How to find antilogs on ti-30xIIs - Texas Instruments Office Equipment & Supplies

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).

In case of difficulty TI 30Xiis :

The antilog functions are the 2nd functions of the log functions on the top row of the keyboard.

To calculate the natural antilog of 3.1, press 3 . 1 2nd LN
To calculate the common antilog of 3.1, press 3 . 1 2nd LOG

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.

On a TI-30XA the EE key is just above the 7 key.

On a TI-30XIIS the EE is the shifted function of the key just above the 7 key.

If you want to raise e to a value (natural antilog), use 2nd [e^x]. e^x is the shifted function of the LN key in the leftmost column of the keyboard.

If you want to raise one value to another, use ^ located above and left of the 7 key.

For common antilog use 10^x. For natural antilog use e^x. These are the shifted functions of the two keys immediately below the 2nd shift key at the upper-left corner of the keyboard.

I'm not specifically familiar with the TI83 or TI84 but I've used a lot of TI calculators in my time, so I'll give it a try. If your trying to find the antilog of a number in base 10 enter the number and hit the (10 to the X) button. If you're trying to find the antilog of a number in in base e (natural log), enter the number and hit the (e to the X) button.

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))))) ^^
