Abstract We characterize the generalized Gegenbauer polynomials, then we provide a closed form of the the generalized Gegenbauer polynomials using Bernstein basis. We conclude the paper with some results con- cerning integrals of the generalized Gegenbauer and Bernstein basis. Mathematics Subject Classification: Generalized Gegenbauer polynomials, Bernstein basis, Gamma functions 1 Introduction Approximation by polynomials is the oldest and simplest way to represent functions defined over finite domains.
It is possible to approximate any ar- bitrary continuous function by a polynomial and make the error lass than a given accuracy by increasing the degree of the approximating polynomial.
On the other side, polynomials can be represented in many different bases such as the monomial power, Gegenbauer, Bernstein, and Hermite basis form. Every type of polynomial basis has acronis true image for windows server 2003 strength and advantages, and sometimes it has disadvantages. Many problems can be solved and many difficulties can be removed by appropriate choice of the basis. AlQudah 1. We conclude this section with the closed form of the integration of the weighted generalized Gegenbauer with respect to the Bernstein polynomials.
Definition 2. Bernstein polynomials are known  for their analytic and geometric prop- erties, and their basis is known to be optimally stable. Since then a theory of approximation has been developed and many ap- proximation methods have been introduced and analyzed.
The method of least squares approximation accompanied by orthogonal polynomials is one of theses approximation methods. The matrix of the normal gegenbauer polynomials pdf is diagonalized, which simplifies calculations and gives a compact form for the Least-Squares Polynomial coefficients.
See  for more details on Bernstein polynomials and the least squares approximations. AlQudah Theorem 2. The following theorem shows the integration of the weighted generalized Gegenbauer with respect to the Bernstein polynomials. References  M.

The Gegenbauer polynomialsand thus also the LegendreZernike and Chebyshev polynomialsare special cases of the Jacobi polynomials. The Jacobi polynomials are defined via the gegenbauer polynomials pdf function as follows: In this case, the series for the hypergeometric function is finite, therefore one obtains the following equivalent expression:. An equivalent definition is given by Rodrigues' formula: The sum extends over all integer values of s for which the arguments of the factorials are nonnegative.
As defined, they do not have unit norm with respect to the weight. Although it does not yield an orthonormal basis, an alternative normalization is sometimes preferred due to its simplicity:.
Since the Jacobi polynomials can be described in terms of the hypergeometric function, recurrences of the hypergeometric function give equivalent recurrences of the Jacobi polynomials. In particular, Gauss' contiguous relations correspond to the identities. The generating function of the Jacobi polynomials is given by. From Wikipedia, the free encyclopedia.
