Hi,
what about
ContourPlot[y + Sin[x^2 + 3 y], {x, -3, 3}, {y, -3, 3},
ColorFunction -> Hue, PlotRangePadding -> None]
?
Cheers
Patrick

I can use Plot3D to plot a surface z as a function of x and y, say z = x^2-y^2, abd the NLP problem is to max or min z on some region defined by a function or functions such as:
x + y <= 12, x<=10, y <=10
I cannot seem to find a good way to plot the constraints, ie the extrusion of the region from the xy plane.
Help, anyone? TIA.

I would like to share an interesting point of view on Mathworld and
WRI.
I am legally blind and legally deaf (only 25%% left for sight and
hearing) and have some learning disabilities. However, my mind is
sharp, creative, and always willing to explore and learn.
Math is not...

Do you mean you're running Microsoft Word? Which version? I run MS Word 2007
concurrently with Mathematica on my Win7 64-bit OS quite frequently, and I
haven't run into any problems.

Hi Guys,
I am a newbie to mathematica..Is there anyway to read
values from 2 lists {n by 1} and {n by 1} to a new list {n by 2}
without using loops.. eg say you have x = {1,3,5} any y = {2,4,6}, I
will need a new list z ={{1,2},{3,4},{5,6}}.. Thanks in advance.

I have some spheres in a 3D display. Each sphere has a number.
Graphics3D[{{RGBColor[0.4, 1.0, 0.9, .2],
EdgeForm[Gray],
Table[Cylinder[{circls[[dx, 1]],
circls[[dx, 1]] + .01*circls[[dx, 3]]}, circls[[dx, 2]]],
{dx, 1, Length[circls]}]},
PointSize[0.015], Red, Point[taba1],
PointSize[0.015], Blue, Point[taba2],
Thickness[.003], White, Line[lines],
LightBlue, Sphere[coords, .6],
Yellow,
Table[Style[Text[xr, coords[[xr]]], FontSize -> imsize/30,
FontFamily -> "Arial Bold"],
{xr, 1, numbr}]},
Boxed -> False, ImageSize -> 800]
I notice two things that could be better:
1. The numbers do not get smaller on the more distant spheres. It would
be better if they had perspective like the spheres themselves do.

I have a list 'a' in which there are 'sets', and I want to reduce the list so that repeated patterns are eliminated.
Here is an example list:
a = {{x1, x2}, {x1, x4}, {x2, x3}, {x4, x5}, {x4, x6}, {x2, x7}, {x7,
x12}, {x3, x13}, {x13, x18}, {x6, x8}, {x5, x9}, {x9, x11}, {x9, x16}, {x8,
x10}, {x12, x14}, {x12, x15}, {x10, x17}, {x11...

Yes, I would still like to keep the center orientation.
