SOURCE: how do i use the inverse log operation on the TI-84
The problem is simple. You're trying to get an [H+] concentration which is obviously going to have a value of some number times ten raised to a negative power. Therefore, you have to insert the negative value of the pH into the 10^(x). When you insert said negative number you will come out with the right answer.
i.e.
The pH of a sample of human blood was calculated to be 7.41. What is the [H+] concentration of the blood?
10^(-7.41) = [H+]
[H+] = 3.9 E-8
(the answer should only have two sig. figs because the pH has two digits after the decimal.
SOURCE: calculate inverse module
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.

Hope it helps.
SOURCE: I have a TI 84 plus silver ed. I am trying to find
Hello,
The inverse tangent or arctangent shares the ame key as tan. You access it by pressing [2nd][tan] number [)] [ENTER]. Be warned! The angle value displayed is the same as the one set in [MODE].
Hope it helps
SOURCE: Change TI 84 OS to TI 89 OS??
And why, pray tell, would you do such a thing? You will ruin your Ti84 Plus Silver Edition and will not have a working TI89. Besides, TI connect will refuse to transfer it.
If you like the capabilities of the TI89 Titanium, buy a cheap or used one on e-bay or amazon.com and spare your TI84PLus SE.
SOURCE: how do you graph y = the inverse contangent of x?
The cotangent function is not implemented on the TI84PLUS native OS and consequently you will not find its inverse function on the calculator. However, there exits an equivalence (definition) between arc cotangent(x) and arc tangent (1/x).
Thus cot^(-1)(X)= tan^(-1)(1/X),
Be careful. Since it is a multivariate function, some authors define the principal branch in the domain [0, PI], while others define the domain on [-Pi/2, Pi/2]. You will have to consult your textbook, or the documents you are using to find out the domain of the principal branch.
If you want to examine the matrix you want to inverse and, the one that is given you trouble pressing [2nd] [MATRX]. Then stroll and, select the one you want to look at by pressing, [ENTER]. You'll have to press, [ENTER] again and, matrix should display at the Home screen. At the Home when you get to them your looking for the ones that are not square, like 2 by2 or 4 by 4 etc. You might need to re-edit this matrix so, that it is square.
Your trying to invert a matrix that isn't square you might be using using the proper key sequence to create a inverse matrix. Here what the correct inverse matrix look on the Ti 84 Plus Home screen.
And pictured below is a Matrix is being inverted by using the ^ and the -1 keys. Which to inverse a Matrix on the Ti 84 Plus you have to use the [x^-1] key.
This is not the proper way to inverse a Matrix on the Ti 84 Plus. The proper way to inverse of a matrix, the [x-1] key must be used, instead of pressing the sequence [^][-][1]. The [x-1] key is the official inverse key and is located right under the Math key. It is also the same key that you use to get to the matrix menus. The [^][-][1] sequence is only raising the matrix to the -1 power and, will cause an error too. If you need any more help, just post a comment and, I'll respond quickly.
