| Abstract: | A further promotion is made to use equivalent infinitesimal to substitute limit of a function in teaching.the main conclusions obtained can be easily verified that the method of infinitesimal substitution function can be extended to more complex algebra and infinitesimal Ratio and the power function and the upper integral function with varying conditions,expanding the use of equivalent infinitesimal substitution range. |
