If you press the Alpha key twice and type in using the letters written above the keys and spell out "log()" now you can use the log function without searching for the key, then just enter whatever value you have for the function into the parentheses.

You can use the Alpha lock technique for any function in the TI's catalog
ie
nderiv()
csc()
sec()
etc.

I don't think there is one but if you type log(x) on the home screen that will have the same functionality.

Hello,
The wrong terminology is playing tricks on you.

1. If you are talking about the natural logarithms, the inverse function of the natural log is the exponential: ln(e^(x))=e^(ln(x)) = x
2. If you are talking about the common logarithms (log in base 10) to find the antilog of a number, say x, you raise 10 to the power of x.
Exemple: What is the antilog ( that is the name, not inverse log) of 0.345?
Answer; antilog of 0.345 = 10^(0.345) =2.21309471

Look at the last two commands on the screen capture.

Hope it helps
Thanks for using FixYa

There is no such thing as a TI89 Plus Silver Edition.

If you mean the TI-89 or TI-89 Titanium, press diamond / (the diamond key below the 2ND key, then the divide key).

If you mean the TI-83 Plus Silver Edition or the TI-84 Plus Silver Edition, press MATH left-arrow 4 .

### My ti-89 titanium won't graph logarithms (y1=22log(10)x)

The graph of y=22log(10) is a straight line, though it should go through (0,0) and (1,22). Log(10) is a constant 1, so the function is simply y=22x .

If you want "twenty-two times log-base-ten of x", write it as 22*log(x) .

On page 79, you will find:
Find log (x,b). You can enter "log" on the entry line by typing LOG on the keyboard, or by pressing the key with the diamond and then 7.
Press [diamond] 7 X , [alpha] b ) [ENTER]

### I have a ti-89, but my professor is using a ti-83. the ti-83 has a "stat" button, what would that be on the ti-89?

I meant what are you trying to do? There is not a stat button (that I know of) on the TI 89, but I can guarantee you that there is a way to do what you want to.

### Where is the log button on TI-89 titanium?

The natural log is marked LN, the 2ND function of the X key (just below HOME on the leftmost column of the keyboard).

The common log is not marked on the keyboard but can be accessed by pressing diamond 7. You can also access it via the CATALOG and/or spell it out.

### Log & reciprocal functions

There is no log (base 10) button on a TI-89. It's buried in the CATALOG as log(. As a shortcut, you can do ln(#)/ln(base), where # and base are replaced with what you want. For the inverse of a log, do the base raised to the part on the other side of the equals sign. So, log(x) = 2 would become 10^2 = x.
