SOURCE: Casio fx-9860g ............ how to do percent operation

Hello,
[OPTN][LIST] scroll right till you find %. Press the function first then the number. It gives you the percent.
Hope it helps.

Hello,
I suggest you reset the calculator by removing the main batteries. This will free up space to solve the problem.
Hope it helps.

SOURCE: Casio fx-9860G graphics calculater, vertical line segment

I am not sure how you can create such function (the range limitation do not work for x=c) but you can draw a vertical segment, just do not call it a function.

Draw a graph Y1=0
Then press SKETCH function key and use the F6 key to cycle through the TABS at the bottom of the screen. Look for the TAB named PEN. and click the function key below it.

Use the arrows to move the cursor to a spot on the screen (near the bottom), Press EXE to fix the starting point of the segment. Then use the Up arrow to draw a vertical segment from bottom to top.

SOURCE: how do you find out

The following screen captures are from another Casio Graphing calculator so the menu screen may not look yours. However the instructions are identical.

Here is a sequence of screen captures to illustrate how to do it.
Turn calculator ON. Use arrow to highlight STAT and press EXE



Press F5 DIST


Then select F3 CHI


Choose Cpd or Ccd


If you choose Cpd : you must enter the Chi value you want, and press EXE, then the number of degrees of freedom (df) and press EXE. The Execute command is highlighted. This allows you to perform the actions
indicated by the Thumbnails at the bottom of the screen: calculate a value or Draw the distribution.






In the example above I took Chi=1, and df=3 and pressed the CALC menu.

If I press the DRAW menu instead, the distribution is displayed.


If you want the other distribution Ccd, press Ccd instead in screen capture 4.

Here is enough to get you started and a little more.
Read the post ant consult your calculator manual. The screen captures below may not look exactly as your calculator but the steps are identical.

A. Define a matrix (Create it)

1. Turn calculator ON.
   
2. Press Menu,select the MAT icon and press [EXE]
3. You see a list of possible matrix labels (A, B, C,D,E,F)
4. All that have not been created have a "none" to their right
5. Highlight a matrix name and press the right arrow. Where there was "none" , you have a template 0x0.
6. That is where you specify the dimensions (mxn). example. 2x2
7. Enter the first dimension and press [EXE]
8. Enter the 2nd dimension and press [EXE]
9. A matrix template opens where you enter the coefficients left to right and up down.
10. 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..

1. These operations are accessed as follows.
2. Quit the matrix editor by pressing [Menu] and selecting the [Run] application.
   
3. Press [OPTN][F2:MAT]
4. You have the menus Mat,M(atrix)->L(ist), Det(erminant), Trn (transpose), Aug(ment) ->, Iden(tity),Dim(ension) Fill

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

1. You press the [OPTN][F2:MAT] key sequence (just above)
2. Press [F3:Det]; the command det is displayed on screen.
3. Press [F1:Mat] the identifier Mat is displayed.
4. Press [ALPHA] A; screen display det Mat A.
5. 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]



Part E Invert a (square, non singular) matrix that was already defined.

Press [OPTN] [F2:Mat] to open a screen similar to the one in capture above
Press [F1:Mat] to have identifier Mat displayed.
Enter the name of the matrix by pressing [ALPHA] A, for example.
Press [SHIFT] [ ) ] activate the (x^-1) key.

This is what you might see (with parentheses and without).


Press [EXE] button to calculate the inverse.
