The use of equivalent infinitesimal substitution requires certain conditions to be met, and many learners have a limited understanding of the conditions for using equivalent infinitesimal substitution and often misuse it. In response to this issue, this article analyzes the usage conditions of equivalent infinitesimal substitution through the essence of equivalent infinitesimal, enabling learners to fully understand and comprehend the usage conditions of equivalent infinitesimal, understand and master the applications of equivalent infinitesimal, which plays an important role in in-depth learning and application of micro integration knowledge.展开更多
