(1) the design of algorithms and programming, for debugging. (2) with good debugging procedures for the settlement of the following questions: the calculation of the approximation, for the steps to check the accuracy of a first function of the preparation of the calculation procedure step II, the implementation of the preparation of good Romberg algorithm, the output T. (3) using Romberg algorithm and composite Simpson formula for calculating the approximation, respectively, of which b respectively for b = 0.1, 0.3, 0.5, 0.7, 0.9
