Question about Casio FX9750GII Graphic Calculator

Sigma notation on fx9750gii

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

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)
Goodluck!

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.

SOURCE: standard deviation

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)

SOURCE: how to sum series

Click on the Mode button twice until you see “SD”. Select 1. This puts the calculator in Statistics Mode. Enter the first number, 1.
Hit the M+. (n= 1 will appear in the window)
Enter the second number, 1.
Hit the M+ key. (n=2 will appear in the window)
. . . . .
Enter the last number, 7.
Hit the M+ key. (n=7 will appear in the window)
Hit shift, 2. (This invokes the S-Var option.)
Hit 1 for the sample mean. Hit Enter.
Hit 3 for the sample standard deviation that we will use in class. Hit Enter. here you can also ffind the sum of all numbers

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 [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.

How to solve the inverse of a 3x3 matrix

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.

I am using a casio fx 9860 .... i dont know how to change the mode to linear it and how to do log when the base is not 10 .... like log 2

In Run screen press [SHIFT][MODE] to enter SetUp.
Look for the line Input Mode (it is the 1st on the SD version). Highlight the line then press the TAB at the bottom of screen that says Lin (F2 key). Press EXE when you finish with SetUp.

To use the logab( function,
1. open the Run/Mat screen.
2.Press the OPTN key.
3.Press [F4:Calc].
4. Press [F6:].
5. Press [F4:logab]

the command is displayed on the screen,.
6. Enter the base then the argument).
7. Close parenthesis if you want and
8. press EXE.
Example logab(2,8) =3
