# I have a Ti-34-II calculator and i need to know how to use it for natural log but i dont see the function for it on here? is there even a way to?

When I try to do log functions on the calculator, I apparently don't know the correct way to enter data because I keep getting the wrong answers. And my prof says, "You need a different calculator." He couldn't figure it out either.

Just hit 2nd and the Pi key and you will get a list of Logarithmic functions. Tell me if this works.

### Antilog on ti-84

The common antilog is the shifted function of the common log key (marked LOG, just to the left of the 7 key). The natural antilog is the shifted function of the natural log key (marked LN, just to the left of the 4 key).

### Change base log

The TI 86 has two logarithmic functions: natural logarithm (ln) and common (decimal) logarithms (log). If you need the logarithm in any other base than e or 10 you need to use one of the two equivalent expressions
log_b(x) =ln(x)/ln(b) =log(x)/log(b)
Here b is the value of the base of the logarithm and x is the argument (the value whose logarithm you are seeking). Of course the argument x must be a positive number.
Note: On the TI 86 the log function can calculate the logarithm of a complex number, according to the manual.

### What button do you push on the TI-86 calculator to do the inv log function?

For the inverse natural log, press 2nd LN. For the inverse common log, press 2nd LOG.

For example, to calculate the inverse natural log of 2, press 2nd LN 2 ENTER and you'll get about 7.389 .

### TI BA 2 Plus Calculator: Cannot figure out how to use log(10) function, not the natural log but the base of 10 log

The BA II+ does not have a key for the common logarithm function. You can calculate the common log of a number by calculating its natural log and then dividing by the natural log of 10.

log10(x) = ln(x)/ln(10)

The same procedure works for logarithms to any base.

### How do i use the log function on my ba ii Calculator?

To calculate the natural logarithm of the value in the display, just press the LN button. If you need the common (base-10) logarithm, compute it as ln(x)/ln(10). That is, divide the natural logarithm of the value divided by the natural logarithm of ten.

### Where is the antilog button? I need to input antilog and i dont know how.

The common antilog is the 2ND function of the common log (LOG) key, just to the left of the 7 key. The natural antilog is the 2ND function of the natural log (LN) key, just to the left of the 4 key.

### Using the correct key combination to determine inverse log

Hi,
Sorry to contradict you but there are many types of logarithms, the most important ones are
2. the natural logarithms (logarithms in base e)
3. the binary logarithms (logarithms in base 2)
On calculators, the common logarithms are labeled [LOG], and the natural logarithms are labeled [LN].

The inverse function of the natural log function is the exponential (e^(x)), and the inverse of the log in base ten function is the function ten to the power of. It is called (sometimes) the antilog

Ex:
Question What is the antilog of 3.5678?
Answer The antilog of 3.5678 is 10^(3.5678) = 3696.579068
Verification: log(3696.57908) =3.5678

Hope it helps.

### Natural logarithm with TI-30XA calculator

I noticed that this calculator doesn't have a natural logarithm function as well. You can can always use the fact that
ln x = (log x) /log e or since log e is approximately .43429482
ln x = (log x)/.43429482. The greatest solution and it might be worth the 15 bucks or so to get a calculator with e^x and the natural logarithm function.

### I need to add variables on my calculator

To save enter the number you want to save then press [STO] and the variable you want to save to.
And to use the variable you need to recall it by [RCL] button and then the variable you want to recall.
Rate me, thanks.
