We study the topological pressure of a continuous transformation T with finite topological entropy on a compact metric space X . We give a family of examples which have a unique tangent functional at the constant function zero and the unique tangent functional is not ergodic. We obtain several necessary and sufficient conditions for the pressure of T to be Fréchet differentiable at a given f ɛ C ( X ).
