+A function is complex differentiable at a point if its derivative exists in the complex plane, behaving smoothly akin to a [real differentiable](/wiki/real_differentiable) function. This powerful condition implies profound properties, making such functions automatically infinitely differentiable and analytic, a core concept in [holomorphic function](/wiki/holomorphic_function) theory.
