Actually, you can go to your graph, then hit 2nd PRGM, then under DRAW, 4: Vertical and place it wherever you want.

Hey faymalaka
what's up. ok so you can't do what you want to do. It just can't be done. I'm pretty sure it can be done on a casio. however, you can do it just not by graphing. (this is on your TI) ok so first go to 2nd ZOOM and turon off the Axes and the Expr. Then Go to 2nd Prgm. Then go to A or Pen. and you can draw. as long as you first go to pen then you can draw lines and circles and stuff like that. but you must first go to draw then pen. then a suggestion i would save it by hitting 2nd prgm then going right to STO. this allows you to save your drawins as like 1 or 2 or so one. and then if you want to start over from your last picture because you made a mistake just clrdraw and then start over by recalling it. THis is under the store function. by the way the pen turns on and off with the enter button. GOOD luck if you don't get it feel free to ask questions.

My TI-84 will graph but it will not show me the table of values. It just shows up blank.

Enter the function using the Y= editor. Pressing [ 2nd ][Graph] (table) will display the table. You can then press [GRAPH] to see the grapg. If you want both graph and table side by side use the split screen feature.
To do so press [Mode]. Scroll down to the last line Full Horiz G-T. Highlight the option G-T. Press the Graph key.

My TI-84 Plus won't let me graph trigonometric functions.

Is it somehow preventing you from graphing, or are you simply not getting the graph you expect?

Most likely you have the angular mode set wrong. You probably want it set to radians. Press MODE, move to the third line, highlight RADIAN, press ENTER, then 2ND [QUIT].

If it's not the angular mode, please reply to this post and give an example or two.

I have a TI-84 Plus and it will not graph two functions at once and I need it to do this for my Calculus homework.

I've had this problem as well. The calculator has a program running on it that will not allow 2 (or more) functions to graph at once. To solve this:

1. Hit the "APPS" button.
2. Scroll down the list (close to the bottom) and find the application called "Transfrm". Press enter.
3. Highlight "Uninstall" and press enter.

Your calculator should now be able to graph as many functions as you would like!
Hope this helps!

I want to graph a parabola on my ti-84. i entered the equation in y=, and then i turned on plot on, then i hit graph, but it is showing invalid dim. help please?

You're trying to graph a function that does not involve stat plot features but the calculator probably thinks you are. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

Im getting an err: invalid dim on my TI-84 Plus calculator...what do I do?

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.
