The Greatest Integer Function (int)

Hi, I am trying to figure out if the TI-84 calculator is able to do "greatest integer fuction" problems on it. Whenever possible, I just wanted to know if you can help me in telling me how to find it in the calculator.

Thank-you so much =D

The greatest integer function (also called a step function) is actually a piecewise defined function with a special definition. The function has the notation f(x)=||x|| or f(x)=[[x]] when it is written, but the TI-83 and the TI-84 designate this function by using f(x)=int(x) and is found in the MATH NUM menu. This function is the greatest integer less than or equal to x. So, f(1)=1 and f(1.4)=1. Since this is a piece-wise function you should use DOT mode.

Hi,
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
goodluck!

You do the operation to get a decimal number.
Isolate the integer part (to the left of the decimal point)
Convert the non integer part (decimal part) into a fraction.
Write the result as (integer part) (fraction part)
3/2=1.5
Integer part is 1, decimal part is 0.5
0.5 as a fraction is 1/2

How to fix INVALID DIM in plotting graph

The ERR:INVALID DIM error message may occur
if you are trying to graph a function that does
not involve the stat plot features. The error can
be corrected by turning off the stat plots. To
turn the stat plots off, press y ,and
then select 4:PlotsOff.
• You specified a list dimension as something
other than an integer between 1 and 999.
• You specified a matrix dimension as something
other than an integer between 1 and 99.
• You attempted to invert a matrix that is not
square.

How do I work the poissonpdf fuction?

The poissonpdf function computes a probability at x for the discrete Poisson distribution with the specified mean u, which must be a real number >0. x can be an integer or a list of integers.

As an example, to compute the probability with mean 1.9 and x=4, press
2ND [DISTR] ALPHA [C]
enter 1.9 on the first line and press ENTER
enter 4 on the second line and press ENTER
press ENTER again.
This will paste poissonpdf(1.9,4) onto the command line. Press ENTER again to see the result (about 0.08).

I am trying to divide a power of 10 by and another number to a neg power of 10

For integer powers of 10 you can use the EE shortcut. [2nd][,] displays E.
For non-integer values of the exponent (such as -5.34) you must use the key sequence [2nd][LOG] (10^x) then enter your negative non-integer exponent.

How do you graph a greatest integer problem

To graph a greatest integer function, follow these steps:
1.) Press Y= 2.) Press MATH, then scroll to the right one column and select "int(" 3.) Enter your function inside of the parentheses, and make sure to put a closing parentheses at the end of the function you are inputting. 4.) After you have closed the parentheses to the "int(" command, add 1 to the end of the equation. This is because the "int(" command tells the calculator to take the lowest integer of the value inside of it. If you add one, then instead of .68 becoming 0, it becomes 1, and 1.724 becomes 2, etc.

How do i generate random integers with a ti 89 titanium?

Use the rand() function. If you give it a positive integer argument n, it will return a random integer in the range in the interval [1, n]. You'll find rand() in the MATH/PROBABILITY menu.

The random number generator function is called Ran# and can be accessed in RUN mode by pressing:
[OPTN] [F6] [F3] (PROB) [F4] to access the (Ran#) function
In the paragraph above, the bold text in square brackets indicates keypresses, while the text in parentheses represents the menus that appear at the bottom of the calculator screen. This also assumes there are no menus on the bottom of the screen when you begin. If PROB is already on the screen, then the [F6] key is not necessary, just press [F3] then [F4] at this point.

The Ran# function generates a random decimal number between 0 and 1. If you need to generate a number with a higher range, then there may be extra steps involved. For example, to choose a random number between 0 and 100, you would enter:
Ran#×100 or Ran#(100)

Let's say you want to simulate a dice roll, where you get an integer between 1 and 6. Your first step would be to do:
Ran#×6
This will give you a random decimal number between 0 and 6. But we need an integer, not a decimal. To make it an integer, you would change this to:
Int(Ran#×6)

Press [OPTN] [F6] [F4] (NUM) [F2] to access the (Int)

This now gives you an integer between 0 and 5. We just need to add 1 to the result.
Int(Ran#×6)+1
The result should be an integer between 1 and 6.

How do I get the Ti 85 to do random integers?

Functions on the calculator are bold. Numbers you choose are in italics.

For random positive integers between 0 and n use the following:

int (rand * n) + 1

int is on [Math] [Num] F4

and rand is on [Math] [Prob] F4

rand returns a random number x between 0 and 1 such that 0 < x < 1.

int returns the integer portion of a number such that int 123.456 returns 123 and int -123.456 returns -124.
