The square root of VA might be W for a quite different reason, if I got him right. Also, VA as we know him is a real entity, not an apparent one. :-) As an electric engineer and knowing Valentin, I can only share your point :-) In one of his famous S&SMC , Valentin asked to find a solution on the HP-71B to the equation: Abs(Ln(x*x)-Ln(x^2)) > 4.012007 (BTW, I found a solution ...) In the same way, is it possible to have square of VA significantly different from the product of VA by VA? Let's take all this with humour... :-) J-F |
