Evaluation of Double Integral with Continuous Integrands by using Method

Abstract

The aim of this search is to evaluate double integral numerically with continuous integrands .And we choose Trapezoidal method (one of the Newton-Cotes formulas)to use it with respect to the two dimension. (interior x and exterior y).Also we will use Romberg Acceleration to improve the results with respect to accuracy and the number of subintervals that is used it and the time . We will use the symbol RTRT to this method where as R meaning Romberg acceleration and T Trapezoidal method
