When in Trace mode, you can enter an X-value or an expression followed by
the
Enter key to re-position the graph cursor to a particular point on the graph. The X
entry and edit operations are announced. When the active cursor moves to a new X
location, the corresponding X- and Y-coordinates are announced.
"Y=" Menu
Pressing the Y= key will enter the "Y=" menu. The "Y=" menu is where you add the
expressions to be graphed. After the key is pressed, the "Y1" expression is spoken.
There are 10 graphs that can be plotted on the same screen; they are labeled "Y1" to
"Y0."
To navigate from one expression to the next, use the TI-84 Plus Up and Down
navigation keys.
If on the "Y1" and the TI-84 Plus Up key is pressed, the Plot menu is selected.
When in the Plot menu, moving left and right with the TI-84 Plus navigation keys
announces the status of the plot 1 through 3 and whether they are enabled and
disabled.
The following is announced with each "Y#" equation:
1. The equation string
2. If the equation is enabled or disabled
3. The style of the graph
You can navigate through various "Y=" equations by pressing the Up and Down
arrow keys on the TI-84 Plus. If the equation string is blank, only the equation number
(Y1 to Y0) is announced.
You can also navigate through an equation using the Left and Right arrow keys to
review the elements of an equation.
Enabling, Disabling, and Editing Equations
To enable or disable an equation, first select the equation, then press the TI-84 Right
arrow navigation key until the Orion says "cursor moved from equation to equals"
followed by the announcement of the status (either "enabled" or "disabled"). To toggle
the setting, press the
Enter key.
When in the equation section of the "Y#" editor, you can edit an equation the same as
you would on the Home screen.
