Question about Texas Instruments TI-83 Plus Calculator

At first you have to slving this equations in explicit form** y=f(x)** and the graphing it. See captured images

Posted on Mar 03, 2012

Isolate the y variable in each equation and enter the result (what y equals) into y1= and y2=. or use matrices. repost if you want to learn how to do that. it doesn't involve graphing, sorry.

SOURCE: graphing

The first solution will allow you to watch your
calculator graph two equations simultaneously rather than finishing one
before graphing the next; it won't solve the problem of having the
calculator unselect one equation when you select a second. To fix
that problem, try the following:

In order to select additional graphs, the Transformation Graphing App
will need to be uninstalled from the TI-83 Plus Family and TI-84 Plus
Family. Uninstalling the App does not erase it from the calculator, it
disables it from interfering with the normal graphing modes. Below are
the steps to successfully uninstall the App.

- Press [APPS] key
- Select Transfrm from the menu
- Press 1:Uninstall

SOURCE: My calculator will only graph one graph at a time.

This is simple... Back up all RAM, (press second+, then 2, then 1, press enter to back up something if backed up it will have a star by it) Then clear your RAM (pull out your batteries while the calc is still on or press second+, then 7, then 1)

Hope this helps!

SOURCE: Graph feature is not working on TI-83

you have one of your stat plots on that is what is messing it up. So either turn off the stat plots. Or just reset your calculator. hit 2nd then the plus (+) key then 7 then 1 then 2. Good luck

Add a graph .

In Documents Toolbox, select 3: Graph/Entry Edit

Unfold the menu and select Equation (not function). Enter your equation.

For the 3D part, I am afraid you will have to read the manual.

Error 07 Syntax

Means you made a typing error while entering the equation. Using the minus sign instead of the negation sign (change sign) (-), can produce a syntax error. Maybe you need to explicitly type the multiplication sign

y= (-) 1.5*x +3

Try entering it as 3 - 1.5*x

You must deactivate the Statistical plots.

Press [STAT].

In list that is displayed delect [4:PlotsOff] and press [ENTER]

Go to [Y=] editor to enter functions or press [GRAPH] if functions already entered.

If the message appears when you try to graph functions deactivate the
statistical plots. To do so:

Press [2nd][Y=] to access (STAT PLOTs)

Select [4:PlotsOff] then [ENTER]

That should solve your problem. Post a comment to this thread if you still have trouble graphing.

If the message appears in another context, it sure would help knowing the context of the error.

Press the Y= key to invoke the Y= editor. Enter in your equation.

Press the WINDOW key to set the window parameters.

Press the GRAPH key to have the calculator graph the equation.

For more details and options, see the "Function Graphing" chapter in the Guidebook.

Hello,

**First thing to do before any new type of problem**

1. Turn StatPlots OFF : press [2nd][STATPLOT][4:PlotsOff] [ENTER]

**Second thing: Clear the statistical lists**

2. Press [2nd][0][PGRM] DownArrow to point to ClrAllLists.

3.Press [ENTER][ENTER]

**Third thing : Configure the graph type to be FUNCTION graph**

4. Press [MODE]. If FUNC (on fourth line) is highlighted. Press [Y=] and start entering the functions.

5. If FUNC is not highlighted, use Down arrow till 4th line, highlight FUNC and press [ENTER]. Press Press [Y=] and start entering the functions.

**Fourth thing: Enter function and select them for graphing**

1. As you start entering the function Y1=, notice that the = sign becomes highlighted. Press [ENTER] when Y1 is typed in. Make sure the = sign for Y1 remains highlighted as cursor moves to Y2=.

2. Keep entering the functions and verifying that their = signs remain highlighted as cursor moves to another equation.

3. When finished press [ENTER]

4. Look at the graph style for each function: it is a bit of line to the left of each Y. Here is a picture of all the 7 styles.

To set a graph style, highlight the style to the left of the Y, and press [ENTER]. Each time you press [ENTER] you see a new style, in the order shown on picture.

Avoid the style of Y6, it is bubble, and as such will burst and disappear once graph is finished. Avoid also the triangular ones (for Y3 and Y4) they will shade areas of the graph, and may hide other functions.

**Fifth thing: Graph Functions.**

1. You can press [GRAPH] to see your graphs.

2. If one curve is missing (and you have not set its style to be rhe bubble), it may be due to the Window dimensions.

**Sixth Thing: Set Window dimensions and Zoom.**

1. Press [ZOOM][6:ZStandard] to use standard window dimensions.

2. If curve still missing, Press [ZOOM][3:Zoom Out] to zoom out so that you may be able to see a bigger range for the functions.

3. If necessary press [WINDOW] and set the Xmin, Xmax, Ymin,Ymax to values of your own.

Dimensions must obey the conditions: Xmin < Xmax, and Ymin < Ymax.

Hope that helps.

1. Turn StatPlots OFF : press [2nd][STATPLOT][4:PlotsOff] [ENTER]

Hello,

Hope it helps.

- Once you enter an equation, the corresponding equal sign is
highlighted by default.
- Before you draw the 2 graphs, move the cursor
to Y3 or Y4 and verify that the = signs for Y1 and Y2 remain
highlighted.
- If one is not highlighted, move the cursor on it and press ENTER.
- If you still have problem, press [2nd][STATPLOTS][4: PlotsOff] [ENTER].
- Command
**PlotsOff**echoes on main screen. - Press [ENTER], screen displays
**Done.** **Restart the graphing procedure.**- If all else fails, just reset the RAM by pressing [2nd][MEM][7:Reset][1:All RAM][2:Reset], press [CLEAR] to clear the message.

Hope it helps.

You shouild make it a habit to clear the RAM every time you start a new type of problem.
