WebIn the case of Weierstrass's non-differentiable function W(x) = ∑∞n = 0ancosbnxπ where 0 < a < 1, [and] b is an odd integer and ab > 1 + 3π 2 (1 − a), I show that S(l) and S(u) are enumerable, so that C is not empty. Also it is shown that C can include only the proper maxima and minima, so that C is at most enumerable. WebStatement of the Weierstrass Approximation Theorem. Let f: [a,b] → R be a real valued continuous function. Then we can find polynomials p n (x) such that every p n converges uniformly to x on [a,b]. In other words, if f is a continuous real-valued function on [a, b] and if any ε > 0 is given, then there exist a polynomial P on [a, b] such ... porsche repairs east greenwich ri
