SOURCE: How can I solve a matrix on my Casio fx-9750GA

Hi,

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

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

- 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]

Hope it helps.

Thank you for using FixYa.

SOURCE: how to use casio fx-9750G PLUS to find inverse????

To calculate the reciprocal of a numerical value you can use

- 1 / numerical value or
- use the key sequence [SHIFT] [ ) ] (X to -1), if the number is already displayed (stored in answer Ans memory)

1 [/] 13 [EXE] result is 0.07692307692 or

13 [EXE] to have 13 in Ans memory (displayed) and [SHIFT][ ) ] [X to -1] [EXE].

For such a simple number as 13, calculating its reciprocal the second way seems ridiculous, but if the number is already displayed the second method is the only efficient one if you do not want to copy the result on a piece of paper and retype so as to calculate its reciprocal.

SOURCE: How to do inverse log on a casio fx 9750g plus

The inverse of a natural logarithm (ln) is the exponetial (e^x). Both share the same physical key [LN] pour ln and [SHIFT] [LN] (e^x) for the exponential.

Syntax is : [ln] 3 [EXE] gives 1.098612289

exponential of 4: [SHIFT][LN] 4 [=] 54.59815003

The inverse of decimmal logarith is raise 10 to a power. Both share tha same physical key [LOG]

log of 6 : [log] 6 [=] result is 0.7781512504

antilog of 0.77: [SHIFT][LOG] 0.77 [=] result is 5.888436554

For more complicated arguments (expressions) it may be a good idea to use parentheses to enclose the arguments of functions.

There is no button but a menu tab.

In
Run screen, enter the number whose factorial you want to calculate (
number can be at most equal to 69), press [OPTN][F6] to get to next page of menus.

For factorials

- Press then [F3](PROB) then [F1] (x!) followed by [EXE].

- Press then [F3](PROB) then[F3][nCr][EXE]

- Press then [F3](PROB) then[F2][nPr][EXE]

The fx-991ES does not do indefinite integrals.

For definite integrals, use the [integral] key just below and left of the big round cursor pad. For example, to calculate the definite integral of x^2 dx from 0 to 1, press [integral] [alpha] [X] [cursor-right] [0] [cursor-right] [1] [=]. After about a second you should see 1/3.

The Gamma function reduces to the factorial function if the argument is a positive integer. For this case see the screen capture.

For the true Gamma function with real argument, you might want to generate a table of values by using the general definition as an integral

where you can find other expressions you might want to play with.

The Casios FX-115 ES , FX-115 ES PLus, FX-991 ES, FX-991 ES Plus C can perfom numerical differentiation at a point, and numerical integration between two given limits.

*Press "SHIFT" then "MODE SETUP" find both of this on top next to your calculator screen.

*Once these are pressed, you should see a list of words on your screen: (1: MthI0 2: LineI0.... "The list goes on to".... 8: Ncrm)

*At this stage you should just press 3 and your calculator should be fine! :)

why cant they include infinity symbol ? sometimes i feel my calculator is so dumb !

The syntax for the evaluation of definite integrals (integrals with boundary limits) is as shown on the screen capture below.

$ (function , variable , lower bound, upper bound)

By default the name of the dummy variable is x. If you use another name, the variable must appear as an argument of the function, and as variable.

No. The calculator can compute definite integrals by numerical integration, but it does cannot do indefinite integrals.

Hello,

If by calculus problem you mean derivatives of functions, integrals, extrema and such things, I am sorry to inform you that neither the Casio FX-300MS, nor the FX-991MS can handle them. The newer Casio calculator FX-991ES is capable of performing numerical differentiations and integrations. There also graphing calculators by Casio FX-9750G, FX-9860G as well as by Texas Instruments (TI 83 PLUS/TI84PLUS) that are reasonably performant in that area.

Hope it helps.

Hello,

I assume that by anti-derivative you mean the integral. I believe that you can only calculate definite integrals with this calculator. A definite integral requires that you specify the function e.g ln(x), the variable, x, the numerical value of the lower limit, 0.5 and the numerical value of the upper limit , say 2.

Try this:**INT(sin(x),x, 0, pi/2)**

This calculator can only give numerical values of definite integrals. If you want to perform symbolic calculations, you shoul look towards some other, more sophisticated Casios Casio ClassPad 330, or the TI Voyage200PLT, or the TI89Titanium. etc.

Hope it helps
