How Do You Type This Into A Ti-84 Calculator

How do you type infinity into a TI-83 calculator?

Not possible. However, the largest number the TI-83 can handle is 9.9999999999...E99. For the most part, E99 is close enough to be considered for calculations with infinity.

How do I type small letters in my TI 84 Calculator?

Lowercase functionality isn't enabled by default; it is possible however.

This functionality can be activated using assembly programs written in hex code. So essentially, yes, you have to make a program (but you only need to really use it once).

The code to enable lowercase letters can be done as follows:
1) Create a new program ([Prgm] > New > 1:Create New... then name it).
2) Type the following EXACTLY into the program (don't include the colon):
:AsmPrgmFDCB24DEC9
The AsmPrgm token can be found in the Catalog, [2nd][0].
3) Exit, and reopen the Prgm menu. Go to the Catalog, and choose the Asm( token. It should appear on the home screen.
4) Go back to [Prgm] and find the program you just created. Select it. The home screen should now look something like "Asm(prgmLOWERC".
5) Hit [Enter] and a 'Done' message should appear. You should now be able to enter lowercase letters. Press [Alpha] twice to do this.

It is important that you type the hexadecimal characters EXACTLY as displayed; if you make one mistake, there's a possibility that your calculator will permanently crash, so be wary.

To disable lowercase, follow the same procedure as above, but use this code instead:
:AsmPrgmFDCB249EC9

As for typing something on the computer and transferring it to your calculator, you might be interested in something like Notefolio: http://education.ti.com/educationportal/...

Or, if you mean use something like a keyboard to type in your calculator, you can take a look at some drivers (still work-in-progress) that allow some basic functionality of this: http://usb8x.sourceforge.net/

How do you type in x bar on a ti-84 plus calculator?

[Vars] > 5:Statistics... > 2:x̄

How to type in fourth root in a ti-84 graphing calculator?

The easiest way to do this is this:

First type in 4 (since you want the fourth root; if you wanted the fifth root, you would first type in 5, and so on). Then press the "MATH" key (which is the key under the green "ALPHA" key). Then select the function that looks like this: x√ (yes, that's an x with a square root sign, though on the calculator the x is smaller).

Then type in the number you want to take the fourth root of.

So for example, if you wanted to take the fourth root of 16, this is how it should look like on your calculator:

4 x√ 16

And when you hit enter, you should get 2.

How do i find the arc function on a ti84 calculator?

"arcsin" is exactly the same thing as "inverse sin", which is the sin^(-1) button: use [2nd][sin]

"arccos is exactly the same as cos^-1: use [2nd][cos]

"arctan" is the same as tan^(-1): use [2nd][tan]

"arccot" is the same as cot^(-1); but there is no cot^(-1), so you have to convert it to inverse tangent.
for example:
arccot(1/2) means,
"What angle has a cotangent of 1/2?"
which is the same question as:
"What angle has a tangent of 2/1?" (because they are reciprocals)
In math talk, that's tan^(-1)(2/1); so,...
for arccot(1/2), type on calculator: [2nd][tan][2][enter]

For arcsec(3/2), type: [2nd][cos]2/3[enter]

For arccsc(5/4), type: [2nd][sin]4/5

How do I input a plus-minus sign (±) into my TI 84 calculator?

You can't, first solve the equation using + and record the answer, then change it into a - and solve again.

If you have say two or more ± signs, type in all combinations.
ex. ++,+-,-+,--
