How to format what I input in order to find the sum of a sequence on this calculator. I'm on RUN-MAT mode and press OPTN - CALC - > - Sigma( but then don't know how to input the lower and upper limits.

The syntax is

Sigma ( function (n),index n, starting value of index n, ending value of index n, increment of n).

If you omit the increment of the index the calculator will assume it is equal to 1

SOURCE: unable to use the integration function

First you have to computational mode to [MODE][1:Comp]. Then press [SHIFT][MODE][1:MthIO].

Press the Integral, a template with the distinctive Integral (Snake) sign appears, with two small rectangles for the limits, a larger rectangle for the function, and dx.

The cursor will be blinking in the large level-line rectangle. Enter your function using the [ALPHA] [Letter] combinations to enter X,Y,A,B,C,or D, then use the Down Arrow to enter the lower limit, then the Up Arrow for the upper limits.

After you finish press the [=] to get the numerical result.

You cannot obtain primitives, just numerical values.

pulse F1(CALC), F1(1VAR) and it goes to 1-Variable Screen and shows the following:

x-(mean): 49.3333333

Sumx:296

Sumx^2:15066

xon:8.78761755

xon-1:9.62635271

n:6

I guess that you wanted the x- and xon

Also are available in RUN mode through VARS, F3(STAT), F1(X), F2(x-) and F5(xon)

Enter the last number, 7.

Hit the M+ key.
(n=7 will appear in the window)

Hit shift, 2. (This invokes the S-Var

Hit 1 for the sample mean. Hit Enter.

Hit 3 for the sample standard

SOURCE: When trying to find the determinant of a matrix

When you press the OPTN key you see Tabs at the bottom of the screen. The second one from the left should be the submenu for matrix operations.. When you press F2:MAT, the new tabs are Mat, M>L (Matrix to List), Det (command to calculate the determinant etc.

Here is a detailed account of how to calculate the determinant of a square matrix.

I assume you know how to define your matrix, but I will repeat it here for others who might not know. You can skip to **Calculation**

1.Turn Calculator ON. If there are no icons, press [MENU].

Data Entry

2.Use arrows to highlight [MAT] icon. Press [ENTER]

3.Highlight
the first line where it says Mat A. Use the right arrow to enter the
dimensions of Matrix A. Enter 3 and press [EXE]. The cursor moves to the
second dimension. Press 3 and press [ENTER].

4. The matrix entry screen appears.

5. Enter first matrix coefficient a_11 and press [ENTER]

6. Enter a_12 and [ENTER]

.....

Key in last coefficient a_33 and press [ENTER]**Calculation**

Press [MENU] and [RUN]

Press [OPTN][F2:MAT][F3:Det] Command echoes on screen as **det**

Press [F1:Mat] echoes on screen as Mat; screen shows **det Mat**

Press [ALPHA] A The screen displays **det Mat A**

Press [ENTER] to calculate the determinant.**If the matrix is not square, you cannot calculate its determinant.**

A. Define the matrix (Create it)

Turn calculator ON.

Press Menu,select the MAT icon and press [EXE]

You see a list of possible matrix labels (A, B, C,D,E,F)

All that have not been created have a "none" to their right

Highlight a matrix name and press the right arrow. Where there was "none" , you have a template 0x0.

That is where you specify the dimensions (mxn). exemple. 2x2

Enter the first dimension and press [EXE]

Enter the 2nd dimension and press [EXE]

A matrix template opens where you enter the coefficients left to right and up down.

After each coefficient press [EXE]. Cursor moves to the next coefficient, etc.

At the bottom of the screen you have 3 menus for Row and column manipulations. But those will have to wait for now.

Press [SHIFT][QUIT] to return to the list of matrices to create new ones

**B. Operations on matrices**

Once you have one matrix, you can do operations on it: Calculate the determinant (if matrix is square), calculate its inverse, transpose, augment it, fill it, etc..

These operations are accessed as follows.

Quit the matrix editor by pressing [Menu] and selecting the [Run] application.

Press [OPTN][F2:MAT]

You have the menus Mat,M(atrix)->L(ist), Det(erminant), Trn (transpose), Aug(ment) ->, Iden(tity),Dim(ension) Fill

Exemple : calculate the determinant of a matrix A (already defined).

You press the [OPTN][F2:MAT] key sequence (just above)

Press [F3:Det]; the command det is displayed on screen.

Press [F1:Mat] the identifier Mat is displayed.

Press [ALPHA] A; screen display det Mat A.

Press [EXE] to get the value of the determinant.

**C. Square of Matrix A**

[OPTN][F2:MAT] (MAT) [Alpha] A ^2 [EXE]

**D. Product of two compatible matrices MatAXMatB**

[OPTN][F2:MAT] (MAT) [Alpha] A [*] (MAT) [ALPHA] B [EXE]

**E. Calculate the inverse of a square matrix** (Mat A)

Use commands like the ones above to display the command**Mat A**, the press the [x^-1] key. You will get the inverse if matrix can be inverted.

If you have mastered matrix manipulations on the TI calculators, it should be a breeze to learn the same on the Casios.

- Turn calculator ON.
- Press Menu,select the MAT icon and press [EXE]
- You see a list of possible matrix labels (A, B, C,D,E,F)
- All that have not been created have a "none" to their right
- Highlight a matrix name and press the right arrow. Where there was "none" , you have a template 0x0.
- That is where you specify the dimensions (mxn). exemple. 2x2
- Enter the first dimension and press [EXE]
- Enter the 2nd dimension and press [EXE]
- A matrix template opens where you enter the coefficients left to right and up down.
- After each coefficient press [EXE]. Cursor moves to the next coefficient, etc.

Press [SHIFT][QUIT] to return to the list of matrices to create new ones

Once you have one matrix, you can do operations on it: Calculate the determinant (if matrix is square), calculate its inverse, transpose, augment it, fill it, etc..

- These operations are accessed as follows.
- Quit the matrix editor by pressing [Menu] and selecting the [Run] application.
- Press [OPTN][F2:MAT]

- You press the [OPTN][F2:MAT] key sequence (just above)
- Press [F3:Det]; the command
**det**is displayed on screen. - Press [F1:Mat] the identifier
**Mat**is displayed. - Press [ALPHA] A; screen display
**det Mat A**. - Press [EXE] to get the value of the determinant.

[OPTN][F2:MAT] (MAT) [Alpha] A ^2 [EXE]

Product of two compatible matrices MatAXMatB

[OPTN][F2:MAT] (MAT) [Alpha] A [* ) (MAT) [ALPHA] B [EXE]
