A slide show allows you to view the graphs of a sequence of transformations of a function. Each picture in the slide show displays one transformation, and you can run your slides in slow or fast motion. There is even a feature on the TI-84 Plus that allows the previous graphs in the slide show to remain on the screen.

To create a slide show of transformations of a graph, follow these steps:

1. Press [Y=] and highlight the equal sign of the function you plan to graph.

2. Access the Settings editor and highlight > for a slow slide show or highlight >> for a fast slide show.

Access the Settings editor with

The first screen shows that the Settings editor is set for a slow-motion slide show of the transformations of the graph of y = Asin(Bx + C) + D.

3. Enter the initial values of your variables A, B, C, and/or D.

4. Highlight the equal sign of the variable that you want to investigate.

5. Enter a value for Step, the step size.

6. Graph the function.

7. Enter a value for Max, the maximum value of the variable with the highlighted equal sign (that is, the value of that variable at the end of the slide show).

There are restrictions on the value you assign to Max. If it is too large, when you try to run your slide show, you get the ERR: Memory error message. To avoid this error message, the values assigned to Max, Step, and the variable with the highlighted equal sign should abide by the following inequality:

In the first screen,

is well below the maximum bound of 12.

8. Press [2nd][ZOOM] to display the Format menu. In the last line, highlight either TrailOff or TrailOn.

If you highlight TrailOff, your slide show will look like a motion picture with one transformation appearing on each slide. If you highlight TrailOn, the transformations from previous slides appear as dotted graphs while the graph of the current transformation appears as a solid graph.

If the option you want is not already highlighted, use the arrow keys to place the cursor on that option and press [ENTER] to highlight it.

9. Press [GRAPH] to start the slide show.

Before the show starts, you see a screen tallying the number of slides in your slide show. After completing the slide show, the calculator keeps rerunning it until you press [ON] or [ENTER], as explained in the next step.

If you do get the ERR: MEMORY error message, reduce the value assigned to Max and/or increase the value assigned to Step and/or increase the value assigned to the variable with the highlighted equal sign.

10. Press and hold [ON] to terminate the slide show.

After pressing [ON] the Setting editor appears so that you can, if you wish, make changes in this editor.

If you want to pause the slide show, press [ENTER]. A moving dotted line appears in the upper-right corner. To resume the show, press [ENTER] again.
