  We present a set of explicit trial wavefunctions for the filling factors
\nu=n/(2n\pm 1) and \nu=1/2 in the symmetric gauge. We show that the zeroes of
the wavefunction, except those dictated by the Fermi statistics, are detached
from the particles. The evolution of zeroes as the filling factor is varied is
examined. We show that the wavefunction at half-filling exhibits a 2k_F-like
oscillation in its occupation number profile. The center-of-mass motion of the
ground state droplet is described in terms of the intra-Landau- level
excitations of composite fermions.
