Chebyshev thus approximated functions and he did this in the uniform norm. We already know how approximation in the L2-norm works: this is done using an orthogonal projection, as will be illustrated in chapter 3. This leads to the main question of this thesis: 3.

Chebyshev Polynomials Over a Discrete Set of Points A continuous function over a continuous interval is often replaced by a set of discrete values of the function at discrete points. It can be shown that the Chebyshev polynomials T n(x) are orthogonal over the following discrete set of N+ 1 points x i, equally spaced on , i= 0; ˇ N; 2ˇ N ...

There are several ideas here, some mentioned in the other answers: One: When Gauss was a boy (by the dates found on his notes he was approximately 16) he ...

Ω(n)=logp if n=pm and vanishes otherwise. We define also the following functions, the last two functions are called Chebyshev's functions.

In mathematics, the Chebyshev rational functions are a sequence of functions which are both rational and orthogonal. They are named after Pafnuty Chebyshev. A rational Chebyshev function of degree n is defined as: where Tn(x) is a Chebyshev polynomial of the first kind.

Orthogonality Chebyshev polynomials are orthogonal w.r.t. weight function w(x) = p1 1 x2 Namely, Z 1 21 T n(x)T m(x) p 1 x2 dx= ˆ 0 if m6= n ˇ if n= m for each n 1 (1) Theorem (Roots of Chebyshev polynomials)

In mathematics, the Chebyshev function is either of two related functions. The first Chebyshev function ϑ(x) or θ(x) is given by where denotes the natural logarithm, with the sum extending over all prime numbers p that are less than or equal to x. The second Chebyshev function ψ(x) is defined

The two functions theta(x) and psi(x) defined below are known as the Chebyshev functions. The function theta(x) is defined by theta(x) ...

The Chebyshev polynomials are two sequences of polynomials related to the cosine and sine functions, notated as () and ().They can be defined several equivalent ways; in this article the polynomials are defined by starting with trigonometric functions: . The Chebyshev polynomials of the first kind are given by (⁡) = ⁡ ().Similarly, define the Chebyshev polynomials of the second …

Chebyshev Polynomials - Definition and Properties. The Chebyshev polynomials are a sequence of orthogonal polynomials that are related to De Moivre's formula. They have numerous properties, which make them useful in areas like solving polynomials and …
