In the proposed paper a new theorem has been established for the approximation of a function belonging to the Lip(? ) -class by (N, p ,q )(E, s) n n - product summability means of a conjugate series of Fourier series. The result obtained here is a generalization of several known theorems.</Abstract> <AbstractLanguage>English</AbstractLanguage> <Keywords>Degree of approximation, conjugate Fourier series, Lip(? ) - class, (N, p ,q )(E, s) n n - mean, Lebesgue integral.</Keywords> <URLs> <Abstract>https://ijesm.co.in/ubijournal-v1copy/journals/abstract.php?article_id=3422&title=APPROXIMATION OF CONJUGATE FOURIER SERIES OF A FUNCTION BELONGING TO CLASS USING - SUMMABILITY METHOD )</Abstract> </URLs> <References> <ReferencesarticleTitle>References</ReferencesarticleTitle> <ReferencesfirstPage>16</ReferencesfirstPage> <ReferenceslastPage>19</ReferenceslastPage> <References/> </References> </Journal> </Article> </ArticleSet>
