TI89 Titanium troubleshooting

The Xres set in the Windows Editor is always greyed out, like other areas that don't pertain to an operation get greyed out....but I can never change the resolution in the Windows Editor. What happened? Thanks

    TI support fixed the problem. I had inadvertantly changed the Discontinuity Detection from Off to ON. Access this through Tools in the Window Editor, scroll to Format (#9 item), then scroll down to Discontinuity Detection and select "Off". Now you have the Xres choice back on the menu of the Window Editor.

It has to be that your have gone beyond mathmatical bounds or the physical bounds of the calculator itself or screen.

I can't turn my ti89 Titanium off. Help!!!

Hi there,

If you are unable to turn it off, try removing the batteries from the back. If this doesn't do it then you need to clear the ram and reinstall the operating system on the device. Instructions on doing this can be found in the user manual.

I am trying to drive a prediction equation. but the book gives directions to aTI-84 and I have a TI-89. I have these steps "STAT, EDIT, L1, L2,STAT, CALC,LinReg(ax+b), ENTER" I have no clue how to make...

I assume you know how to enter data in your calculator. The keystrokes in the following pertain to TI92/92Plus/ Voyage 200 PLT. The main differences with the TI89/Ti89 Titanium is that the function keys F6,F7,F8 are not accessed directly but by the key sequences [2nd][F1], [2nd][F2], and [2nd][F3] respectively

1. CLEAN THE SLATE (so to speak) and ENTER DATA

In Home folder run F6: NewProb to reset the configuration.
Press Apps, and select 6: data/Matrix editor. Select a new data set

Give it a name: here testing.

Press OK/ENTER, The data entry screen opens, enter your values.

When you finish press F2.PlotSetUp.

2. Statistical plot setup and scatter plot drawing

b142867.jpg.

Press F1:define to configure Plot1. Choose Scatter, then choose a mark for the data point. I select 5:Dot. and press [ENTER

Select the data column X=c1, Y=c2

Press ENTER to save configuration. Press [CTRL] [GRAPH] On my TI92 the CTRL key is the [Diamond] key. On the following graph I changed the mark to a cross to see the data point better. I also played with the window dimension. You can also do that with ZoomStat. The graph remind me of a parabola (I know I chose the exact values)

3. STATISTICAL CALC. AND REGRESSION ANALYSES.

Now we have to find the equation that fits these data best.
You press APPS 6:Data/ Matrix editor but you select current to return to your data set. You are taken to the data entry editor (Figure 3 above). In that screen Press F5:Calc to edit the type of statistics you want

On first line select the type of regression model : Linear Regression, QuadReg quadratic regression (or anything else available) X is from column1, Y is from column 2. Store RegEQ The regression equation in say Y1(x)

7c9f572.jpg

Press ENTER to save to get the Regression Equation. Here it is
As you can see I cheated: a perfect parabola. R^2 =1.

And here the best fit represented on same graph as the statistical data

Usually you have to try different regression models, until you find the one that fits best the experimental data.

TI89 Titanium--main board replaced,must get its serial number

I am not sure if the number on the case is the one required. The TI89 Titanium and other recent TI machines have a unique ID. To get it, turn the calculator ON, Press F1 select 3: About.
On the subsequent screen, one finds various bits of information among which is a product ID and a 14 digit hexadecimal number ID ( a number in base 16, with Arabic digits 0 to 9, plus and A, B,C,D,E, and F)

The same number can be revealed by TIConnect software:
After machine is recognized, click TI Device Info. The Device ID is returned under General Information Tab or ID list tab.
This device ID could be the one needed for the Calculus Made Esay. software

I received this solution, but at the end the calculator asked me about some invalid certificate. Now the ti 89 is stuck at the boot screen because if I retry, it goes thru the whole process again and asks...

Hello,
The answer I gave you was taken verbatim from the TI FAQ and knowledge base. I copied and pasted the part relevant to you calculator.
In any case, I sent an e-mail message to [email protected], giving the link to your original question and my answer to it. I took the liberty to copy/paste your present message. I also asked about that invalid certificate.
All we can do know is wait for their reply.

Setting modes

Hello,
There is no such command for the TI89Platinum/TI92/TI92Plus/TI Voyage200PLT. This command exits for the TI83Plus/Ti84Plus and it allows you to get the r2 value for a regression. For the TI89 r squared is calculated by default.
Hope it helps

My ti89 titanium doesn't turn on

I had the same problem. I changed the batteries and it didn't work. I took out the batteries for about 30 minutes, and then put them back in, and it turned on.

Calculator quick working

Mine did the same thing and I was told by Texas Instruments that I can send it in for repair--for $81 since it is more than 1 year old.
