My apologies if this has been posted before, but a quick search didn't turn it up. I'd like to have a simple, "clickable" way, preferably in the "PlotBuilder", to shade in the region *between* two 2D curves or two 3D surfaces. I know that there are packages to do this, but I'd like my students to be able to do it without learning any new commands or loading any new packages --- it's just too useful when you are teaching calculus. Thanks for listening! ----Josh

Under Maple 10, the command densityplot(10-x-y, x = 0 .. 3, y = -x .. x, scaling = constrained, colorstyle = HUE, style = patchnogrid)
