We establish new inequalities similar to Hardy-Pachpatte-Copsonrsquos type inequalities These results in special cases yield some ofthe recent results
1 Introduction
The classical Hardyrsquos integral inequality is as follows
Theorem A If 119901 gt 1 119891(119909) ge 0 for 0 lt 119909 lt infin and 119865(119909) =

Theorem A was first proved by Hardy [1] in an attemptto give a simple proof of Hilbertrsquos double series theorem (see[2]) One of the best known and interesting generalization ofthe inequality (1) given by Hardy [3] himself can be stated asfollows
Theorem B If 119901 gt 1 119898 = 1 119891(119909) ge 0 for 0 lt 119909 lt infin and119865(119909) is defined by
119865 (119909) = int

Inequalities (1) and (3) which later went by the nameof Hardyrsquos inequalities led to a great many papers dealingwith alternative proofs various generalizations and numer-ous variants and applications in analysis (see [4ndash15]) Inparticular Pachpatte [4] established some generalizations ofHardy inequalities (1) and (3) Very recently Leng and Feng[16] proved some newHardy-type integral inequalities In thepresent paper we establish new inequalities similar to Hardyrsquosintegral inequalities (1) and (3) These results provide somenew estimates to these types of inequalities and in specialcases yield some of the recent results
