In 2015, Srivastava and Singh [S. K. Srivastava and U. Singh, Trigonometric approximation of periodic functions belonging to weighted Lipschitz class W(Lp , Ψ(t), β), in: Function Spaces in Analysis, Contemp. Math. 645, American Mathematical Society, Providence (2015), 283-291] determined the order of approximation of periodic functions belonging to W(Lp , Ψ(u), β)-class, which is a weighted version of Lip(ω(u), p)-class with weight function sinβp(y/2) through matrix means of their trigonometric Fourier series. It is a well-known fact that the product summability methods are stronger than the single summability methods, and they can approximate a wider class of functions. Therefore, in this article, an effort is made to determine the degree of approximation for periodic functions from the same weighted Lipschitz class W(Lp, Ψ(u), β), p ≥ 1, using Cδ.T-means of their trigonometric Fourier series.
