### How to find the polynomial roots in TI-83 Plus

One way is to use the Polynomial Root Finder and Simultaneous Equation Solver app.

Press the APPS key, then select PlySmlt2 and press ENTER. Press ENTER to get past the opening screen, then select "POLY ROOT FINDER" and press ENTER. Select the order of the polynomial and other settings as desired. Press F5 (the GRAPH key) to go to the next screen. Enter the polynomial coefficients, then press F5 to solve. The next screen will show you the roots (unless you selected real roots and the polynomial doesn't have any real roots).

If you don't have the app installed, you can download it from

### Err:no sign chng

If you were trying to find the roots (zeros) of an algebraic equation with the solve( command or the interactive solver you might have supplied an interval where the function is always positive or always negative. If the expression is always of the same sign on an interval, the interval does not contain a root.
• If you extend the interval, the procedure may not converge fast enough and the calculator may not find the solution.
• Abetter way to do it is to sketch the graph of the function and use the graph to choose a reasonable interval that extends on both sides of the root, and a better initial guess.
If you were doing some financial calculations,
• You attempted to calculate the I% variable when FV, N*PMT, and PV are all positive, or all negative.
• You tried to calculate Irr( when neither CFlist, nor CFO is positive
• You tried to calculate Irr( when neither CFlist, nor CFO is negative

### Whenever i try to link my calculator with other ones it always says error in xmit. no matter what i do

Hello,
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.
• 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 ti-cares@ti.com.

### The calculator is only graphing a half circle when it should be a full circle, specifically not in the negative y-values of the plane.

A circle is not a function and cannot be graphed in the regular y=screen. You can graph a circle in parametric mode.

To graph a circle in the regular y= screen, you have to graph it in 2 lines on the y= screen. I assume you've solved for y and gotten a square root equation. Remember a square root can be positive or negative. In line 1 of y= screen graph what you've been graphing and then graph the same equation in line 2 but with a negative in front of the equation. You'll get something that looks like an oval since the calculator screen is rectanglular. To make it look more circular (both parts aren't going to connect), press zoom and then select #5 (square).

### Graphing calculator help

The cord that comes with the TI-83 Plus is a unit-to-unit link cable. It allows you to share data from one TI-83 (or other compatible TI calculator) to another. If you have the optional TI-GRAPH LINK adapter cable and the appropriate software it can also be connected to a PC.

For more info, here is the link to the manual. Chapter 19 discusses it in great detail.

Hope this helps..and good luck!
