Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator

You must have dropped the calc at some point huh? Sounds like the LCD is broken. You can try resetting the MEM, but I doubt it'll work since these calcs don't have color displays and yours is showing a blue line. This leads me to believe that the LCD is broken. Live with it, have it repaired professionaly, or buy a new calc.

First you must use a graphing calculator.

Most graphing calculators graph functions, i.e. relations of the form y=f(x).

Some graphing calculators are able to graph equations (not necessarily functions). On one of these calculators your draw the vertical line x=-3, then you shade to the left of the point x=-3. That gives you the real line from infinity up to but not including x=-3.

Generally, people do not need calculators to find the solutions to inequalities in just one variable.

Turn calculator ON

If you see no icons, press Menu

Press 3 (Graph) draw your function. (more on that later).

If the first line of the display show Graph Func : Y= you should be able to draw your function.

If it says anything else, press F3 TYPE to select the graph type and select functional by pressing F1 key Y=.

After the graph type is set to Y=, type the second member of your function y= f(x) on the first line. Make sure the = sign after Y1= remains highlighted after you move cursor. Otherwise select the function by pressing F1:SEL. Press F6 Draw.

Be careful with trigonometric functions. If angle unit is radian, set window Zoom to standard. If angle unit is degree, you must open the Window utility and set Xmin=-190, Xmax = 190 to see at least a period.

Read the first part of the answer to deactivate the statistical plots. No need to read the rest if you know how to do graphs.

Prepare calculator to graph

Turn StatPlotsOff to avoid errors:

Press [2nd][STATPLOT][4:PlotsOff][ENTER].

Setup Graph type

Entering the functions to draw (assuming you want to draw y= functions)

Selecting the Graph Style (You may ignore this now, because it is unimportant for just one graph)

Drawing the Graphs

ZOOMING

You can also press [ZOOM] to adjust.

The selection 6:ZStandard sets the dimensions as on the screen Titled Window (above).

Prepare calculator to graph

Turn StatPlotsOff to avoid errors:

Press [2nd][STATPLOT][4:PlotsOff][ENTER].

Setup Graph type

- Press [MODE] key.
- In Mode set up screen, make set the angle unit (if you are drawing trigonometric functions)..
- Use the arrows to move cursor to 3rd line to highlight
degree or radian and press [ENTER]. The important thing is that you be
aware of the unit so that you do not get unexpected results.
- On same screen, verify that
**Func**is highlighted. If you are drawing PARametric plots, POLar plots or SEQuence plots, you highlight the relevant item in the list - If it is not, use arrow to highlight Func and press [ENTER] to validate.
- Do not worry if you do not have exactly the same screen
as in the screen picture (We may have different OS Versions)

Entering the functions to draw (assuming you want to draw y= functions)

- Press [Y=] to enter function editor.
- Type in a function
- Press [ENTER] at the end of each function.
- Before pressing [GRAPH], make sure that all the = signs that define the functions to be graphed are highlighted white on black. If one is not highlighted, use arrow to move cursor on the sign and press [ENTER].
- In the screen capture 4 functions are slated to be
drawn.

Selecting the Graph Style (You may ignore this now, because it is unimportant for just one graph)

- Select the graph style:
The small piece of line to the left of a Y that defines a function is
the style.
- Move cursor on it and press [ENTER] .
- Each [ENTER] (on same line) selects another style.
- On the next screen you have all the styles available on the calculator.
- Do not select the bubble on line 6: It is for
animations. It will not leave a trace at the end of the plot.

Drawing the Graphs

- Press [GRAPH] to see the graphs.
- If one of them is missing, verify that its = is still highlighted, then use the [WINDOW] to set the Window dimensions,
- Here are the dimensions of the standard window

ZOOMING

You can also press [ZOOM] to adjust.

The selection 6:ZStandard sets the dimensions as on the screen Titled Window (above).

If you just want to draw figures (not graphs) on the calculator you should use the [Draw] command.

Press [2nd] [PRGM] (DRAW)

Select [4:Vertical]

Command echoes on main screen as Vertical

Enter the x-value where you want the line drawn (ex: 2) and press ENTER

You will get a vertical line at x=2.

Press [2nd] [PRGM] (DRAW)

Select [4:Vertical]

Command echoes on main screen as Vertical

Enter the x-value where you want the line drawn (ex: 2) and press ENTER

You will get a vertical line at x=2.

A. This is due to a mathematical error such as

- dividing by 0,
- an illogical operation,
- calculations outside the range of a function,
- using the exponential function with the [^] key,
- logarithm of a negative number,
- calculating the factorial of numbers larger that 69,
- what have you.
- Check the expression of the function you are trying to graph.

- Use keys to highlight [GRAPH] and press [EXE].
- Make sure the screen that opens says Graph Func Y= at the top.
- On the Y1= line enter X (use the [X,theta,T] key under the [ALPHA] key.
- Press [F6:Draw].
- You should see a staright line passing through the origin (0,0).

Your calculator is currently configured to draw polar graphs. To recover the more common Y= graphs,

- Press [MODE]
- Use down arrow 3 times to get to the line FUNC PAR POL SEQ
- Use left arrow to highlight FUNC and press [ENTER]
- Press [2nd][QUIT] to exit the MODE screen.
- Restart your graphing.

Hello,

A previous problem on statistics has turned the statistical graphs ON and that interferes with the graphing of functions.

TurnOff the STATPLOTS by pressing [2nd][STAT PLOT][4:PlotsOFF]. Command echoes on the home screen. Press ENTER. I was going to add to reset all ram just in case.

Make sure you are drawing the right type of graph. To check that press [MODE], scroll down to 4th line to highlight Func and press ENTER, if you are drawing y=f(x) functions. The others are PARametric, POLar, SEQuence.

Hope it helps.

Hello,

Turn calculator [ON]. If you do not see the menu icons, press [MENU]. Use the arrow keys to highlight the [GRAPH] icon.

An entry screen appears where you enter the functions you want to graph.

On the first line you have Y1= . After the equal sign enter 2[x] [X, theta,T] + 1. When finished press [F6: Draw] Your graph appears on the screen. If you see the axes, but no graph, press [Shift][V-Window] and press [F3:Std] then [SHIFT][QUIT] will take you back to the screen where you enter the functions to draw. There press [F6:Draw].

Hope it helps.
