“…Table 1, compares the obtained results for absolute error with m = 4, 6, 7. We observe from Table 1 that, the absolute errors for presented method are smaller and the numerical solution is more accurate for the same size of m. In Figures 1-3, we present the graphical representation of comparison between exact solution and the numerical solutions obtained by proposed method and the method of [59] for the problem (19) with m = 4, 6, 7 respectively. From these results, we can conclude that m = 4 and m = 6 give larger absolute error, while m = 7 gives smaller absolute error (10 −16 ) and more precise numerical solution.…”
