Try using the EE key near the bottom left. It's the exponent key, so if doing EE (-6.60) doesnt work, try doing 1 EE (-6.60).

How do you square on a ti 89 titanium


One way is to multiply the quantity by itself.

Another is to raise it to the second power using ^ (just above the divide key).

You can also take it's logarithm, double it, then take the antilog :-)

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).

How do you use the -log function on the TI-30XA calculator? I downloaded the manual and there is no instruction for finding the -log of a number


Do you mean the antilog? For the common antilog, use the shifted function of the LOG key (marked 10^x). For the natural antilog, use the shifted function of the LN key (marked e^x).

For example, to calculate the common antilog of 0.5, press . 5 SHIFT [10^x] = and get about 3.16. To calculate the natural antilog of 0.5, press . 5 SHIFT [e^x] = and get about 1.65.

Where is the anti log button on my Ti- 30x?


Common antilog is the 2nd function of the LOG key, natural antilog is the 2nd function of the LN key.

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
  1. the common logarithms (log in base 10),
  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.

How do I calculate the inverse log on the TI-89?


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.

How to calculate the antilog please


The antilog is the inverse of the logarithm. Not too surprisingly, it's invoked as the 2ND shift of the appropriate log key.

For the common antilog, use the 10^x key (2ND LOG). For example, 2ND LOG 3 ENTER gives 1000 as the common antilog of 3.

For the natural antilog, use the e^x key (2ND LN). For example, 2ND LN 3 ENTER gives 20.08553692 as the natural antilog of 3.

Find the antilog on the TI-83 Plus for finding pH in chemistry problems


I reccently had the same problem, but I have a Ti-84 Plus,and I am disgusted by how poorly this matter is covered by Texas Intruments. Esp. since the solution is rather simple.

The antilog key is [2nd] [log] or the 10^x. On your screen it should apear as 10^( and then you just input the value that you want to find the antilog of.

When used to solve pH problems remember to input the pH value as a negative number, since pH= -log[H+] then [H+]= antilog(-pH).

Hope that helped))))) ^^
