How to calculate modulus of function using fx-9750GII ?

SOURCE: i do not know how

Hey it is. Okay, so start with a equation: say, y = -(1 |x|). Now type y = -(1 , then press the [OPTN] button, next to the shift. Next press the [NUM] button or F5. The first menu button should be Abs or absolute value. When your done it should look like this. y = -(1 Abs (x)) then graph it.

Hello,

The binomial probability distribution is defined as
P(r;p;n) =(nCr)(p^r)*(1-p)^(n-r)
where n is the number of trials, p the probability of success, and r the expected result.

Let n=20, r=7, p=0.15 ( I do not know wether this exemple has any meaning in the context of your problem, but you have to enter values that mean something to you. I am only showing you the key strokes

To enter 20C7 you press 20 [SHIFT][nCr]7 ;
To enter 0.15 to the power 7 you type 0.15[X to ] 7 the key is between
[x²] and [log]

To enter (1-0.15) to power 20-7, you type 0.85 [X to] 13
With [*] standing for multiplication key , and [X to] the raise to power key, the exemple above can be entered as

( 20 [SHIFT][nCr] 7) [*] ( 0.15 [X to] 7 ) [*] ( 0.85 [X to] 13 ) [=]

Here is a screen capture to show you what it looks like. However on this calculator the combination 20 [SHIFT][nCr] 7 is represented as nCr(20,7).



Hope it helps

I don't know about fx-9750gII, but for fx-991MS
Change the mode to REG
Then
Shift->3(DISTR)->1(P())->give your Z value

One not way would be to define a 4x4 matrix Mat A to hold the coefficients of the linear system. Then define a 4x1 column vector Mat V to hold the constants on the right.
Define a third 4x4 matrix Mat B you may leave filled with 0.
On command line, in Run Mat screen enter (Mat A) ^(-1) and store it in the zero-filled matrix Mat B. this is the inverse of Mat A.
If the inverse of Mat A exists, and it does in this case, the solution of the system is obtained as the column vector, resulting from the multiplication of Mat B by column vector Mat V

You can even shorten the procedure by just calculating ((Mat A)^-1)X (Mat V) [EXE]

To summarize

1. Create 4x4 Mat A and type in the coefficients of the linear system.
2. Create a 4x1 column vector Mat V for the right-hand sides
3. Obtain you solution vector as ((Mat A)^-1)X (Mat V) [EXE]

• use catalog or
• in RunMat screen, press [OPTN] followed by [F2:Mat], then [F1:Mat].
• At this point the identifier is on command line, and you have to press [ALPHA] [X,Theta, T] to enter letter A.
• You use a similar key sequence to enter Mat V

Actually, the answer is 79.

The fx-115ES does not have a key for the modulus operation. Nor does it have an integer-part or fractional-part operation. However, it is possible to calculate the remainder using integer arithmetic.

Press MODE 4 to shift into integer mode. Then type in 3 5 2 - 9 1 * ( 3 5 2 / 9 1 ) = and see the answer 79. It's a pain as both numbers have to be entered twice, but it does get the job done.

To get back to working with real numbers again, press MODE 1 ( or MODE 2 for complex).
