Hey shrestha,

I've never seen a calculator with display clarity problems.

The only option I could think to offer you is to attempt to adjust the contrast. However, I'm not sure whether or not your TI-89 actually has an option to change the contrast. Because I own a TI-89 Titanium - and although its a wonderful calculator - it does not allow the user to alter the darkness/brightness of the display.

Call Texas Instruments: 1-800-TI- CARES...They are pretty helpful with common questions like this.

Sayonara,

I would really appreciate it if you could tell me how I can find exponential regression using a TI-89 Titanium Graphing calculator. Thank you very much :)


The ExpReg command is in the MATH/Statistics/Regression menu. The first two arguments are lists containing the x and y values. An optional third argument is a frequency list. Two additional optional arguments are lists of category codes and a category include list.

Full details are in the manual under ExpReg, page 819 in the version available at

I have a Ti-89 and my screen is really dark all of a sudden. I cant figure out how to lighten it! I can read it, but only if i turn it just right and look at it up close. How can i lighten it?


Lighten the screen by holding down the green diamond key and then holding down the - key. If you go too far, use the + key instead of the - to darken the screen.

When I turn the switch on, ti-89 titanium does not turn on.


If you connect calculator to computer using Ti connect device explorer you might be able to see what files are on the calculator. I don't know if you downloaded from the web but, 3rd party programs and shells tent to miss up the calculator. This would able you to delete out possible problems which could be re installed later.
