摘要:Estimations of errors in inequalities related to somequasi-convex functions in literature are simpli¯ed. Two new ge-neral inequalities for functions whose n-th derivatives for anypositive integer n in absolute values are quasi-convex have beenestablished. Some special cases are discussed with applicationsin numerical integration and special means.
