The problem looks something like this:

Find the limit as x approaches 2 of (6-x)^(1/2) -2 divided by (3-x) ^(1/2) -1.

The problem in words is: the square root of (6-x) minus 2 divided by the square root of (3-x) minus one.

the answer should be 1/2 but i keep getting it wrong. How am i suposed to multiply it?

Since the Theory came more close to practical, nd the only problem is the amount of electromagnetic energy to create an anti-gravity room on earth, then how much energy are we talking about?

NASA trains the astronauts by taking them real high in a plane then dive down them, that they feel an apparent effect of weightlessness, to get them used to zero gs.

Since its practical to create an anti-gravity room, by lets say 5 m^3 dimension, How much ENERGY are we talking about that they do'nt even try to build it? or even if they are, am not aware of.

tnx fellas
