This would mean t < t and t < -t + 1 The first inequality is always false, so the region you describe is empty. Do you actually mean to fill the region where y < x and y < -x+1? If that is what you are after, use RegionPlot. f[x_]=x g[x_]=-x+1 RegionPlot[{y < f[x] && y < g[x]}, {x, 0, 1}, {y, 0, 1}] -- Helen Read University of Vermont
