My guess is that the OP wants to exert the maximum control over the procedures he is using. Sometimes Mathematica is "too smart" for the casual user. Most of the times the hidden work done by Mathematica is welcome, but sometimes it can be too 'invasive' and spoil the expectations of a user accustomed to less sophisticated software. Other instances of Mathematica doing some hidden work on behalf of the user could be the way N acts from version 3 onward. The adaptive increase in WorkingPrecision could lead to unexpected (albeit better) results if the user is not aware of this. (I want to make clear that I am not surmising that any of this is undocumented, only that the casual user might not be aware of those yet). As for the OP's question I'd say that a more 'conventional' way to plot a function graph without having Mathematica choosing the points is to create a vector of x-values, apply the function to them and then to use ListPlot with PlotJoined->True to show the line connecting the {x,y} pairs. cheers, Peltio -- Invalid address in reply-to.
