We express the superconducting gap Delta(T) in terms of thermodynamic functions in both s- and d-wave symmetries. Applying to Bi2Sr2CaCu2O8+delta and Y0.8Ca0.2Ba2Cu3O7-delta we find that for all dopings Delta(T) persists, as a partial gap, high above T-c due to strong superconducting fluctuations. Therefore in general two gaps are present above T-c, the superconducting gap and the pseudogap, effectively reconciling two highly polarized views concerning pseudogap physics.
