Appendix A ? Using a Graphing Calculator

Section 1: Basic Computation

This appendix 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 Silver Edition 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.

This section contains an introduction to the hand-held calculator, as well as examples involving basic computation using the features of the graphing calculator.

Below the display screen are five buttons which access 10 different menus, each of which will be discussed in detail in this guide. These gray keys are labeled as follows: Y=, WINDOW, ZOOM, TRACE, and GRAPH. There are blue titles above these labels: STATPLOT, TBLSET, FORMAT, CALC, and TABLE. Many of the functions needed for this course will be accessed using these five keys.

Below these five keys and to the right are arrow keys that will move the cursor up, down, left or right. When looking at graphs, the left/right arrow keys will move the cursor to the left/right on the graph, and the up/down arrow keys will toggle between functions, if more than one function is graphed.
