It is 8 o'clock at night. Dinner is over. You sit down to watch a movie or monday night football – and then it will happen. . . "Mommmmmmmmmm (or Daddddddddddd), my calculator does not work." I have to turn my homework home tomorrow and my grave does not appear. "
" This can not be so bad, "you think." I went to elementary school. Heck, I even installed Quicken Accounting System at work.
The last time you visit your child TI-83 or TI-84 was in August in the office building; It was in a shopping cart on top of a pile of three circles and a notebook card. It was not that bad but now you look further and there are all sorts of keys you never saw before on a calculator. At the bottom is something familiar – the usual look of the number of keys, and the right side are the usual addition, subtraction, multiplication and partitioning of keys. But what are the modes "MODE", "DEL", "STAT", "ZOOM", "TRACE" etc.? What are you going to do? Who are you going to call?
Here are some very simple things to do; but remember, the title of this article is "Help, TI-83 / Ti-84 will not catch", and that's really all that is discussed in this article.
The Graph Buttons
See the top of the buttons on the TI-83 / TI-84 calculator. There should be five of them, apart from the other buttons; and they should have the following signs:
[Y =] [WINDOW] [ZOOM] [TRACE] [GRAPH]
This is where all yours functionality is going to take place.
Three main problems
Most of the time not shown is three reasons:
- Photography. The graph function is not entered correctly, or not at all.
- The image is not taken into use. The graph process is entered correctly, but the graph is not turned on.
- View window. View the window for the operation is set to the wrong size or location.
We will deal with these 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
19659002] The expression "2X + 1" is just an example, but you need to see some form of expression on the screen Y = editor, not just a lot of blank "Y =" lines. If all you see is the following, you need to add an expression:
Plot1 Plot2 Plot3
If you want to try a very simple expression to make sure that the calculator can use the word "Y1 = X". This should be a vertical nice 45 degree line directly through the origin of the screen.
Make sure the graphite engine is active
It is possible that the graph is not enabled on the Y = editor screen. This error is a bit subtle. Look at the "=" icon in the equation you are trying to encounter. "=" Sign, must be highlighted.
If not, you must tap the "=" icon and press the [ENTER] key to highlight it.
Display window must be set to the correct size and location
If viewing the window is set to the wrong size or location, the calculator can be lied but you will not see it screen.
There are many ways to adjust the viewing window, but the easy reliable method is simply "Zoom Out" until you see the action you are 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 are trying to view. Now you should have some idea of which window you need to use to see the operation written. Press the [WINDOW] key at the top of the calculator and set the display properties as needed.
