&This diskette contains 12 interactive tutorials designed by F.P. Beer and E.R. Johnston, Jr., to complement their text. The software was prepared by Professor Ray Canale and Tad Slawecki of the University of Michigan, and Professor Steven Chapra
of the University of Colorado.
&To use these tutorials, follow the directions at the bottom of the screen. A list of special-purpose keys in the tutorials can be displayed by pressing [F1].
