This research paper delves into the exploration of the approximation degree via (E, Q) in the Generalized Lipschitz class A. The study extends its scope to investigate Fourier series product summability means, presenting a comprehensive analysis of the convergence properties within this mathematical framework. Employing rigorous mathematical techniques, the paper provides insights into the approximation capabilities of (E, Q) within the Generalized Lipschitz class, shedding light on the nuances of Fourier series product summability.
