Approximation of a Function Belonging to Lip ((α, r) Class by Np,q. C1 Summability Method of its Fourier Series

In this paper, an estimate for the degree of approximation of a function belonging to Lip (α, r ) class by product summability method N p.q .C 1 of its Fourier series has been established.
