    "abstract": "We propose a simple variational form of the wave function to describe the\nground state and vortex states of a system of weakly interacting Bose gas in an\nanisotropic trap. The proposed wave function is valid for a wide range of the\nparticle numbers in the trap. It also works well in the case of attractive\ninteraction between the atoms. Further, it provides an easy and fast method to\ncalculate the physical quantities of interest. The results compare very well\nwith those obtained by purely numerical techniques. Using our wave function we\nhave been able to verify, for the first time, the predicted behaviour of aspect\nratio.",
