Wen-Feng, Try Plot[E^x, {x, 1, 4}] A small e has no special meaning or value in Mathematica, so e^x does not evaluated to a number. Capital E stands for the exponential constant. You can also use esc e e esc, or enter it from the BasicInput Palette. David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: Wen-Feng Hsiao [mailto:wfhsiao at libra.seed.net.tw] To: mathgroup at smc.vnet.net Dear experts, I have a trouble in plotting e^x. Plot[e^x, {x, 1, 4}] It keeps telling me: e^x is not a machine-size real number at x = 1.000000125 e^x is not a machine-size real number at x = 1.1217009747187472 e^x is not a machine-size real number at x = 1.2544263995781209; Even I have added the modifier "Evaluate". Plot[Evaluate[e^x], {x, 1, 4}] The output is the same. Please help! Thanks.
