Help, my TI-83 / Ti-84 won't draw

It's at 8 o'clock at night. Dinner is over. You sit down to watch a movie or Monday night football – and then it happens. . . "Mommmmmmmmmm (or Daddddddddddd), my calculator doesn't work." I have to turn my homework homework tomorrow and my dig does not appear. "

" This can't be so bad, "you think." I went to elementary school. Heck, I even put up Quicken Accounting System at work.

The last time you visited your child TI-83 or TI-84 was in August in office space. it was in front of a shopping cart with a top of a pile of three bindings and a notebook card. It wasn't that bad but now you look more closely and there are all kinds of keys you never saw before on a calculator. At the bottom is something that is familiar – the ordinary look of the number of keys, and the right side is the ordinary addition, subtraction, multiplication, and division keys. But what the hell are "MODE", "DEL", "STAT", "ZOOM", "TRACE" etc.? What are you going to do? Who are you going to call?

Relax.

Here are some very simple things to do; but remember, the title of this article is "Help, TI-83 / Ti-84 won't grab", and that's really all that is discussed in this article.

Graph buttons

Look at the top of the keys on the TI-83 / TI-84 calculator. There should be five of them, set apart from the other buttons; and they should have the following signs:

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

This is where your all activity is going to occur.

Three main problems

Most of the time a graph is not shown there are three reasons:

  1. Photography. The buried function is not entered correctly or is not entered overall.
  2. The picture is not taken into use. The graphics processing is entered correctly, but the dig is not turned on.
  3. View window. View the window for the operation is set to the wrong size or location.

We will deal with this at once.

Make sure the graph is correct

Press the [Y =] key at the top of the calculator. This puts you in the Y = editor screen. You should see a screen that looks like this:

Plot1 Plot2 Plot3

Y1 = 2X + 1

Y2 =

Y3 =

Y4 =

Y5 =

Y6 = [19659002] The expression "2X + 1" is just an example, but you need to see some kind of expression on the Y = editorial screen, not just a lot of blank "Y =" lines. If all you see is the following then you need to add expression:

Plot1 Plot2 Plot3

Y1 =

Y2 =

Y3 =

Y4 =

Y5 =

Y5 =

Y6 =

If you want to try very simple expressions to make sure the calculator can use the weights "Y1 = X". This should land a decent 45 degree line directly through the origin of the image display.

Make sure the graphing mode is active.

It is possible that the graph is not switched on in the Y = editorial view. This error is a bit subtle. Look at the "=" icon in the equation you are trying to land. "=" Sign, must be identified.
If it is not, you must click the "=" icon and press the [ENTER] key to identify it.

View window must be set to the correct size and location

If the viewing window is set to the wrong size or location, the calculator may be vertical but you will not see it screen.

There are many ways to configure the viewing window, but an easy reliable method is simply "Zoom Out" until you see the action you're trying to view. Press the [ZOOM] key at the top of the calculator. Then press "3" to zoom. Repeat until you see the action you're trying to view. Now you should have an idea of ​​which window you need to use to see the feature demolished. Press the [WINDOW] key at the top of the calculator and adjust the display properties as needed.
