Question about Texas Instruments TI-84 Plus Calculator
I have tried all these steps and my calculator still displays a straight line?

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.

Press the 2nd button, then the plus button, the 7, then 1, then 2. This will reset your calculator.

SOURCE: graphing trig functions
Put the calculator in radian mode and it will graph trig functions just fine. If you don't know how to change it to radians, then go to mode and cursor over to select radians. I am assuming you know where the sine, cosine, tangent, etc. keys are.

More than likely, you've put in a number in the xmin or xmax that is not correct. Example....you put in an xmin of 10 and an xmax of -10 which would be backwards. This could also happen in the ymin or y max.
The easiest way to fix this is to press zoom 6 which wil get you back to the default graph of xmin of -10, xmax of 10 and ymin of -10 and y max of 10.
If you can't see your graph on this screen and need to change the window, just be sure the number in the min for both x & y is smaller than the number in the max. You change your window size by pressing the window button.

Turn the satistical plots OFF
Press [2nd][Y=] (STATPLOT). Select or enter 4: to execute the command [PlotsOff] [ENTER]
Clear the lists (statistical lists)
Press [2nd] (Catalog]. Press [PGRM] C. The cursor jumps to the first command in catalog that starts with C (The greek letters in names do not matter). Scroll down a bit to reach the command [ClrAllLists]. Select it and press [ENTER].
Try your graphs again.
If you still have problems, just reset the RAM:
Press [2nd][+] (MEM). Press 7 to select [Reset] then [1:All Ram][2:Reset]. Press [Clear] to erase the Ram Cleard message.
Now you should be able to draw the graphs.
Hope it helps.
Thanks for using FixYa.
