If you have version 7 of Mathematica you can use the MaxValue[] function if you want an exact value or just compute the second derivative zeros on any version of Mathematica. If you want an approximate value from the actual plot, use the "Graphics/Drawing Tools" menu and then pick the "Get Coordinates" icon (top right icon in the lower set of icons) and then move the cursor to the portion of the curve you want to see the values of (think this is in versions 6 and 7). -Bob
