Most users will now have the second or subsequent printing of this text. A number of corrections were made at the second printing that are not listed here. The list below gives corrections that will be made in the third or later printings. To report additional corrections or make other suggestions for subsequent printings, contact wolfson@middlebury.edu.

Note to Macintosh users of the Instructor's Solutions Manual CD:

Users of the Macintosh Word version of the Instructor's Solutions Manual on CD may have trouble printing solution sets with material taken from the CD. The difficulty is in the equations, which were evidently set with MathType in a windows environment. They must be updated before they'll print correctly from a Mac. The procedure described below accomplishes this; unfortunately, it's only available if you have MathType installed on your Mac and set up to work with Microsoft Word.

To update equations, have your Word document (not the file from the CD) as the active document. Choose "Update Equations" from Word's "Tools" menu. Make sure the "Range" selection is set to "Whole document," then click "Update." The process may take a few minutes. You should then be ready to print.
