Help, TI-83 / Ti-84 is not depicted

8 o'clock in the night. The dinner is over. You sit watching a movie or on Monday night football – and that happens. . . "Mommmmmmmmmm (or Daddddddddddd), my calculator does not work." My mathematical assignment tomorrow must be completed and my graph does not appear. "

" This can not be so bad, "you think." I graduated from high school mathematics. Heck, I also installed the Quicken accounting system.

Last time he looked at TI-83 or TI-84, he was in office superstore in August; at the beginning of a shopping trolley, on top of a pile of three ring binder and notebook papers. It did not look that bad, but now you look closely, and there are keys you've never seen before in the calculator. At the bottom there is something well known – the numeric buttons normally look for an array, and on the right is the usual addition, subtraction, multiplication and sharing of keys. But what about the "MODE", "DEL", "STAT", "ZOOM", "TRACE" etc.? What are you going to do? Who is calling?

Relax.

Graphic buttons

Refer to the top row of the TI-83 / TI-84 calculator buttons. It must be five separate from the other keys; and must have the following tags:

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

activity will take place.

The three main problems

The graph does not usually show up for three reasons:

1. Graphic Function Graph function is not properly specified or at all not listed.
2. The graph was not turned on. The graph function is correct, but the graph is not turned on.
3. View Window The function view window is set to wrong size or location.

We're dealing with them at once.

Make sure the graph function is set to

Press [Y =] at the top of the calculator. This will be displayed on the Y = Editor screen. You need to see a screen that looks like this:

Plot1 Plot2 Plot3

Y1 = 2X + 1

Y2 =

Y3 =

Y4 =

Y5 =

Y6 =

The term "2X + 1" is just an example, but a kind of expression on the Y = editor screen, not just a bunch of empty "Y =" lines. If all you see is the following, you need to add the following expression:

Plot1 Plot2 Plot3

Y1 =

Y2 =

Y3 =

Y4 =

Y5 = [19659002] Y6 =

If you really want to try a simple expression to make sure the calculator can draw, use "Y1 = X". Accordingly, you must draw a 45-degree line through the graph screen.

Check that the graphic function is turned on

It is possible that the graphic display of the feature will not turn on the Y = Editor screen. This bug is a bit delicious. Look at the "=" sign in the equation you want to draw The "=" sign should be highlighted.
If not, press the cursor to "=" and press [ENTER] to highlight it.

Window should be set to the correct size and location

If the viewing window is set to the wrong size or location, the calculator can be inserted but will not be visible on the screen.

Setting the viewing window is possible in many ways, but it is simply a reliable method to "Reduce" until the function you draw is displayed. Press the [ZOOM] button at the top of the calculator. Then press the "3" button to zoom out. Repeat until the curve you want to curve appears. Now you need to know what kind of window you need to use to depict the function. Press [WINDOW] at the top of the calculator and adjust the display characteristics, if necessary.
