The inverse of log functions are power functions.
Inv of ln is exponential (e^x)
Inv of log in base 10 is 10^(x)
A function and its inverse usually share the same physical key. One function is accessed directly, the other by using the SHIFT or 2ndF key.

A function and its inverse usually share the same physical key. One function is accessed directly, the other by using the SHIFT or 2ndF key.
For the common antilog, use the 10^x function available as the shifted function of the log key. For example, to calculate the common antilog of 2, press SHIFT log 2 =
If you want the natural (base-e) antilog, use e^x available as the shifted function of the ln key.
To get the inverse trigonometric functions press the 2nd key then the trig function key. If you'll look at the key legends above the SIN, COS, and TAN keys you'll see the standard math notations for their inverse function.
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.
I depends on what you mean by INV. On some Chinese (AUREX, Staples) calculators the second function key is marked as INV. If that is the key you have in mind, on Casios it is the [SHIFT] key. On Sharps it is marked as [2ndF]
If you have in mind the multiplicative inverse (the reciprocal) then your calculator has such a key and it is marked [x^-1]. It the key represented on the following table at the intersection of the 2nd column and the 9th line (RECIPROCAL)
If you are thinking about the inverse of functions, then know that each function shares the same physical key as its inverse. For example to access the arcsine (the function inverse of sine) you press the [SHIFT] key before [SIN]. On the calculator you will notice that near the [SIN] key and to its left there is [SIN^-1].
