Re: Ok so I just proved 1 = -1. Someone help me find my error.
I could certainly be wrong, but I think the only problem is in the final division.
I don't see a problem with:
(-1)(V-E)^(1/2) = (V-E)^(1/2)
To use some concrete numbers, I think we all agree that sqrt(4) = -2
Then,
sqrt(4) = -2
sqrt(4) = (-1)*(2)
sqrt(4) = (-1)*(sqrt(4))
I don't believe you can divide both sides of the equation by a root, because it could be either positive or negative.
