Uncertainty principle

okay, thanks to you two!

so, deciding whether one has to use an equation like ΔxΔp=h/2 or ΔxΔp=h, which are probably in most cases also inappropriate, is impossible, if the actual wavefunction of the underlying experiment is not known. thus, maybe the guys who wrote this book calculated the actual uncertainty by using this more elaborated structure of quantum mechanics and gave us these equations, so that we could get an impression of the dimension of uncertainty in these experiments? ergo, one would have to calculate the uncertainty by using the mathematical apparatus of quantum mechanics in order to get it right? is this what you meant?
