The ERR:INVALID DIMENSION error message may occur if you are trying to graph a function that does not involve the stat plot features. The error can be corrected by turning off the stat plots.
Window range error or zoom error. Change the window parameters (Xmin, Xmax, Ymin, Ymax) so that the window is larger or smaller, depending on the graph. Change the input to a valid value. Requested zoom has invalid results.
The Restore tool can be accessed by clicking the Restore icon on the TI Connect Home screen. When the Restore icon is clicked, a window opens, prompting you to select the location where the Backup data was saved on your computer.
To put most models of scientific calculators in degree mode, all you have to do is press "Mode" and then look at the numbers on the screen beside the menu items. Locate the number beside "Deg" or "Degrees" and press it to change the mode of your calculator.
Defaults: Restores the default factory settings to all system variables, including the mode settings. ALL RAM: All your programs and data stored in RAM will be erased. In addition, the default factory settings are restored.
Q: How can I completely reset my TI 83 or TI 83 Plus back to the factory default settings?
- Press 2nd MEM (that is the second function of the + key)
- Choose 7 (Reset)
- Scroll right so that ALL is selected.
- Press 1.
- Press 2 (Reset, and read the warnings)
How to Clear the Memory on a Scientific Calculator
- Press the "MEM" key by pressing the yellow "2nd" key, then pressing the "+" key.
- Select "Reset" from the menu that appears and press "Enter."
- Choose whether to clear "All Memory" or "Just Defaults."
- Warning. Erasing "All Memory" will also delete any downloaded games.
Zoom In and Zoom Out commands on the TI-84 PlusThen press [ENTER]. The graph is redrawn centered at the cursor location. You can press [ENTER] again to zoom in closer or to zoom out one more time. Press [CLEAR] when you're finished zooming in or zooming out.
If you don't see your function graph anywhere, your window is probably set to a region of the xy plane the graph just doesn't happen to go through. You can try to zoom out (like going higher to see more of the plane) by pressing [ ZOOM ] [ 3 ] [ ENTER ]. If you need to, press [ ENTER ] again to zoom out further.
To automatically generate a table, perform the following steps:
- Highlight the equal sign of those functions in the Y= editor that you want to appear in the table.
- Press [2nd][WINDOW] to access the Table Setup editor.
- Enter a number in TblStart, and then press [ENTER].
- Enter a number in.
To find the domain, we simply solve the equation y=f(x) y = f ( x ) to determine the values of the independent variable x . To calculate the range of the function, we simply express x as x=g(y) x = g ( y ) and then find the domain of g(y) .
TI-84: Setting Up a Scatter Plot
- Go to [2nd] "STAT PLOT". Make sure that only Plot1 is ON.
- Go to Y1 and [Clear] any functions.
- Go to [STAT] [EDIT]. Enter your data in L1 and L2.
- Then go to [ZOOM] "9: ZoomStat" to see the scatter plot in a "friendly window".
- Press [TRACE] and the arrow keys to view each data point.
If you get the ERROR: WINDOW RANGE error message when graphing functions, this is most likely caused by setting Xmin greater than or equal to Xmax or by setting Ymin greater than or equal to Ymax in the Window editor.
