摘要
研究了一类代数和求极限中无穷小的等价代换问题,给出相应的计算公式,并举例说明该结论的实用性.
Studied the calculation of some function limit by using the equivalent substitution of infinite small as the algebra sum is infinite small, gave the corresponding calculation formula, and then gave some examples to explain the practicability of the formula.
