20 Most Recent Texas Instruments TI-89 Calculator - Page 6 Questions & Answers

If you have a cable to hook up to your computer then you can re-send it, or if you have a friend who has the STAT program they can send it to you with the cable that came with the calculator (I think, it did with the Titanium)

Hi,

Sorry to hear that. This problem may appear due to pressure on the LCD (Liquid Crystal Display) screen. However, it can occur by itself if it gone bad already. The only remedy for this problem is to replace the LCD or check if it has an inverter and replace it.

Hope this helps.

I do not know of any TI calculator with Model number 53, but I will try to give a general answer. If you get a window range error that means that the Window limits are not set correctly. For example, the lower limit in X, Xmin must be algebraically smaller that the upper limit, Xmax. The default for the TI graphing calculators are Xmin=-10, and Xmax=10. Similarly the Ymin must be smaller than Ymax. The default limits for the y-variable are Ymin=-10, and Ymax=10. If your calculator has a Zoom function ( if it is a graphing calculator, it must have it) then Press Zoom key and select Zoom Standard or ZoomStd.

write the first number all inside a parenthesis. Then push divide. And put all of the bottom inside another parenthesis. This is what you have to do for all multistep division problems on these calculators because they go step by step from left to right.

1. In Home screen, Press [2nd][F1] (F6) to open the CleanUp menu.
2. Press [1:Clear a-z] or [2:NewProb] and press [ENTER].
3. After the calculator displays Done, Press the [MODE] key.
4. Navigate the pages till you find the option Exact/Approx.
5. Select EXACT.
6. Return to the Home screen and type in your integral, using the syntax $( f(x), x) and press ENTER. Here the dollar sign stands for the integral sign.
7. If you want a definite integral, the syntax is $( f(x), x, lower_bound, upper_bound).

Here is a screen capture with a few examples.

You can follow the detailed instructions shown below

Hope this helps.Your valuable feedback would be appreciated.Thanks.

Having gone over half a month without a response to my query, I assume my suggested reset solved the problem.

Enter the binary number with a 0B prefix.

your value is not within the domain of the function, that is why it's giving you that error message, try the value times -1, or -(your value)

As you well know (?) the application Calculus Made Easy is not free. So, if you deleted yours, I suspect you have to contact the Application Vendor to allow you a new download, or send you a disk.
Once you delete something from the calculator there is nothing you can do to recover it. Sorry.

Yes. Hit ↑ on the homescreen and scroll down with ↓.

Try clearing the memory, 2nd + 7-1-2

Press MODE to bring up the mode editor. Press F2 to get to the second page. Use down-arrow to move to the "Exact/Approx" line. Press right-arrow to bring up the options. Use up/down-arrow to highlight "APPROXIMATE." Press ENTER twice.

What probably happened is the graph was turned off. to turn the graph back on, select the function (ex. y1) and then press f4. This should turn the graph back on and you should see the function.
Hope this helps.

Press 2ND [square-root] 1 4 5 ) ENTER.

square-root is the 2nd function of the divide key. If the answer shows up as square-root 145, press diamond ENTER to convert to decimal.

Actually, you are getting an exact number (try writing 1/7 as an exact decimal number). If you want to convert a single result to its decimal approximation, press diamond ENTER. If you want all results to come out in decimal, press MODE, F2, then down-arrow to the "Exact/Approx" line, press right-arrow, select "APPROXIMATE", then press ENTER twice.

New batteries? Take the batteries out and put them back in.

log isn't marked on the keyboard, but you can access it by pressing diamond 7. Of course it's in the catalog, and also it can be spelled out.
