PREFACE                                                              xvii



                Excel's Worksheet  Functions  and  Their  Arguments.  Worksheet
               functions are in  Arial font; the arguments are italicized.  Following Microsoft's
               convention, required arguments are in bold font, while optional arguments are in
               nonbold, as in the following:
                   VLOOKUP(/ookup-value, fab/e-array, column-index-num,  range-lookup)
                 The syntax of custom functions follows the same convention.


                Excel  Formulas.  Excel  formulas  usually  appear  in  a  separate  line,  for
               example,
                   =I +1/FACT(1)+1/FACT(2)+1/FACT(3)+1IFACT(4)+1/FACT(5)
               Named  ranges  used  in  formulas  or  in  the text are not  italicized,  to  distinguish
               them from Excel's argument names, for example,

                   =VLOOKU P(Temp,Table, MATCH( Percent, P-Row, 1 )+I,
                                                                     1
                                                                      )
               VBA  Procedures.       Visual  Basic  code  is  in  Arial  font.  Complete  VBA
                procedures are displayed in a box, as in the following.  For ease in understanding
                the code, VBA keywords are in bold.

                   Private Function Derivl (x)
                   'User codes the expression for the derivative here.
                   Derivl = 9 * x  2 + 10 * x - 5
                   End Function

                Problems and Solutions

                   There are over  100 end-of-chapter problems.  Spreadsheet solutions for the
                problems  are  on  the  CD-ROM  that  accompanies  this  book.   Answers  and
                explanatory notes for most of the problems are provided in Appendix 8.

                The Contents of the CD
                   The CD-ROM that  accompanies this book contains a number  of folders or
                other documents:
                   an  "Examples"  folder.   The  Examples  folder  contains  a  folder  for  each
                   chapter,  e.g.,  'Ch.  05  (Interpolation)  Examples.'  The  examples  folder  for
                   each  chapter  contains  all  of  the  examples  discussed  in  that  chapter:
                   spreadsheets, charts and VBA code.  The location of the Excel file pertinent
                   to each example is  specified in the chapter text, usually  in the caption of a
                   figure, e.g.,
                     Figure 5-5.  Using VLOOKUP and MATCH to obtain a value from a two-way table.
