# Domain Error on ti-84+

I am trying to program a game onto my calculator but it keeps giving me a domain error which I don't know how to fix.

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!

SOURCE: dec to hex conversion

Not sure if TI-89 mode keys are the same, but here's the solution for that calculator:
1. Hit the mode key
2. Hit F3 to get tot Exact/Approx (might be different for 89T).
3. Set it to Exact.
4. Take a look at T-89 manual pages 327, 328, 329.
Nice of TI to NOT include that in the manual, huh?

I had the same problem, this worked for me:

Mode -> page 2 -> Exact/Approx change from "Exact" -> "Auto"

I had this problem too, turns out that if any of your y-coordinates are 0 or negative you will get a domain error. Hope this helps.

Hello,
In Home folder, press [2nd][F1] (F6) [2:NewProb][ENTER][ENTER]. This will clear the calculator of old junk.
You get a domain error if for exemple a function takes integer arguments but you are feeding it decimals, or like the square root and ln which need positive arguments and you give them negative values.
Instead of looking at all the old junk (variables, functions, configuration settings in stat plots incompatible with your new plots) to find the offending ones, it is more efficient to clear the slate (NewProb) and start afresh.

Hope it helps.

An argument must be in a specified domain. For example, ans(100) is not valid because the argument for ans() must be in the range 1–99.

### What is wrong with my calculator? invNorm Error:Domain

DOMAIN ERROR:

- You specified an argument to a function or
instruction outside the valid range. This error is
not returned during graphing. The TI-84 Plus
allows for undefined values on a graph.

- You attempted a logarithmic or power
regression with a LX or an exponential or power
regression with a LY.

- You attempted to compute GPrn( or GInt( with
pmt2 < pmt1.

### What is ERR: Domain on thr TI 84 graphing calculator?

The arccosine function is defined for arguments in the range -1 to +1. -125.85/-120.36 is larger than 1 and hence outside the domain of the arccosine function.

Domain errror meaning that an argument must be in a specified domain.
It's not clearly what do you want to do but for three possible options solutions are on the captured images below(for radian mode).

### One of my values is being replaced with zero in the stat test options, causing a domain error. How do I fix this?

After looking in the manual, I read that
It takes as input the COUNT of successes in each sample (x1 and x2) and the COUNT of observations in each sample (n1 and n2). Thus your values of x1 and x2 must be integers (whole numbers).. Besides I duplicated your example taking x1=21, n1=43, x2=18, and n2=38 and I did not get the domain error.
I was able to draw the graph also.
You might want to check your values.

### How to find inv cos with ti-84 plus

Make sure the argument is between negative one and positive one, inclusive. The inverse cosine is defined only for arguments in that domain, anything else will give you a domain error.

### I get err:domain on my TI-84 plus when i do Sin -1 (60) why?

While the domain of the sine function is the whole of the real line, it range spans the interval [-1,1]. In other words the sine of an arbitrary angle is imperatively somewhere in the closed interval [-1,1].
So when you want to find the arc sine corresponding to a given value of a sine function, you cannot give as argument to the arc sine [sin^-1] a value that lies outside the interval [-1,1].

For your case, the argument is 60 and it is outside the permitted domain [-1,1]. That is why the calculator protests by signaling a domain error.

### Arcsine doesn't work?

Arcsine is only defined for arguments in the range [-1...+1]. If you supply an argument outside that range, you will get a domain error.
