Let f: R->R. If f is infinitely differentiable and analytic on a dense set is f analytic? Is this true if we restric f to [0,1]?
note: by analytic I mean the radius of convergence of the taylor expansion is non-zero about every point.
Maybe this is simple but I was thinking about it and can't figure it out
