- 2. On the theorem of infinitesimal and infinitesimal For example, theorem: the sum of finite infinitesimals is also infinitesimal Suppose that when x tends to x0, it is proved in the book that the sum of two infinitesimals when x tends to x0 satisfies the condition of infinitesimal But I think, why do two infinitesimals just tend to x0 when proving? The theorem says that two infinitesimals do not necessarily have the same x0? For example, the x power of (0.5) and the x power of 2 are infinitesimal. Although these two functions are not infinitesimal when they tend to finite values, their sum will not be infinitesimal Why?

On the replacement of equivalent infinitesimal There is a saying in the book: when calculating the limit of the ratio of two infinitesimals, the product factor of the numerator or denominator can be replaced by its equivalent infinitesimal. First, what is the product factor? For example: limx → 0 (e ^ AX-1 + e ^ BX-1) / 2x, can the numerator replace ax BX? It seems that this is not the product factor
