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.}, number={4}, journal={Tamkang Journal of Mathematics}, author={Hanna, G. and Dragomir, S.
