I had the same problem... all you have to do is reset the calculator:

Type:
2ndF
ALPHA
It'll give you a choice Mem (0) or Reset (1)... press 1
Then it'll say Reset? (0)... press 0

And your calculator should be as good as new!

SOURCE: I can not find the arc key or the INV 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.

Staples scientific calculator BD-107i


To find percentages on this calculator, or any calculator, you divide one number by the other, and multiply the result by 100.

For example, for 2 out of 5, we type in 2, hit the divide button, type in 5 and hit the equals sign and we will get 0.4. To make this into percentage, we then multiply the answer by 100 to get 40%.

Good luck,

Paul

How to calculate inv logs on casio fx-82 au plus?


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.

My calculator is to light and i have no 2nd key


The key is marked [Shift] on Casios, [2nd] on TI's, and [2nd F] on Sharps. I have seen some cheap calculators that mark the key as [Inv]. HP calculators are rather different in that respect.

Inverse log function


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.

Where is the shift button


The SHIFT key is called [2nd] on certain calculators and [SHIFT] on others and [2nd F] on Sharps. On some clones it may be [INV]. On TI calculators it is [2nd].

My casio s/c fx83ES does not have an INV button. Can you help me


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].

How do i find inv for sin,i have tried the mode Deg 1 but i keep getting the wrong answer. can you help? Eg 0.6339869 INV cos ans should be 50.655113.


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.
