In this paper, the thermodynamic properties of a rotating Bose-Einstein condensate confined in a harmonic plus quartic potential are calculated using a modified semiclassical approximation. We determined the condensate fraction, critical temperature and heat capacity of the condensate using a method that takes into account deviations from ideal gas behavior due to the effect of finite size and the chemical potential when it is equal to the ground state energy (positive chemical potential). Predictions that can be directly compared with experiment have been found.
