what i really want to ask is, what is the problem asking: - do o find the potential difference between for each charge? which pairs? - do i plot the potentials on a graph? -what do they mean "as a function of x along the x-axis"? are they talking about the x-axis of the graph I'm supposed to...

I picked up Mathematica 6.0 a couple days ago, so bear with me please. 1) Plot3D[{x^2 + y^2}, {x, -10, 10}, {y, -10, 10}] returns a blank graph whereas when I set the boundaries from 0 to 2 it returns the actual graph! Why isn't it working?2) When typing equation f into the Plot3D function(...

If I have a function from [0,1] to the complex plane, is there a way that I can plot it with Mathematica 6.0?

Just a thought... Pick a spot/location on the surface of the Earth. Now, the Earth is rotating on its axis and also rotating around the Sun (and wobbling a bit too). The sun and our solar system is rotating around our galaxy and our glaxy is moving in the universe as a whole. Is there...

Is there any way, in Mathematica, I can plot a straight line in a 3D plot environment? For example: Plot3D[{{y = 1 - x, z = y - 1}}, {x, -5, 5}, {y, -5, 5}] plots two surfaces, not their intersection (which is a straight line). Thank you in advance.

Among the demos at the gnuplot website, I saw this - http://gnuplot.sourceforge.net/demo/steps.1.gnu, but it does not make much sense to me. :( Could someone tell me how to plot step functions from the command line, just like you would the usual functions? Specifically, I'd like to plot...
