一阶微分形式不变性在课堂教学中的妙用

The Use of the Invariance of the One Order Differential Form in Classroom Instruction

通过举例说明使用一阶微分形式不变性对帮助学生理解凑微分积分法、多元复合函数求导、求多元复合函数的高阶偏导等内容。

Illustrated with examples, the use of the invariance of the one order differential form in the classroom instruction will be helpful to the student＇s understanding of such content as integration by parts, ordinary derivative and higher order partial derivative of the multi-degree composite function and will simplify the problemsolving process.
