Abstract

Piecewise smooth function is a wellknown illustration of the semismooth function. The set of nonsmooth points of piecewise smooth function f partition the space locally into many related components. This thesis also illustrates the prove of the theorem and Lemma dealing with piecewish smooth function f derivative analysis locally by Lipschitz. Piecewise smooth function f is differentiable in x with f(x) = fi (x). So f continues at x if it is close to f Concequently f smooth is at x
