20 Most Recent Texas Instruments TI-83 Plus Calculator Questions & Answers

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.

the area of your roof is equal to the base (B) times the hight (H) divided by 2.
A = ( B x H )/ 2 = 120
To get the Perimeter of your roof you need to sum the base plus the sides (S)
So P = B + 2 x S

if you have a slope degree of 30 then
B/2 = cos (30) x S
so P = B + 2 x B / 2 / cos(30)
P = B ( 1 + cos (30) )
we also know that
H = tg (30) x B/2
from this last one we can go back to the Area and get a value for B
120 = ( tg (30) x B / 2 x B) / 2
480 x SQRT(3) = B^2
B = SQRT(480/tg(30))

P = SQRT(480/tg(30)) x ( 1 + cos (30))
tg (30) = 1 / SQRT(3) cos (30) = SQRT(3)/2
P = 2 SQRT(30 x (12 + 7 x SQRT(3) ) ) or aproximately 53.8m

i had the same problem. If you hit 2nd down 2nd down 2nd down and keep repeating untill the screen clears it should solve the problem. i tried the other solutions that tried clearing the memory and they didnt do anything but erase the equations i had previously put in it (great). But this should work.

Press any key (except for 2nd and On), and the message should disappear.

For cube roots, use the cube-root function in the MATH menu. For example, to calculate the cube root of 8, press MATH 4 8 =

For other roots (including cube root), use the xth-root function in the MATH menu. For example, to calculate the fifth root of 32, press 5 MATH 4 3 2 =

You should learn about scientific notation. The two values are the same, just written differently.

If you're talking about your laptop, try to gently remove the button and clean it with a laptop cleaner. spray a bit of it on a small piece of cotton until its damp, not wet, and clean the area, and put the button back on. If it is infact something wrong with the sensor take it to a local computer store. If you're working with a mac, apple should have a solution for you.

You have attempted to use, edit, or delete an archived variable. For example, the expression dim(L1) produces an error if L1 is archived

this happened to me as well. i looked it up and heres what i found:

basically you have a stat plot on so to turn it off, press 2nd and then the Y= button to get to "Stat Plot"
one of them is turned on so press enter and select OFF. this should fix the problem!
