Question about Texas Instruments TI-80 Calculator

Hi,

I do not have the calculator, so I checked the whole manual. There is no reference to matrices. So you cannot use use this calculator to solve matrix problems.

Sorry.

That should not prevent you from rating the solution.

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

Shift [x^-1] allows you to access the matrix features. Under Names you select the names you want to use for your matrices. Under Math you access the various commands. Under Edit you edit the contents of your matrices.

The calculator is a very advanced one. It has hundreds of commands, each doing something different. Do you honestly think that anybody, no matter how well intentioned, can possibly give you step by step instruction on how to operate the calculator? And for free.

TI publishes just such a guide book.**It is freely available on their website at education.ti.com.** Download the complete guide book, browse through it to look for the way to solve the problem you are studying. Be focused. Read only what you need, to solve the problem at hand.

However, if you have a more specific question such as how do add two numbers, how do I find the inverse of a matrix, or anything with limited scope, we will be happy to answer it.

Please formulate a question.

This calculator does not support matrix equations/operations. You can either purchase a more expensive calculator with matrix functions, or you can do it by hand. Here is a basic tutorial on matrices: http://www.miislita.com/information-retrieval-tutorial/matrix-tutorial-2-matrix-operations.html

The TI-83 Plus is a calculator which will do matrix manipulation and is easily found used on sites like eBay.

Well, the equation is Ax=b and we want so solve for x

There are several ways of entering the data, but this is one way

Code: A=[15+35i 29+1i; 46+13i 62+3i]

b=[0;0]

x=A\b which has the trivial solution x=[0;0] (the ";" means "next row", a space next column.) To input a matrix use APPs then Data/Matrix Editor then New. Then change Data to Matrix. Put in the name such as "AA" in the variable field. Then enter row and column dimensions. Then edit as a spread sheet. Use F6(util) to delete a column or row. To manipulate matrices, exit the matrix application, then go to MATH then Matrix. Notice that J(RowOpps) is available. Good luck and thank you for using FixYa! We would sure appreciate a 4 "thumbs-up" rating for this answer. Happy holidays!

Three possibilities:

1) You entered an argument with an inappropriate dimension.

2) You entered a matrix or vector dimension < 1 or > 255 or a noninteger.

3) You attempted to invert a matrix that is not a square matrix.

If you need further help, please specify the exact problem you're trying to solve.

I do cannot see how you can go from a scalar to a matrix. The only possibility is if your expression includes parameters , say A, B, or some such things that were previously defined as matrices.

If you had at some time defined a matrix (A or a) , have forgotten about it, and now you are using the symbol (A or a) as a parameter in a function you are trying to differentiate, the answer is bound to be a matrix.

I suggest you run the NewProb command, or in HOME folder, press [2nd][F1] (F6) [1:Clear a-z] [ENTER][ENTER]

I am no seer and I may have guessed wrong. If you still want to solve your problem, post a comment giving more information.

Hello,

You should try to use the correct heading.

Press [2nd][Matrix] right arrow to [EDIT][ENTER] to create the [A]

matrix. Exemple of a 3x3 Matrix [A].

Once the matrix [A] is created you press [2nd][MATRIX] -->[MATH]

You can add similar matrices, you can multiply matrices, subbtract them, raise a matrix to a power, extract the square root, etc...

Here are the other operations you can pefrorm on matrices. Sorry I cannot go into the detail of things;A minimun of theory is needed to be able to use the commands.

Hello,

The matrix Math tools, are accessed by pressing [2nd][MATRIX] ->>[MATH]. Scroll the list to find all row permutations, etc.

Sorry but you will have to implement your Gauss-Jordan method yourself, and interactively.

Hope it helps.

Hello,

The so-called (2x1) matrix is not a matrix. It is a vector.

Hope it helps.

use the simultaneous equation solver software available on ur ti-89 and enter the equation in the form of augmented matrix and you will get ur answer.
