SOURCE: how do i calculate permutation in fx-82ms casio

Hello,

Find on the calculator the [nPr] key either (you may have to use the [2nd] or [2ndF] key) then

1. Enter the number that corresponds to n eg. 18

2. Press the [nPr] key

3. Enter the number that corresponds to r eg. 5

18[nPr]5 gives 1028160

If you calculate combinaitions use [nCr] key.

Hope it helps

SOURCE: how to calculate inverse of a 3x3 matrix in casio

Hello,

Here is the solution for th FX-991ES.

Hello,

The error may be due to the key you used to signifie
inverse. It says in the manual that you should use the key x^-1 not the
one used to input general powers.

Here is screen capture from the
Appendix to the manual. The picture shows the sequence of keys to press
to obtain the inverse of a 2x2 matrix. It is taken from page 41 of
Appendix

The matrix used in the exemple is

a_11=2 a_12=1 a_21=1 a_22=2

Here is the link to download the manual and the appendix

The link is for FX991ES. Look there foe you manual.

Hope it helps

SOURCE: Hi, I have a Casio calculator fx-991MS giving me wrong answers!

Hello,

I am only looking for a plausible cause of the error, because I do not believe your calculator can make such a mistake. I think you **accidentally activated the Exponential display format** and did not pay attention to the small, raised -03 that came at the end of the number displayed. It is a common mistake for those not very familiar with Scientific or exponential notation.

Let us try to reset your calculator to the normal (floating point) format.

Press the [MODE] key a number of times until you reach a screen that has FIX, SCI, NORM and under each one a number (FIX 1, SCI 2), Norm 3). To have the number of decimal place you gave in your result (4 decimal digits), you press 1 to select Fix then 4.

Be aware that scientific calculators usually stop displaying results in floating point format ( 0.0000045 ) if the number is smaller then 0.001. So basically, 0.00099 will be displayed as 9.90-04, -04 being raised above the level, and in smaller size.

Hope it helps.

Not all matrices are invertible. The matrice must be square.The matrix must be non-singular: Its determinant must be different from 0. Your error comes probably from the key you used to calculate the inverse. Use the reciprocal key, the one marked with x^-1. If the marking is not ON the key, use the SHIFT button prior to pressing the relevant key.

Yes. Simply enter the fraction and press =. If the calculator is in the MathIO mode it will display the fraction in its simplest form. If you're in the LineIO mode, press the S--D button to convert the decimal to fraction.

Yes. Pressing the DMS key (two keys above the 8 key) when a result is displayed toggles the result between decimal degrees and degrees-minutes-seconds.

For example, to convert 3.5 degrees, press 3 . 5 = and you'll see 3.5. Now press DMS and you'll see 3 degrees 30 minutes 0 seconds.

It's a bit convoluted, and it only works for integers, but here's one way. Press MODE 4 to switch to BASE-N (integer) mode. If the screen doesn't read "Dec" then press the x^2 key. Now, to calculate m mod n, calculate m-m/n*n. No shortcuts, no rearranging. That's m minus m divided by n times n. You have to enter both numbers twice, but you will get the modulus.

Press MODE 1 to return to your previously scheduled calculations.

Now, to calculate a mod b, calculate a-a/b*b. No shortcuts, no rearranging. That's a minus a divided by b times b. You have to enter both numbers twice, but you will get the modulus.

You need to be in complex mode before you can do any calculations involving complex numbers. Press MODE 2 to switch to CMPLX mode. When you're done, press MODE 1 to switch back to COMP mode. (Yes, the names are confusing. I didn't pick them.)
