Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator

Ok i had the same problem- If i remember correctly my "window" was messed up. Check it out... If not i always pull the "take batteries out while on" trick which resets the ram.

You have a syntax error in the function you're trying to graph. Could you post the function in question?

That hardly seems possible. Try graphing the function y=x.

There are a few ways to draw curves on this calculator

**Drawing Relations**

There are some other relation you can draw X=, X>, X< , and the drawing of general conics.

I hope that the foregoing remarks help you sort out the problem you are having. If they fail to do that, I suggest that you read the manual that shipped with your Prizm.

**Drawing functions**

- Type is y=f(X), the [X,theta, T] key enters X when pressed

- Type POLAR r=f(theta), key [X,theta, T] enters theta w. pressed.

- Type PARAMETRIC, requires an X=f(T) and Y=g(T) functions

- Inequality graphing. You can also draw some functional inequalities such as y> 2X^2-3
- Dynamic graphing (graphs where some parameter may be changing)

There are some other relation you can draw X=, X>, X< , and the drawing of general conics.

You do not say that you opened the Y= editor and typed in at least one function and THEN pressed Graph. If you do not enter a function, all you will get are the axes (if the calculator is configured to display the axes.

1. Open the Y= editor.

2. Type in a function EXample y=2X+1 (To type X press the [X,T, Theta, n] key)

3. Press ENTER to validate the function.

4. Press the GRAPH button.

5. If you do not see a straigt line press the ZOOM button

6. Select ZoomSTD

Press the Y= button.

There are several possibilities:

1) Scroll through all equations, Y1 through Y9 and Y0. Make sure they are cleared.

2) The equation you typed in is not entered correctly.

3) Make sure Plot 1, Plot 2, and Plot 3 are NOT highlighted.

If the message appears when you try to graph functions deactivate the
statistical plots. To do so:

Press [2nd][Y=] to access (STAT PLOTs)

Select [4:PlotsOff] then [ENTER]

That should solve your problem. Post a comment to this thread if you still have trouble graphing.If the message appears in another context, it sure would help knowing the context of the error.

Seems unlikely that you get a syntax error for both graphing and Zooming. Probably the error is in the function you are trying to graph.

To reset the RAM,

Press [2nd]MEM][7:Reset][1:All Ram][2:Reset] [ENTER]

Calculator answers with Ram Cleared.

Press [CLEAR] button to erase the above message.

Once Ram is cleared, open the [Y=] function editor and at the Y1= line, enter [X,T, theta, n] key or [ALPHA][X], to draw the simple function Y1=X.

If that works, that means your calculator is OK.

This usually happens after the statistical graphs have been used. You should deactivate them. Press [2nd][Y=] (STAT PLOT). Select [4:PlotsOff] [ENTER]. Calculator echoes Done on main screen.

Restart your graphs.

Press the 2nd Button then the ZOOM button. Make sure that AxesOn is highlighted. If not, move your cursor down until you on AxesOn and press ENTER.

If AxesOn is highlighted, then it is probably your window. Press ZOOM, then 6.

I think you should get a Texas Instruments calculator and push the 'y=' button then put the equation like '2x+4' in the y1 area. You can put the X by using the variable botton. I hope my english makes sense I am not a native speaker.

When I push the y= button on my calculator I get a ERR: SYNTAX message, any idea how to get around this?

thanks!
