Texas Instruments Recent Questions, Troubleshooting Help & Support

Hi,
You will have to report faithfully the message returned, you cannot use your interpretation of the message. Error messages are codified. Each one will correspond to very particular error conditions. I did check the manual for all possible error messages and there is none that states wrong info.

My hunch is that there are errors in your data, but I can't say what type of error: I do not have the actual message returned. Verify you data, item by item, and try again.

To make sure that the calculator is well configured to do statistics

1. Press [STAT][5:SetUpEditor][ENTER]
2. Press [2nd][0] (CATALOG) and press [PRGM] (C) to jump to the first command starting with C.
3. Scroll down to [ClrAllListsts] and press [ENTER]
4. Calculator replies Done

Restart your statistical data entry.

Hope it helps.
Thank you for rating this solution

How do I clear off fix (rounding) mode on the TI-10 and TI-15? In order to clear Fix off the calculator just press the following keys- First press the [Fix] key- Next press the [.] decimal key

https://www.dummies.com/education/graphing-calculators/10-common-ti-84-plus-error-messages/

1. Press the "2nd" key.
2. Press the x2 function key.
3. Enter the number.
4. Press the close-bracket key ).
5. Press the ENTER = key.

Sorry, but you cannot. However there is a program that you can download and install on your calculator. YOU DO THAT AT YOUR OWN RISK.

Thanks! Genius!

Error 07 is Syntax Error. From the manual: "You entered a value; look for misplaced functions, arguments, parentheses, or commas; check the syntax description in the A to Z reference."

If you can't find and fix the error, could you post the expression producing the error?

Make sure the battery contacts are clean. I just fixed mine, as it had been sitting for some years and the batteries went bad.

I gently cleaned any "green mold" from the contacts with a light Scotch-Brite pad and some electrical contact spray that I got at a local hardware store.

I tested the batteries with my digital meter to make sure they were 1.5V or more and put everything back together. Works great!

Give it a whirl---this is a nice little calculator. I bought mine in 1990-1991 and it's gotten me through undergraduate and graduate school...

If You Want to Convert Decimal to Fraction for your maths class. These types of calculations are we can learn on 5th to 10th Standards. If you are studying in 5th to 10th class and you don't know how to convert your decimal number to fraction number. You want to learn about decimals and fractions. https://www-calculator.com/

Your calculator is set to radians, which is the norm for higher mathematics. To set it to degrees, press MODE to bring up the mode editor, press down-arrow twice to get the the angular mode, press right-arrow to highlight "DEGREE," and press ENTER. Press 2ND [QUIT] to exit the mode editor.

I'm assuming the lack of a response means using the proper key did the trick.

Make sure both sides are snapped down firmly

The quick way to determine absolute value is to square the value and take the square root of that. So on the TI, with the value on-screen, just push these 2 keys in sequence (they are right next to each other):

I had the same problem. However, I learned: Press the upper light blue button, Reading: 2nd and then press: the ON button. This method shuts mine off.

See angle unit setting below

I had this same problem on my TI 89... You must have accidentally set your calculator to insert mode. To switch it back to the thin cursor, input the following keystrokes... Go to the "2nd" key to enter second function mode. Then press the button with an arrow on it pointing to the left(The key that you use to backspace). Do you see the "INS" lettering above the backspace key? There's your solution :-)

What are you trying to do? The syntax you use depend on what you want to achieve.
Indefinite integral : Integral( ln(x),x) gives the correct answer xln(x)-x
Definite integral : Integral(ln(x),x,1,2) gives the integral of ln(x) between x=1 and x=2
Definite integral between 1 and y : Integral (ln(x), x,1,y) gives the correct expression yln(y)-y +1

By inserting the =0 you are in fact assigning the result of the integration to value 0, and the calculator calculates the integral and assigns 0 to it. This is what my TIVoyage 200 PLT gives me:
{Integral((lnx),x,1) = 0.} returns {x.ln(x)-x+1=0}
which is an equation.
