P.G. College, Baragaon, Varanasi (INDIA) <p>The present paper deals with a theorem on the degree of approximation to a function belonging to the class Lip (a, p), 0 &lt; a &pound; 1, p &gt; 1 by K^l (E, 1) means of its Fourier series. It extends the result obtained by Tripathi and Prasad¹¹ on the degree approximation to a function f &Icirc; Lip a, 0 &lt; a &pound; 1, by (N, p, q) (E, 1) means of its Fourier series.</p> https://www.ultrascientist.org/paper/1011/ Degree of Approximation to a Function Belonging to the Class Lip
