I have a TI-84 Calculator and I can not find the INV key or the arc key.
The INV key that you may find on some scientific calculators has, on the TI 83/84/ Plus calculators, an equivalent key marked [2nd].
On the TI83/84 Plus, each trigonometric function has a second marking [SIN^-1], [COS^-1] or [TAN^-1]. To calculate the inverses of trigonometric functions ( arc sine, arc
cosine, arc tangent) you press [2nd] followed by the relevant
trigonometric function key For example, [2nd] [SIN] displays sin^-1( on the command line.
Unfortunately the hyperbolic functions and their inverses are only accessed through the CATALOG. You press [2nd][0] to open the CATALOG. Then you scroll down the CATALOG list to reach cosh(, cosh^-(, sinh(, sinh^-1(, tanh(, or tanh^-1(.
To speed the search in the catalog, you use the ALPHA keyboard: To reach cosh(, press[PRGM] and you scroll down from there.

We are accustomed to see that the inverse of "x" to be designated as a "1/x". If using Sharp EL 531WH the inverse function you will get when you press the yellow key "2ndF" and thereafter the "X^2" key. Good luck.
SOURCE: Can you Factor on a TI-84? IF not, does the TI-89?
Well, to answer part of your question, yes... the TI-89 does factor like this. it is inputted like this:
factor(6*x^2+11*x+4,x)
Check the catalog in the TI-84 (which is 2nd-zero) and look under F for factor()
SOURCE: comma key on TI-84 Plus Siver Edition calculator.
The comma key on the TI 84 SE is above the 7 key, and it is just left of (, right of x squared, and below SIN. thats where the "," key is. If you're asking something else, please clearify. My understanding is that you don't know where the comma key is.
SOURCE: My TI 84 will not turn on. All batteries have been
try adjusting the contrast up using 2nd + up
just keep pressing it and it should turn back
SOURCE: everytime i try to graph i get an error saying inv...
You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.
