The INV button is replaced by the SHIFT button, which gives access to the functions in yellow/orange text above the buttons.

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.

Of course. Just press the INV key before pressing the appropriate trig function key. For example, to calculate the inverse sine, press INV then sin.

Set your calculator to the **DEG**ree mode. Then **2nd** and **tan** buttons.

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].

inverse button is used for 2 things

for trig sine inverse for example use 2nd sine

for x inverse use the 4th button down on the far left

for trig sine inverse for example use 2nd sine

for x inverse use the 4th button down on the far left

You didn't specify what calculator you have.

On my TI30XA, 0.6339869 '2nd' 'COS-1' gives 50.655114

On my Windows XP calculator, 0.6339869 'Inv' 'cos' gives 50.655114

On a Casio FX-300ES, 0.6339869 'Shift' 'cos-1'

I hope one of these helps. If not, let me know what calculator you have and I'll figure it out.

Try the 2ND key instead of INV.

There is an inverse button below the math button, but if you hit second and the tan it should give you the inverse of tan. Hope this is what you wanted

I can find "inv" on my calculator to do triganomerty questions
