Our aim is to show that most well-known classes of nondifferentiable functions are in some sense quite smooth. Nonsmooth analysis (for short, NSA) is one of most attractive and promising areas in modern mathematics. A lot of new profound results have been obtained and much more seem to come (see, e.g., [1–6] and References therein).
