Casio FX9750GII Graphic Calculator - Page 3 - Answered Questions & Fixed issues
How do you solve for
Sorry, the calculator cannot solve such ualities (nothing to do with the absolute function).To find the solution set you need to study the two cases for the absolute value.
Case 1If x-1> 0, the absolute value is x-1. The inequality takes the form x-1<9. You can solve it as
x<10Case 2 If x-1<0, then the absolute value is 1-x. The inequality becomes 1-x<9. The solution for this inequality is x>-8Combine the two domains to find the intersection
-8<x<10
Sigma notation on fx9750gii
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
Finding max and min
After you create a graph, have the calculator draw it. To find the minimum or maximum press SHIFT F5 G-Solv. Use the appropriate tabs MAX, MIN.
How do i graph?
Press the Menu key. Use Arrows to reach Graph or press the digit key correspondin to it (maybe 4).In the Y= entry screen. Type in the function. Use the [X,Theta,n] key to enter X. When the expression is finished press EXE.Press the Function key F6 under the Draw Tab..
How do I get the
You cannot. The calculator does not have the Natural Display (math display) feature. I have heard that you can flash it with the OS of an FX-9860GII. At your own risk.
Modulus of function
To enter the MOD( function on the command line:
- Press Menu
- Press 1 or select icon Run>Mat.
- In Run>Mat screen, press the OPTN key.
- Press F6> to pan through the other options.
- Select F4:Num and press F6:> to get other tabs
- Press F4:MOD
Example: MOD(278,9)=8An alternative way is to use the Catalog.
- Press [Shift][4] (catalog)
- Press [ALPHA][7] to jump to letter M
- Scroll down from there to reach the MOD( command.
Common logs
Use the logab function in the MATH menu.For your example, press 3 . 1 4 [MATH] F2 3 . 1 4 EXE
How to garph cos^-1 x
- Select the GRAPH utility.
- In the screen that opens, make sure the graph type is set to function Y=.
- If not set to function, press F3:type and select it
- Highlight Function Y1=, and enter the function Y1=[SHIFT][COS][X,Theta, T] and press EXE.
- Press F6:Draw.
- Change Zoom or window dimension if necessary.
Make sure that the angle unit is set to radian:
- Go to Main RUN screen.
- Press SHIFT MODE to enter SetUp.
- Use down Arrow to move highlight to the ANGLE line.
- Press F2 to set angle unit to Radian.
You will have to play with the window dimensions or the Zoom .
How to put a calculator fx-9750GII in degrees
- Turn calculator ON.
- If you see no icons, press Menu then 1 to go to main calculator screen Run>Mat.
- In Run>Mat screen press SHIFT MODE to enter SetUp.
- Move the highlight to the line ANGLE. Press the F1 tab at the lower left of screen to select Degree.
- Press EXE to exit the SetUp screen.
(V=20hm^3)
Divide both sides by 20m^3 to get h = V/(20m^3).
How do i find the inverse of a 3x3 matrix on my
Create the Matrix in the Run/Mat screen
Press 1 to enter Run/Matrix screen
Press F1 >MAT. The next screen opens. Enter the dimensions (3x3)
In the template enter the coefficients. Press EXE after each item.
Press the AC button to exit thye matrix editor screen.Press SHIFT 2 to type the Mat identifier on the command line. Press the ALPHA key followed by A (if you are working with the A matrix.) At this point you have
Mat A on the command line.Press
SHIFT ) to get the x^-1 function. That is the one that calculates the inverse of a Matrix.
How do i find !
The symbol is used to represent the factorial function. That function appears in probability theory, so you will find it under the Prob menu.Turn Claculator ONIf you see no icons, press the MENU key.Press 1 to select Run/Matrix home screen.Press the OPTN keyPress F6> to move to the next page of TABS.The probability Menu is activated by pressing the F3 key.The factorial function is shown at the bottom of the screen as x!Enter the number whose factorial you want to calculate, and press F1.The calculator cannot calculate the factorial of numbers larger than 69.Note: If you have to calculate permutations and combinations, do not use the definition in terms of factorials. Rather, use nPr for permutations and nCr for combinations.
How do i type f(x)=-log(subscript 3) (x+2) to find
In run screen press OPTN F4:CALC, then F6:>, then F4:logab(.Complete the argument list by typing X+2, 3). Press EXE if you want to evaluate the expression. If the value of X has not been defined previously it is taken to be 0.
