Hi everyone, I appreciate the help given, but what I actually wanted was another way besides the suggestions made. Is there a way that mathematica can plot that function in any range, but that the plot is more explicity about critical points or local minima? To show graphically the local minima in a function, that has been optimized with FindMinimum Thanks in advance, Rebeca Begin forwarded message: > From: Rebeca Choy <rchoy at ula.ve> To: mathgroup at smc.vnet.net > Date: Mon Aug 18, 2003 09:58:34 US/Eastern > To: mathgroup at smc.vnet.net > Subject: [mg43277] How to evaulate a function and graph it > > Hi everyone, > > How can I evaluate a function of 2 variables, say: > > f(x,y) = x^4 + 3 x^2 + 5 y^2 + x + y > > in an interval of [-3.0,4.0] and[-3.0,4.3] for x and y? > > I need all the points between these two ranges to plot it > > > Thanks > > Rebeca > >
