20 Most Recent Texas Instruments TI-83 Plus Silver Edition Calculator - Page 2 Questions & Answers

It is possible that the backup battery is depleted and cannot keep the RAM refreshed when the calculator is turned off. I suggest you change the backup battery immediately.

Remove the batteries.
Press and hold the [ON] key for 10 seconds.
Put the batteries back in and try to turn it on.

No. Unfortunately, the TI-83 Plus Silver edition does not have the capability to factor variables.

You're probably trying to graph a function that does not involve stat plot features while the calculator is expecting them. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

I was having the same problem. Whenever I hit the graph button after a linear function was entered in Y1 I would get a screen that said "ERR: INVALID DIM 1:Quit"
I messed with a lot of settings but ended up returning settings back to default. The thing that fixed the calculator's ability to graph was UN-highlighting the Plot1, Plot2, and Plot3 words. If they are white on black they are highlighted. If the words are black then they are UN-highlighted.
To UN-highlight Plot1, Plot2, Plot3, do this: move the cursor up to the highlighted Plot1 and hit "enter." Notice the difference? Now do the same to the others and see if it fixes your problem like it fixed mine.
good luck.

Use the xth-root function accessible by pressing MATH 5. For example, to find the third root of 8, press 3 MATH 5 8 ENTER.

Water conducts and is a great enemy to a circuit board , more when the circuit is sensitive.
hence the last possible chance is to attempt the work according to the tips given in the link below.:

Use the TIconnect software to connect the calculator to a computer. Run the TIconnect software.

In the TIconnect main window click the button "TI Device Info". This will retieve the device info from the calculator. If this operation is successful, click the button "Udpdates." Then unselect all options in the subsequent popup window to leave only The OS




Follow instructions.

Part A or B will reset the memory. Part C answers your specific concerns. Please read the whole post before attempting the procedures described here.

The first diagnostics you should perform are:

1. Make sure batteries are good and inserted correctly, respecting the polarity diagram: Yes, I myself made this mistake and it must be ruled out before doing anything else.
2. After a change of batteries, the screen contrast can change: It may become too dark or too light. If it is too dark, you would not think about a malfunction because you see something on the scree. BUT it the screen is too light, it is easy to conclude that there is a malfunction because you do not see what the calculator is doing after you press a key.
   
3. So, the second measure is to adjust the contrast. Press [2nd] key and Release it. Then Press and HOLD the UpArrow until screen is dark enough.
4. A third easy measure is to use the TIConnect software (available on education.ti.com) to retrieve the device Info, and if calculator is recognized to reinstall or update the OS. You need a TI USB SilverLink cable.

Here are some more procedures to perform in the order they are presented. Please read the post till the end.

A

1. Remove one of the AAA batteries.
   
2. Press and hold the [CLEAR] key.
   
3. While holding [CLEAR], reinsert the AAA battery and then
   
4. turn the calculator on.
   
5. the calculator should display the message "RAM Cleared".
   
6. Release the [CLEAR] key and then press it one more time to remove the message "RAM Cleared".

B.

1. Remove batteries including the backup battery for 5minutes.
   
2. After the 5 minute period, reinsert all of the batteries and
   
3. turn the calculator on.
   
4. Adjust the contrast if necessary. (see above)
   

C.

This step requires the reinstallation of the system. So to use it you must download the TIConnect 1.6 software from education.ti.com. You must have the TI USB SilverLink or the TI Black serial cable ready.You must be connected to the Internet.

1. Remove one of the AAA batteries.
   
2. Press and hold the [DEL] key.
   
3. While holding [DEL], reinsert the AAA battery and then
   
4. turn the calculator on.
   
5. the calculator should display "Waiting...Please install calculator software now".
6. Connect the TI connectivity cable between the computer and the calculator.
7. Click on Start >> Programs >> TI Tools >> TI Connect >> TI OS Downloader.
8. Follow the on-screen directions to reinstall the calculator's OS.

If the message "Error! Press any key to turn unit off. Then turn unit back on." appears on the graphing calculator, quickly, remove one battery from the calculator and reinstall it while the transfer is taking place.

You have several ways to connect the calculator

• Serial Black cable that used to ship with the TI 83 Plus. It connects to a serial port on a computer and to the I/O port on the calculator. It requires the Graph Link software available on the TI web site (Downloads, Software and Apps, Connectivity)
• USB Silver Link cable. It connects a USB port on the computer to the the I/O port on the calculator. It requires the TI connectivity software, also available on the TI web site.
  
• An I/O cable to connect two calculators through their I/O ports.

This should help you setup your calculator to do graphing.

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).

TI calculators have an annoying habit of dimming the screen, especially when the batteries are changed, so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

Not the square root of any number. Both machines give the same result for the square root of 4, for example. The differences for other numbers are due to the fact that the two calculators use different processors and carry different numbers of significant digits for internal calculations. The square root of most numbers is an irrational number, with an infinite decimal representation. It has to be cut off somewhere. If you cut it off in two different places, you're going to get two different numbers (unless there happens to be zeroes where you cut...).

First make sure that the batteries are fresh and that they are inserted with their poles in the proper position. Secondly hit the "2nd" key and hold down up. This is the contrast adjuster which makes the screen images lighter or darker. I have seen many students complain about a broken calculator when it is just not adjusted properly.
Good Luck

If all you have done is to replace the batteries then only 3 causes are possible:
1 - when you removed the batteries a contact was damaged - you will have to open the calculator to check for that.
2 - the batteries aren't the correct type - you put rechargeables instead of alcalines.
3 - the batteries are either faulty or not installed correctly.

You can always restore lost or deleted statistical lists by pressing the STAT button. In the menu list that is displayed, press 5:SetupEditor and ENTER. The content of the deleted lists will however NOT BE RESTORED.

In the Y= editor (press the Y= button to get there if you're not already there), select the graph you want to shade. Press left-arrow to get the cursor to the far left (over what looks like a backslash "\"). Press ENTER to cycle through the graph styles. Your choices are Line, Thich, Above, Below, Path, Animate, and Dot.
