I am trying to figure out how to use the absolute value on my TI-89 Titanium. Example: |4x-5|=|3x-23| How do I put this in my calculator to get the answer. THANK YOU!

For example y=x^(1/3)-x+1. Type this function and then graphing it!

The distributions do not exist on the TI 89 Titanium. But you can download an application from the education.ti.com website. It is called tistale.89x. Here is the link to it.

If you want to graph the absolute value of a function, feed the function to the absolute value ie graph y= abs(f(x)). The calculator will take care of it. See screen captures where I draw the function y1=x^3-5x^2-3 and y2='x^3-5x^2-3'. On the first graph the function is represented and on the second the function and its absolute value.







The calculator knows how to calculate the absolute value of an expression. The name of the command is abs(

Hi kelsers,

You need to re-install your calculator's OS. After this process your Ti 89 Titanium will operate properly. If you do the process below make sure you use new batteries.

Warning!!! If you do this procedure make sure that your computer and, calculator are connect. Use Ti Connect software and, make sure you can install the OS on the calculator without any interruption. At any time even at the very beginning of this process, if your computer or, calculator gets interrupted or you have a power failure during the installation of the OS, your calculator will be destroyed. So not attempt this procedure during a thunder storm.

You can use the Ti OS Downloader but, you will have no idea what OS is stored by the Ti OS Downloader. So, I suggest following my instructions and, installing the newest Ti 89 Titanium OS 3.10v.

Procedure to installing the newest Ti 89 Titanium OS 3.10v.

You can also get the latest copy of Ti 89 Titanium OS 3.10v by going to the Texas Instruments web site. You can get to that site instantly by clicking, "Ti 89 Titanium OS 3.10v." Once your at the Ti site click the Download Item, Ti 89 Titanium OS 3.10v. Next you can login or, click "continue as guest". I'd would click the "continue as guest". Once you have click, "continue as guest" the Ti 89 Titanium OS 3.10v. will download to you. Click, "SAVE". And then a folder will pop up. It is probably a folder that you download too. If so, you may want to change it and, "Save as" to this folder, "My Documents \ My TI Data \ Downloads". You can also go back and, download the Ti 89 Titanium guidebook too, if needed.

Link your computer and calculator with the USB cable or, Direct Black Link cable that came with the calculator.

Remove one of the AAA batteries. Press and hold the [APPS] key, and while holding the [APPS] key, replace the battery and turn the unit on. On the older TI-89 you should see "Press I to install code...", and you should press the [9] key to continue. But, on your Ti 89 titanium it should say, "Waiting to receive..." or, "Waiting to received OS...". Now you need to follow the instructions in the paragraph below to restore the calculator's operating system.

Next, drag the Ti 89 Titanium OS 3.10v. that you copied earlier to "My Documents \ My TI Data \ Downloads" out of that folder and, drop it in the "Ti Connect" icon on the desktop. Next the OS Downloader Warning will pop-up. Click, "OK" to continue and, the new OS will begin to install. The Ti Device window should pop up and, click on to the port where your Ti 89 Titanium is located, USB1 cable or Direct Black COM1. Just click, "Select" and, the OS will continue to download. Upon completion the newest Ti 89 Titanium OS 3.01v. will be installed.

Set your calculator to RAD mode and then graphing functions.
See example for y=sin x

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

(2m^3)(3m^-1)^3/(3n^3)(5n^2)'

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.

2nd and f6 or something...
make sure minimum and maximum values aren't mixed up!
