Calculator Guide

This guide is an introduction to the use of a graphing calculator.  It is
not a comprehensive guide.  The tools illustrated in this guide are
limited to the tools needed for Math 1314 with Integrated Technology.
The calculator references are to a Texas Instruments TI-84 Plus
graphing calculator.  The keystroke sequences should be similar on
other TI products, although some calculator features (such as key
colors) may differ.  Students using graphing calculators other than TI
calculators are advised to consult the user guide for their calculator
brand to make any necessary modifications to the keystrokes described
in this guide.  Most user guides are available online.
