7 button doesn't work
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.

How do I put in Sin^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.

Wha is a percentage number of another of another
Hmmm. Could you give more details? Are you wanting to find a percentage? If so, here's an example - 10% of 100 is 10.
Multiply 100 by .10 = 10.
So to find the percentage of a number, multiply the number in question by the decimal version of the percentage. 8% is .08, 15% is .15, etc.
I hope that helps!

Replaced 4 AAA batteries AND NOW THE SCREEN IS ALL DARK
Hello; TI is not my favorite. The calcylater is for keeping tabs on yjr number of batteries used in a given time. Kidding!. Make sure,you probably alreay have, the batteries are installed correctly. No offense, It happens. The negative (flat) of the battery always goes against the spring contact. As you put the batts in, rotate each one several times to ensure it is seated and making good contac. Make sure the device is off when messing with the batteries.all batteries should be new or at least in same condition. If there is a bad one it will try to balabce and affect the others.. Look for a reset pinhole, Usual place is on the back. A small paper clip placed in this hole and press until a ckick will may be the need. Doesn't take much pressure so take care not to Gorrila the thing. _Good Luck-Ned-
