I know I am really way behind , using tc 12 and deluxe version at that. All I have for now. Have trouble when I go to use a feature I see in the program or read about somewhere in forums or instruction manual , and it doesn't work or not? My calculator works but can't figure square root with the functions ?? Can do simple math like , 10*3 = but if I select a function from pop up -say "abs(x) " and I enter" -3" replys" *error*" I would love to be able to find square roots on this machine! Is it only in TC pro ver , which I find it says at the top of the subject line in the manual files?
It sounds like you have the calculator, but aren't using it right. There's only 3 help screens on it, so it really doesn't take long to read. I don't think it would taunt you by offering to do a function that you didn't have access to.
When you typed abs(x) without defining 'x', you got an error because x was undefined.
But if instead, you go into the function box and type
you should see your answer. Or if you type
you should see the square root of 5. (2.24)
Now let's say you wanted to do several square root calculations in a row. You could type
x = 5 <enter>
in the top of the calculator. Now Below you'll see a field with 'variable' x and another field with value '5'. Now enter at the top:
answer = sqrt(x) <enter>
Now if you go down to the row in the calculator where variable 'x' is defined and enter '100' in the value column, you will see the next row where variable 'answer' is defined change its value to '10'
My question is, once its given me the square root, how do I copy the result out?
