, then there are no graphing...
Online Graphing of Complex Functions
The website www.webgraphing.com plots complex functions with calculus analysis. Also, it is pretty easy to use.:smile: :smile:
