Cerone %J Tamkang Journal of Mathematics %D 2002 %I Tamkang University %R 10.5556/j.tkjm.33.2002.319-334 %X Some generalisations of an Ostrowski Type Inequality in two dimensions for $n-$time differentiable mappings are given. The result is an Integral Inequality with bounded $n-$time derivatives. This is employed to approximate double integrals using one dimensional integrals and function evaluations at the boundary and interior points. %U http://journals.math.tku.edu.tw/index.php/TKJM/article/view/280
