Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator

I'm trying to enter ln x on my TI-84 Plus silver edition. I have the numbers I would like to plug in, in order to graph this funtion. They are -2,-1,0,1,2. But whenever I push ln, and enter the number in the parantheses, it comes up with error. What am I doing wrong? Please help!

Having gone over a month with no response, I assume this is no longer a problem.

That is what I get with your numbers on the TI84 Plus Silver Edition 0.1870313608. I get the same on the TI83 Plus. What can I say?. Apart from an error entering the numbers ( a 6 for a 9, a 3 for an 8) I cannot think of anything else. Sorry.

If you want to raise a number to another, use the ^ key located just above the divide key.

For natural antilogarithm (exponentiation of e), use 2ND [e^x] (the shifted function of the LN key).

For common antilogarithm (exponentiation of 10), use 2ND [10^x] (the shifted function of the LOG key).

To enter a decimal exponent as part of a number, use 2ND [EE] (the shifted function of the comma key, located just above the 7 key.

If you want to subtract 5 from 8, enter it as 8 - 5.

The - key to the right of the 6 key is for subtraction, the (-) key to the right of the decimal point key is for entering negative values.

Make certain you have registered your calculator on their site. I think you need to enter you internal number. The internal number can be found by pressing the 2nd key, then the plus key and choosing about in this screen.

What does the error message say? That would help us diagnose your problem.

Off the top of my head, I see three potential problems.

1. The logarithm of 0 is infinity. Trying to calculate this will produce a domain error.

2. The logarithm of a negative number is a complex number. If your calculator is not set to one of the complex modes will produce a nonreal answer error.

3. Using the - key instead of the (-) key when trying to input a negative number will produce a syntax error.
