Question about Casio FX9750GII Graphic Calculator
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

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:
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)

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].
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]
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.
