  1. Informally, the Weierstrass Approximation Theorem (WAT) asserts that any continuous function on [a;b] may be approximated uniformly well by a polynomial function. It is one of the most important results in Analysis. To state the WAT precisely we recall rst that C[(a;b)] is a metric space, with distance function d(f;g) = max x2[a;b] jf(x) g(x)j

R can be approximated by a polynomial with a maximum error as small as one likes. There are several approaches to provin Satz von Weierstraß. aus Wikipedia, der freien Enzyklopädie.

Folgende Sätze werden nach Karl Weierstraß als Satz von Weierstraß bezeichnet: der Satz vom Minimum und Maximum zur Existenz von Extrema. der Satz von Bolzano-Weierstraß über konvergente Teilfolgen The Weierstrass approximation theorem One of the most important ways in which a metric is used is in approximation. Given a function f, finding a sequence which converges to fin the metric d∞is called uniform approximation.

In this paper we mainly consider two of Weierstrass' results. The rst, Weierstrass [1872], is Weierstrass' example of a continuous nowhere di erentiable function. It is a generally accepted fact that this was known and lectured upon by Weierstrass in. proof of Weierstrass approximation theorem proof of Weierstrass approximation theorem To simplify the notation, assume that the function is defined on the interval[0,1]. This involves no loss of generality because if fis defined on some other interval, one can make a linear change of variable which maps the domain of fto [0,1] The Weierstrass approximation theorem states that polynomials are dense in the set of continuous functions. More explicitly, given a positive number and a continuous real-valued function defined on , there is a polynomial such that .Here is the infinity (or supremum) norm, which in this case (because the closed unit interval is compact) can be taken to be the maximum

  3. The Weierstrass Approximation Theorem. In part 4.5. we already used the Lagrange interpolating polynomials to connect given points in the xy-plane. The main issue then however was to capture finitely many values exactly. If these values are values of a function we normally have no idea how acurate its other values are hit.. This part now will prove that polynomials are able to match any.
  4. Weierstrass Approximation Theorem For every continuous function f(x) on [a;b] and every >0 there is a polynomial P(x) such that jf(x) P(x)j< for each x2[a;b].

Given x ∈ [0, 1], let X ∼ Binom(n, x), and define the Bernstein-polynomial of degree n by B n(x) := E h f X n. Weierstrass's theorem with regard to polynomial approximation can be stated as follows: If f(x) is a given continuous function for a < x < b, and if e is an arbitrary posi- tive quantity, it is possible to construct an approximating polynomial P(x) such that 1f(x) - P(X)I < E for a ? x < b.

Weierstrass Approximation Theorem. To begin, Section 2 of this paper introduces basic measure theoretic concepts. It rst gives the de nition of a power set and uses this to de ne a ˙-algebra which is essentially a subset of a power set. Every set in the ˙-algebra is de ned to be a measurable set which means that there exists some way to assign a real positive number from 0 to 1to every such. Approximation theory, as you might guess from its name, has both a pragmatic side, which is concerned largely with computational practicalities, precise estimations of error, and so on, and also a theoretical side, which is more often concerned with existence and uniqueness questions, and \applications to other theoretical issues.

The purpose of this monograph is to present its true nature by proving several increasing generalizations of this theorem, going from the classical case of subalgebras to submodules and to arbitrary subsets of continuous functions over compact spaces.

WEIERSTRASS' APPROXIMATION THEOREM 3 Proof of Theorem 1.1. For f 2C[a;b] we extend the function to a bounded, uniformly continuous function on R.

By the above theorem, there exists h 0 >0 such that S h0 f(x) f(x) < e 2: Since f(u)=0 for juj>R, the power series of e x2 converges.

The classical Stone—Weierstrass theorem is generalized in two di-rections. In the first of them, the assumption of compactness of the domain of definition is weakened to countable compactness, and in the second, we waive topological assumptions at all, due to substitution of a topology by a convergence, and thereon the topological continuity by the sequential one. Mathematics Subject. In this thesis we will consider the work began by Weierstrass in 1855 and several generalization of his approximation theorem since.
