Error domain message

This means that you're invoking some function with an argument out of the function's domain. For example, the arcsine function requires an argument between -1 and +1, inclusive. If you try to take the arcsine of 2, you'll get this error.

If you require further assistance, please reply to this post and specify exactly what you're trying to do when you get this error.

I keep on getting domain error when calculating inverse normal with aera: .025 mean: 1 and standard deviation: 0 on my TI 89

This is to be expected. A standard deviation of 0 means that all the data points are identical. Asking for the point below which .025 of the data lie is meaningless.

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.

2nd vars 2 (normalcdf( -999999,-.1923) Just trying to get area from z value -.0.1923 keep getting errors

The normalcdf function takes three arguments: the z value, the mean, and the standard deviation. In the "standard" case the mean is 0 and the standard deviation is 1. Thus, try calculating
normalcdf(-.1923, 0, 1) .

I'm trying to do sin-1 7/2 but it keeps saying math error.

That is correct: there is an error in your request. The range of the sine function spans the closed interval [-1, 1]. Thus the domain of the inverse sine function (the arc-sine) is the interval [-1,1]. However you are asking the calculator to calculate outside of the domain (7/2=3.5). If you are using the hyperbolic sine sinh, that is another matter.

Stat list keeps showing domain error ti 89

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.

Can't take inverse of sin

The inverse sine is only defined for values in the range [-1..+1]. Arguments outside this range will produce domain errors.

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?
