I would like to have instructions on the use of my TI-86 graphing calulator

Read on how to set up calculator for graphing. And check your input.

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

I have a TI-83 and there has been a dark spot on my screen for several years and it has not been a problem. Try to use yours for as long as possible unless the screen is unviewable.

Press the [2nd] key and then, press and hold [up arrow] key. Keep repeating the process until desired darkness.

From the manual:

You entered an argument with an inappropriate dimension.
You entered a matrix or vector dimension less than 1 or greater than 255 or a non-integer.
You attempted to invert a matrix that is not a square matrix.

If you can't figure it out from here, please reply to this post telling us what you were graphing or attempting to graph when you got this error.

To restore memory on a TI 84 to factory settings follow the directions on pages 108 and 109 of the instructions manual (TI 84 Plus Silver). Otherwise look in the index for RESET MEMORY to get the right page. Be sure you read the precaustions!!!!!!

Hello,
Read the following answer from the TI Knowledge Base.
Hope it helps.

How can I troubleshoot an Error in Xmit error message when transferring data between two graphing calculators?

The Error in Xmit error message is returned when a connection cannot be established between two calculators when attempting to transfer data. There are several factors that can contribute to this error message.
• The calculators being connected are not compatible for data transfer.
• The data cable is not firmly connected to both units.
• The receiving calculator is not in receive mode.
• The I/O port on one of the graphing calculators is damaged.
The procedure for connecting two graphing calculators is as follows:

• Connect the data cable to the I/O port of each unit. The cable will fit tightly in the I/O port and snap into place. If silver from the cable is visible, the cable is not properly connected.
• Access the Link menu on each unit
• Place the receiving graphing calculator on "Receive"
• Place the sending unit on "Transmit" or "Send" from the Link menu.

Once the data has been selected, the transfer will commence accordingly.

The data transfer protocols for graphing calculator is as follows:

• TI-73 - Link allows data sharing with another TI-73, TI-82, TI-83, and TI-83 Plus.
• TI-82 - Link allows data sharing with another TI-82.
• TI-83 - Link allows data sharing with the TI-82, TI-83 family calculator, and TI-84 Plus family calculator.
• TI-83 Plus/TI-84 Plus family- Link allows data sharing with another TI-82, TI-83 family calculator, and TI-84 Plus family calculator.
• TI-85 - Link allows data sharing with another TI-85(To a TI-86. Not From a TI-86).
• TI-86 - Link allows data sharing with another TI-86 and from a TI-85 to a TI-86.
• TI-89 family- Link allows data sharing with another TI-89 family calculator and from a TI-92 family calculator.
• TI-92 family- Link allows data sharing with another TI-92 family calculator and from a TI-89 family calculator.
• Voyage™ 200 - Link allows data sharing with another Voyage 200 and TI-92 family calculator.



If the cable does not fit properly into the I/O port, or if the I/O port appears to be damaged (broken or separated plastic, obstruction inside the port), call 1-800-TI-CARES (1-800-842-2737) M-TH 8:00 AM - 7:00 PM FRI 10:00 AM - 7:00 PM Central Standard Time to speak to a representative or sending an email to [email protected].

Hello,
Here it is
[Diamond][Y=] enter y1=(2-X)^(1/3)
[Diamond][GRAPH]



Hope you liked the graph

Hello,
Use the stat menu. Enter 1st member of a pair in List1, Enter 2nd member of pair in List2. Graph the data as a scatter plot in stats plots.
Hope it helps.

Most likely you're trying to graph a function while you have the stat plot turned on. Turn off the stat plot and try it again.
