Help, My TI-83 / Ti-84 Won’t Graph

It can be 8 o’clock at evening. Evening meal is above. You might be sitting down down to look at a movie or Monday Evening Football — and then it comes about . . . “Mommmmmmmmm (or Daddddddddddd), my calculator isn’t really operating. I have to switch in my math research tomorrow, and my graph isn’t really demonstrating up.”

“This can’t be so poor”, you assume. “I passed substantial college math. Heck, I even mounted the Quicken Accounting Process at work. How complex can a calculator be?”

The final 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 procuring cart with on top of a pile three ring binders and notebook paper. It failed to glance so poor then, but now you choose a closer glance and there are all forms of keys you under no circumstances saw just before on a calculator. At the base is some thing acquainted — a standard hunting array of quantity keys, and at the right are the usual insert, subtract, multiply, and divide keys. But what the heck are “Manner”, “DEL”, “STAT”, “ZOOM”, “TRACE”, etcetera. ? What are you likely to do? Who ya gonna call?


Below are a few of definitely easy issues to do but try to remember, the title of this post is “Assist, My TI-83 / Ti-84 Will not Graph”, and that is definitely all that is addressed in this post.

The Graphing Buttons

Glimpse at the top row of buttons on the TI-83/TI-84 calculator. There should really be five of them, set apart from the other buttons and they should really have the next labels:

      [Y=]   [WINDOW]   [ZOOM]   [TRACE]   [GRAPH]

This is where by all of your exercise is likely to choose place.

The A few Important Complications

Most of the time when a graph is not exhibiting, there are three factors:

  1. Graph Perform.The graph perform is not entered properly, or not entered at all.
  2. Graph Not Turned On. The graph perform is entered properly, but graphing is not turned on.
  3. Viewing Window. The viewing window for the perform is set to the completely wrong sizing or spot.

We will offer with these a person at a time.

Examine that the Graph Perform is Entered Adequately

Thrust the [Y=] key at the top of the calculator. This puts you into the Y= editor monitor. You should really see a monitor that appears to be some thing like this:

Plot1 Plot2 Plot3

Y1= 2X+1






The expression “2X+1” is just an case in point, but you will need to see some form of expression in the Y= editor monitor, not just a bunch of blank “Y=” traces. If all you see is the next, then you will need to insert an expression:

Plot1 Plot2 Plot3







If you want to attempt a definitely easy expression to make guaranteed that the calculator can plot, use “Y1=X”. This should really plot a good 45 diploma line directly as a result of the origin of the graph monitor.

Examine that the Graph Perform is Turned On

It is achievable that graphing of the perform is not turned on in the Y= editor monitor. This error is a little little bit subtle. Glimpse at the “=” indication in the equation you are attempting to plot The “=” indication, will have to be highlighted.
If it is not, you will have to cursor to the “=” indication and push the [ENTER] key, to highlight it.

Viewing Window will have to be Set to Appropriate Size and Site

If the viewing window is set to the completely wrong sizing or spot, the calculator may possibly plot but you will never see it on the monitor.

There are a lot of methods to set the viewing window, but an straightforward reliable strategy is to just “Zoom Out”, until you see the perform you are attempting to graph. Thrust the [ZOOM] key at the top of the calculator. Then force “3” to zoom out. Repeat until you see the perform you are attempting to graph. Now you should really have some thought what window you will need to use to see the perform plotted. Thrust the [WINDOW] key at the top of the calculator and modify the display properties as required.
