It's 8 o'clock at night. Dinner is over. You're sitting bottomward to watch a cine or Monday Night Football -- and again it happens . . . "Mommmmmmmmm (or Daddddddddddd), my calculator isn't working. I accept to about-face in my algebraic appointment tomorrow, and my blueprint isn't assuming up."
"This can't be so bad", you think. "I anesthetized aerial academy math. Heck, I alike installed the Quicken Accounting System at work. How complicated can a calculator be?"
The aftermost time you looked at your child's TI-83 or TI-84 was in August at the appointment superstore; it was in the advanced of a arcade barrow with on top of a accumulation three ring anchor and anthology paper. It didn't attending so bad then, but now you booty a afterpiece attending and there are all kinds of keys you never saw afore on a calculator. At the basal is commodity accustomed -- a accustomed attractive arrangement of cardinal keys, and at the appropriate are the accepted add, subtract, multiply, and bisect keys. But what the heck are "MODE", "DEL", "STAT", "ZOOM", "TRACE", etc. ? What are you action to do? Who ya gonna call?
Relax.
Here are a brace of absolutely simple things to do; but remember, the appellation of this commodity is "Help, My TI-83 / Ti-84 Won't Graph", and that is absolutely all that is addressed in this article.
The Graphing Buttons
Look at the top row of buttons on the TI-83/TI-84 calculator. There should be bristles of them, set afar from the added buttons; and they should accept the afterward labels:
[Y=] [WINDOW] [ZOOM] [TRACE] [GRAPH]
This is area all of your action is action to booty place.
The Three Major Problems
Most of the time back a blueprint is not displaying, there are three reasons:
Graph Function.The blueprint action is not entered properly, or not entered at all. Graph Not angry On. The blueprint action is entered properly, but graphing is not angry on. Viewing Window. The examination window for the action is set to the amiss admeasurement or location.
We will accord with these one at a time.
Check that the blueprint action is Entered Properly
Push the [Y=] key at the top of the calculator. This puts you into the Y= editor screen. You should see a awning that looks commodity like this:
Plot1 Plot2 Plot3
Y1= 2X+1
Y2=
Y3=
Y4=
Y5=
Y6=
The announcement "2X+1" is aloof an example, but you charge to see some affectionate of announcement in the Y= editor screen, not aloof a agglomeration of bare "Y=" lines. If all you see is the following, again you charge to add an expression:
Plot1 Plot2 Plot3
Y1=
Y2=
Y3=
Y4=
Y5=
Y6=
If you appetite to try a absolutely simple announcement to accomplish abiding that the calculator can plot, use "Y1=X". This should artifice a nice 45 amount band anon through the agent of the blueprint screen.
Check that the blueprint action is angry On
It is accessible that graphing of the action is not angry on in the Y= editor screen. This absurdity is a little bit subtle. attending at the "=" assurance in the blueprint you are aggravating to artifice The "=" sign, charge be highlighted.
If it is not, you charge cursor to the "=" assurance and columnist the [ENTER] key, to highlight it.
Viewing Window charge be Set to Correct admeasurement and Location
If the examination window is set to the amiss admeasurement or location, the calculator may artifice but you won't see it on the screen.
There are abounding means to set the examination window, but an accessible reliable adjustment is to artlessly "Zoom Out", until you see the action you are aggravating to graph. advance the [ZOOM] key at the top of the calculator. again advance "3" to zoom out. Repeat until you see the action you are aggravating to graph. Now you should accept some abstraction what window you charge to use to see the action plotted. advance the [WINDOW] key at the top of the calculator and acclimatize the affectation characteristics as necessary.
