Hi. I own a Casio fx-9750G PLUS and I am having some problems with it.
If i go to the Menu --> Stat --> Fill in list 1 and 2 with the correct numbers from a task i have got --> calc --> Reg.
then when i am going to find witch function is the best for the numbers i have filled in I can press --> x/x^2/x^3/x^4 to see witch is the most correct. when I press "x" it works just fine. I get all the information I need. But when I press all of the others(x^2, x^3, x^4) I don't get the " r2= ". And i need that to see if the function is correct or not, because r2 should be as close to 1 as possible. how can I know witch one to use if I only get r2 on one of those!? Do I have to do some programming to get r2 on the others to?
I Need your help!
(excuse my english, I know it's not the best)
