摘要
首先通过一个热点问题和两个计算题引出学习格林公式的目的和必要性,迅速抓住学生的兴趣点,从第二型曲线积分入手,通过逐步分析操作给出前提条件,并最终得到公式,打破了书上的传统推导模式.
By a hotspot issue,the purpose and necessity of Green's formula is introduced,which draws the students'interests.By using the second type curve integral and some preconditions,the formula is derived,which is different from the traditional approach as presented in the textbook.
