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

1 Answer

Entering ln x, and plugging a number in for x value.

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!

    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.

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.

I have a Texas Instruments TI-84 plus silver edition calculator, and I need to know if it has a exponent key?


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.

I forgot how to enter numbers in my TI 84 calculator in the L1 slot


  1. To enter number in a list, say L1, you press the [STAT] key. In the new screen that displays, select EDIT . You will have access to the lists (all the lists) where you will enter the values.
  2. From the command line, you can also open a curly bracket { and start entering values separated by commas. When finished with the values, close the curly bracket }.
  3. Press the [STO>] (store ) button followed by [2nd[ [1] to store in L1.

You can check the version of the operating system by pressing 2ND [MEM] 1. The OS version number is on the second line.

TI-84 plus silver edition. Syntax error on problems such as 8(-)5. How do I get rid of it?


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.
