On Iyengar-type inequalities via quasi-convexity and quasi-concavity
Abstract
In this paper, we obtain some new estimations of Iyengar-type
inequality in which quasi-convex(quasi-concave) functions are involved. These
estimations are improvements of some recently obtained estimations. Some
error estimations for the trapezoidal formula are given. Applications for special
means are also provided.
