We express the superconducting gap \ensuremathΔ(T) in terms of thermodynamic functions in both s- and d-wave symmetries. Applying to Bi2Sr2CaCu2O_8+\ensuremathδ and Y0.8Ca0.2Ba2Cu3O_7\ensuremath-\ensuremathδ we find that for all dopings \ensuremathΔ(T) persists, as a partial gap, high above Tc due to strong superconducting fluctuations. Therefore in general two gaps are present above Tc, the superconducting gap and the pseudogap, effectively reconciling two highly polarized views concerning pseudogap physics.
