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!

press menu, there it says science or something like it

set it on float

so --what is the question? this is not a forum for dribble

sin^2(x+2) is the same as (sin(x+2))^2

sin(x)^2 sin^2 and its kkn are an unusual notation, compared with other functions. For example, you don't write log^2(x) but instead log(x)^2.

Press the S<>D key to toggle between symbolic and decimal notation.

TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

If that doesn't work, post a comment here and we'll go on to the next step.

There are 1.609344 km in a mile. So, the following statement is true:
$8 000 000 = 1.609344km
Now bring it down to One km, rather than one and a decimal by dividing both sides of the equation by 1.609344.

8 000 000/1.609344 = 1km.
You wind up with the following:
$4 970 969.5378986717569394734749065 / 1km.
(obviously, round it to a normal dollar figure, rather than to hundredths of thousandths of cents)
You wind up with $4 970 969. 54 per kilometer.

Having gone over half a year without a response to my query, I assume my suggestion to adjust the screen contrast solved the problem.

Hi,

This means both your Xscl and Yscl values are too small. Fix this on the WINDOW screen, as explained under My screen is covered with horizontal or vertical lines.

Thanks

Fame !

If it's just a single line then it sounds like that the screen is not connected probably or is shot...

if it's more of a "flurry" or snow... then you can connect to another unit via the I/O cable or usb if your model has it, and use the "send OS" command to start from scratch and lose all data but have a working calculator.

What is wrong with the screen?
