A class of Nonmonotonic Continuous Functions
Abtract In this paper,we discuss several properties of functions ,i.e .continuity, differentiability, monotonicity, integrability.we consider the relations between them and give some results.
Key words continuous function, differentiable function, monotonic function, integrable function, Weierstrass function.
