• A NOTE ON THE USE OF PRODUCT MEAN (E, q)B IN THE TRIGONOMETRIC FOURIER APPROXIMATION
Abstract
A. Zygmund introduced trigonometric Fourier approximation where as L. Mcfadden [2] introduced Lipchitz class. Dealing with degree of approximation of conjugate series of a Fourier series Padhy et al. have established some theorems. In this paper, we have extended their result and established a theorem on the use of product mean in the degree of Approximation of the conjugate series of Fourier series of a function of weighted Lipchitz class.
