It seems like a basic algebra problem:
300%(what)=60
3(x)=60
x=20

300%(20)=3(100%(20))=3(20)=60

There is no such thing as a TI89 Plus Silver Edition.

If you mean the TI-89 or TI-89 Titanium, press diamond / (the diamond key below the 2ND key, then the divide key).

If you mean the TI-83 Plus Silver Edition or the TI-84 Plus Silver Edition, press MATH left-arrow 4 .

I cant really read some of the options on the screen on my ti 89....the letters are so blurry......what can i do ?????


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

How do i generate random integers with a ti 89 titanium?


Use the rand() function. If you give it a positive integer argument n, it will return a random integer in the range in the interval [1, n]. You'll find rand() in the MATH/PROBABILITY menu.

Ti85


kinda. The TI-85 programs differently, lacks a table feature, is not upgradable, has redefinable keys, has a larger screen, is smaller, energy efficient, TI-86 semi-compatible, and is older.
The TI-84+ has archive memory, flash-upgradable, FSTN (clearer) screen, 16*8 screen, USB On-The-Go compliant, almost a centimeter longer, assembly language support, and a tad bit faster.

TI-82: $89
TI-83 Plus: $79-99
Free TI-85: $0
TI-84 plus: $119.99
TI-84+SE: $129-139
TI-89 Titanium: $149

TI84


well, the TI-84 does not do derivatives, however, the TI-89 does, if you are willing to fork over the $150 for it. It is definitely worth it if you are planning on taking Calculus BC and/or SAT II for Math Level 2.

Dec to hex conversion


Not sure if TI-89 mode keys are the same, but here's the solution for that calculator:
1. Hit the mode key
2. Hit F3 to get tot Exact/Approx (might be different for 89T).
3. Set it to Exact.
4. Take a look at T-89 manual pages 327, 328, 329.
Nice of TI to NOT include that in the manual, huh?
