Newton's Method to Approximate a Zero of

                f(x) = ln(6/x) - 3*x*cos(x/4.5)

           Starting value:     x0 = 10.0


           Iter#        x          | f(x) |

          This merely shows the results you SHOULD obtain on the first 2 iterations
          of PART I.

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