giving the equation a Y and not an X?
I have a bunch of equations that I need to be able to evaluate both ways. The documentation I am working from gives the formula for getting the Y, but I need to reverse it to get the X.
so I have Y= x2+5, and I put in X=2, I get 9.
What I want to do is put in Y=9 (9=x2+5) and get 2...
Any help is greatly appreciated.
