Can anyone explain to me why Graphs #5 and #6 (please see below) do not include any output for x < 0 and x < -1, respectively? Thanks! Jim Kochanski Following graphs are plotted from x = -10 to x = 10 Graph #1 : Plot[Cos[x], {x, -10, 10}] Graph #2 : Plot[Cos[x + 1], {x, -10, 10}] Graph #3 : Plot[Cos[x^3], {x, -10, 10}] Graph #4 : Plot[Cos[x^3 + 1], {x, -10, 10}] Following graph is only plotted from x = 0 to x = 10 Graph #5 : Plot[Cos[(x^3)^(1/3)], {x, -10, 10}] Following graph is only plotted from x = -1 to x = 10 Graph #6 : Plot[Cos[(x^3 + 1)^(1/3)], {x, -10, 10}]
