Integral bounds for differentiable functions via monotone derivative constraints and their applications

摘要

This paper develops new integral inequalities that bound the deviation of a differentiable function from its mean using \(L^1\) -bounded first and second derivatives. By leveraging monotonicity properties of these bounding functions, we refine classical Ostrowski-type results to obtain sharper and more general estimates. Several corollaries, including constant-bound cases, are also presented with rigorous proofs based primarily on Taylor expansions and integral inequalities.
