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

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

Hi,
A 6ya expert can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
The service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
Good luck!

### Cant find ! button

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.

### 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?
