It can be 8 o’clock at night. Evening meal is around. You might be sitting down down to check out a film or Monday Evening Soccer — and then it transpires . . . “Mommmmmmmmm (or Daddddddddddd), my calculator isn’t functioning. I have to turn in my math research tomorrow, and my graph isn’t displaying up.”
“This cannot be so undesirable”, you believe. “I passed large college math. Heck, I even set up the Quicken Accounting Procedure at perform. How difficult can a calculator be?”
The last time you appeared at your child’s TI-83 or TI-84 was in August at the business office superstore it was in the entrance of a buying cart with on leading of a pile 3 ring binders and notebook paper. It didn’t glimpse so undesirable then, but now you acquire a closer look and there are all sorts of keys you never ever noticed prior to on a calculator. At the bottom is anything common — a regular searching array of selection keys, and at the proper are the common add, subtract, multiply, and divide keys. But what the heck are “Manner”, “DEL”, “STAT”, “ZOOM”, “TRACE”, and so forth. ? What are you heading to do? Who ya gonna call?
Take it easy.
Listed here are a couple of actually easy factors to do but don’t forget, the title of this short article is “Support, My TI-83 / Ti-84 Is not going to Graph”, and that is truly all that is tackled in this posting.
The Graphing Buttons
Search at the prime row of buttons on the TI-83/TI-84 calculator. There must be 5 of them, established aside from the other buttons and they must have the pursuing labels:
[Y=] [WINDOW] [ZOOM] [TRACE] [GRAPH]
This is where by all of your action is heading to consider location.

Plot1 Plot2 Plot3
The expression “2X+1” is just an illustration, but you need to have to see some form of expression in the Y= editor display, not just a bunch of blank “Y=” lines. If all you see is the following, then you need to increase an expression:
Plot1 Plot2 Plot3
If you want to try out a really simple expression to make certain that the calculator can plot, use “Y1=X”. This need to plot a awesome 45 diploma line specifically through the origin of the graph display.
Check out that the Graph Operate is Turned On
It is probable that graphing of the function is not turned on in the Y= editor monitor. This error is a little little bit delicate. Glance at the “=” indication in the equation you are making an attempt to plot The “=” indication, have to be highlighted.
If it is not, you will have to cursor to the “=” indication and push the [ENTER] key, to emphasize it.
Viewing Window will have to be Established to Right Sizing and Location
If the viewing window is established to the mistaken sizing or place, the calculator might plot but you won’t see it on the display screen.
There are lots of approaches to established the viewing window, but an quick trustworthy method is to simply “Zoom Out”, until you see the operate you are hoping to graph. Push the [ZOOM] vital at the prime of the calculator. Then press “3” to zoom out. Repeat right until you see the perform you are striving to graph. Now you should really have some concept what window you need to have to use to see the functionality plotted. Press the [WINDOW] essential at the major of the calculator and regulate the display features as essential.
