Question about Casio FX-115ES Scientific Calculator

Hello,

i would like to know whether this model casio FX-115ES can solve 5 by 5 matrices and if not please suggest me which can solve it.

According to the manual for the Casio FX115ES, the largest matrix it solves is a 3x3.

The Casio FX-570MS does not handle matrices. So you cannot create matrices, let alone invert them. Sorry.

The Casio FX115 ES handles matrices for up to 3X3 dimension. Create the matrix.Have its name displayed on the command line and press the [x^-1] (reciprocal ) key.

The calculator barely handles matrices of up to 3X3. Matrices with complex coefficients are well beyond its capabilities.

The enclosed screen capture shows all the possible dimensions for matrices on the Casio FX-991ES. As you can see the maximum dimension of any matrix is 3. You can only create matrices with dimensions less than or equal to 3.

If you want to manipulate 6x6 matrices, you can use one of the CASIO Graphing calculators, such as theCFX-9850GPlus, or the FX-9750G plus.

Graphing calculators from other manufacturers can also handle such matrices. The FX-115ES can handle matrices with dimensions up to 3x3.

Press MODE 6 to get into matrix mode. Note: do this only once. If you do it again, it will erase all your matrices. Pick the matrix, set its dimension, then the calculator will put up a screen allowing you to enter/edit the matrix elements. At any time you're in matrix mode, press SHIFT 4 to bring up the matrix menu.

Calculator should be in [MATRIX] MODE

Try the matrices 2X2 matrices matA [1,2,3,4] matB [5,6,7,8], Add them, subtract them, multiply them, take the square of each. If that works for these matrices, then it must be your data. Be careful with negative numbers. To enter those, you must use the change sign (-).

There is also the possibility that the instructions were misread.

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

First you must set Matrix calculation

[MODE][6:Matrix]. Then By entering one of the numbers [1:MatA] or [2:Matb] or [3:MatC] you get to choose the dimensions of the matrix

(mxn]. Once finished entering the matrix you clear the screen.

The operations on matrices are available by pressing [Shift][Matrix]

[1:Dim] to change the dimension of a matrix (in fact redefining the matrix)

[2:Data] enter values in a matrix

[3:MatA] access Matrix A

[4:Matb] access Matrix B

[5:MatC] access matrix C

[6:MatAns] access the Answer Matrix (the last matrix calculated)

[7:det] Calculate the determinant of a matrix already defined

[8:Trn] The transpose of a matrix already defined

To add matrices MatA+MatB

To subtract MatA-MatB

To multiply MatAxMatB

To raise a matrixe to a power 2 [x2], cube [x3]

To obtain inverse of MatA already defined MatA[x-1] [x-1] is the x to the power -1 key

Dimensions of matrices involved in operations must match (see you textbook for the rules)

Read the appendix to your user manual, there are several exemples.

Hope helps
