Inequalities for differentiable mappings with application to special means and quadrature formulæ. (English) Zbl 0970.26016

Summary: Improvements are obtained to some recent error estimates of S. S. Dragomir and R. P. Agarwal [Appl. Math. Lett. 11, No. 5, 91-95 (1998; Zbl 0938.26012)] based on convexity, for the trapezoidal formula. Corresponding estimates are established for the midpoint formula. A parallel development is made based on concavity.
