I have strange problem with Wolfram Mathematica's function RegionPlot
RegionPlot[x - y == 0, {x, 0, 100},Mathematica's function {y, 0, 100}]RegionPlot
RegionPlot[x - y == 0, {x, 0, 100}, {y, 0, 100}]
the result is:
But when I try
RegionPlot[x - y == 1, {x, 0, 100}, {y, 0, 100}]
RegionPlot[x - y == 1, {x, 0, 100}, {y, 0, 100}]
Do you know what I am doing wrong? Thanks!
