My number 1 key on the numberpad is stuck

Step 1:
What sort Of stuck ?

A stuck key on a keyboard is one of those annoying things. The typical desktop keyboard has about 104 keys, a laptop keyboard has a few less. The problem of a stuck key can be a hardware or a software problem or the key itself might be the culprit.

Hit the key several times. This will almost always unstuck a key. Clean the keyboard with an approved keyboard cleaner. These often come as wipes. People sometimes spill food and drink that can make keys sticky. Pop the keys out using a small knife or flathead screwdriver. Most keys pop right out and can be pushed right back in place. Look for something that might be blocking the key and remove anything you find.

Where is factorial button on ti-83 plus

Not every function on the TI83Plus calculator has a dedicated key, or is accessible through a key sequence. Among the keyless function is the factorial function.

To access the factorial function
  1. Through the catalog of commands: press [2nd][0] (CATALOG) and scroll Up till you reach the exclamation mark !
  2. Press [MATH]. Use right arrow to highlight PRB menu. The factorial function is the 4th in the list.

Type the number and use one of the foregoing access methods to echo the exclamation mark on the home screen and press ENTER.
Ex: 12! =479001600

The largest number that you can use with the factorial is 69.

Hope it helps.

Interpolation on TI 89

No you don't have to download a interpolations program, you can enter it in as a function like this:

:yy1+(yy2-yy1)*((x-xx1) / (xx2-xx1))

How I do it is, I put it in a folder dc so, you create a folder name dc

2nd key then - key which will be the VAR-LINK key
hit F1 key then the 5 key to create a new folder. Type in what you want to call your folder in my case dc and hit enter.
Hit APPS key then 7 key then the 3 key, then you see the word program highlighted open it up and change to Function hit enter.
Then slide down to your new folder you just created in my case dc, once you find it highlight it and hit enter.
slide down to variable and type dc and hit enter.
Next, type in or make it look like this:


Now when I'm at the home screen in the main folder, I type:
And I get 40 for my answer.
Here's my logic:
0,0 is the starting point, let's say my circuit max voltage is 5 volts and my max resistance is 100 ohms. I want to interpolate or know how many ohms I would have if my circuit measured 2 volts, which is 40 ohms.
Now if I had ohms and wanted volts I just set it up like this:
which equals 2 volts
i hopethis helps you. raklein62
