Newton's Method to Approximate a Zero of

                 f(x) = 5*exp(-x/3) - ln(x)

         Starting Value:      x0 = 3.5


          Iter#      x             f(x)

        This merely shows the results you SHOULD obtain on the first 1 iteration
        of PART I.

        You may have to display more decimal places than shown here,
        so follow the instructions in the assignment.
