TY - JOUR T1 - Methods SIM&M and M&SIM to Evaluate Double Integrals with Continuous Integrands on the Two Dimensions are not Equal AU - Hilal, Rana Hassan JO - Journal of Engineering and Applied Sciences VL - 13 IS - 10 SP - 3371 EP - 3376 PY - 2018 DA - 2001/08/19 SN - 1816-949x DO - jeasci.2018.3371.3376 UR - https://makhillpublications.co/view-article.php?doi=jeasci.2018.3371.3376 KW - Region KW -integrals KW -dimensions KW -objective KW -subintervals KW -finding AB - The main objective of this study is to derive two new rules numerically for finding the values of the continuous double integrals in region of the integration by using mid-point rule and Simpson’s rule on the x and y dimensions and how to find the correction terms (error formula) and we use Romberg acceleration to improve the results when the number of subintervals of on the two dimensions are not equal.
