                            Estimation and Limits -- A Graphic Approach

The following cell reminds you of the syntax for the Mathematica   Plot  procedure that you will want to use to draw graphs for this module.  Evaluate the next cell now.  The specification AspectRatio -> Automatic  causes Mathematica  to draw the graph so that one physical unit on the x-axis represents the same change in x as one physical unit on the y-axis represents for y.  This specification is optional but is nice to include in these graphs because we are interested in the relationship between the permissible error,  epsilon  and the tolerance, delta.  Since epsilon is plotted on the y-axis and delta is plotted on the x-axis this option makes it easier to compare epsilon and delta visually.
