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.

I am sorry but the image does not show any Degree button.

To set the angle unit you have to press the Mode button twice before you arrive at the angle unit configuration. See the screen capture below.

Look for a key marked [x^-1] or [1/x]. The marking may be on the key or on the face of the calculator. In the latter case you will have to press the SHIFT key first. Before you can calculate the reciprocal of a number the number must be entered.

To convert from Polar to Rectangular

PRESS [SHIFT and -Rec] then enter the coordinate and angle

e.g. [SHIFT and -Recl]

Rec(15,0)=

r=15

0=0

The DEG is merely indicating that the angular mode is set to degrees. If you want to change it to radians or grads, press SHIFT MODE and make your selection.

Likewise, the FIX is merely indicating that the calculator is displaying numbers in fixed decimal notation. If you're not seeing any digits to the right of the decimal point, then you're in FIX 0 mode. To change it, press SHIFT MODE. You can choose FIX and the calculator will prompt for the number of digits, or you can select NORM.

Hello,

Press [MODE] and select [1:COMP]

Press [SHIFT][MODE] and select [3:Deg]. You can also use rad if the angle you are given is in radians.

To start the conversion

Press [SHIFT][-] (Rec) screen displays**Rec(**

Key in the radius r , ex: 3 screen displays**Rec(3**

Press [SHIFT][)] (,) to enter comma separator **Rec(3,**

Key in the angle in degrees, ex: 57.3; screen displays **Rec(3,57.3**

Press ) to close parentheses; screen displays **Rec(3, 57.3)**

Press [=]

Screen displays

**Rec(3, 57.3)**

**X=1.620720961**

Y=2.524532346

X and Y are the values of the coordinates. ** **

If angle is in radians, [SHIFT] [MODE][4:Rad] the command

Rec(3, Pi) gives X=-3, Y=0

I just realized that your question pertains to the FX82MS but is listed under the FX115ES (That is quite a difference) So my answer above does not concern you but I will leave it as is should anyone need the answer for the FX115ES.

Use the Rec function (shift of the - key).

Rec(r,t) converts a polar value of magnitude r and angle t in the current angular mode. The real value is assigned to X and the imaginary value is assigned to Y.

Use the Pol function (shift of the + key) for the reverse.

It's on page E-37 of the manual. If you've misplaced your manual, you can download a new one from http://www.casio.com/support/manuals
