摘要
对无穷小的性质与应用进行了探讨,得到了无穷小在判断级数敛散性、求一些未定型极限问题、运用无穷小的阶来判断广义积分的敛散性以及无穷小在计算含有变上限积分的极限等方面新的处理方法。
Infinitesimal character and its application are discussed and the findings show some approaches of infinitesimal in terms of judgment of convergence and divergence,calculation of undefined limit,judgment of convergence and divergence of improper integral using the order of infinitesimal and calculation of infinitesimal in limit of variable upper limit.
