Hello,
The TI 89 cannot calculate the inverse modulo, but you can enter a program that can do that. I found a link to such program. Here it is.

"Undefined" as answer to an inverse sine calculation


I suspect that you are confusing things a bit.
The inverse sine, called the arcsine is a function defined in the closed interval [-1,1]. And so is the inverse cosine. Any value outside this interval will give you a non-real result (meaning a complex one).
There are no limitations on the domain of definition of the inverse hyperbolic sine or sinh^-1
If your input value is allowed to be complex, the arcsine function gives a complex value. See the screen capture

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.

I need to know which button is the inverse button on my Ti-36X Pro please!


The inverse of what&? Each inverse function uses the same key (shifted) as its direct function. For the reciprocal key look for x^-1 or [1/X]

Hi, how do i calculate log^-1(-2) on my ti-30xa? thank u.


The inverse of the log function is the power function.
For log in base 10 that inverse is 10 to a power of
More generally, let b be the base of the logarithm. If y=log_b (x) then x=b^y
For your case log=log_10, to calculate the inverse you perform 10^(-2)=0.01=1/100
On calculators the log in base 10 and its inverse share the same physical key. One is accessed directly, the other is the shifted key function.

What button do you push on the TI-86 calculator to do the inv log function?


For the inverse natural log, press 2nd LN. For the inverse common log, press 2nd LOG.

For example, to calculate the inverse natural log of 2, press 2nd LN 2 ENTER and you'll get about 7.389 .

How do I calculate the inverse log on the TI-89?


Hello,
The wrong terminology is playing tricks on you.
  1. If you are talking about the natural logarithms, the inverse function of the natural log is the exponential: ln(e^(x))=e^(ln(x)) = x
  2. If you are talking about the common logarithms (log in base 10) to find the antilog of a number, say x, you raise 10 to the power of x.
Exemple: What is the antilog ( that is the name, not inverse log) of 0.345?
Answer; antilog of 0.345 = 10^(0.345) =2.21309471

Look at the last two commands on the screen capture.

ERR:SINGULAR MAT when finding inverse of matrices


If a matrix has a determinant of 0, this error appears. If you get this error, your matrix doesn't have an inverse.

"Err: Domain"


I think you may find arcsin(x) is equivalent in older nomenclature to sin^-1 (x)...ie use the "2nd" and the SIN key instead of typing arcsin.
eg. arcsin(0.5) is 30 degrees is the same as sin^-1(0.5)
The ^-1 does not mean reciprocal, but "the angle whose sin is." Here the minus one indicates a kind of inverse operation. The word arcsin indicates that same inverse.

How do i solve for x on my ti-89?


First to solve a problem, write it like this

solve(3/x-2+21/x^2-4=14/x+2,x)

Second, for inverse, do this (note the "y=" part)

solve(y=3x^2 -2x+1,x)

The calculator will rewrite the formula as x = ...
