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.

I need step by step instructions on how to work the TI-83 Plus


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.

How do i solve matrix equations on my calculator


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.

Solve a matrix of complex numbers using ti89 or any other ti calculator


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!

What does error #13 dimension mean on my TI-86 calculator, please.


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.

When i attempt to differentiate an equation, the answer is a matrix, how can i get it back to normal, and get the actual answer?


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.

How do i solve a matric problem with a TI- 83+


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.

How do i use my ti 84 plus to solve problems with the gauss jordan method, to obtain the cofactors of a matrix, and many oder operations with matrices


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.
