This paper introduces a new function to calculate definite integral approximation and elaborates on the advantages of the inte- gration calculation method and calculation process; quantitative numerical calculation shows that the method can obtain a high accuracy. In other words, by means of computing, the approximation of the integral is almost easily converted to the exact value, so it provides new scientific basis for engineering design in such integral approximation.
