| 摘 要： | 微积分中提到,二元函数的二阶混合偏导数在连续的条件下与求导次序无关的结论可以推广到二元函数的更高阶混合偏导数.许多教材对这个结论一带而过.学生在学习这部分内容时,理解出现了偏差,本文予以分析,解释,并给出满足条件下的二元函数n阶偏导数的个数确定方法.

| Abstract: | The calculus mentioned:the dual function's second-order mix partial derivative has nothing to do with the derivation order under the continual condition,this conclusion may promote to the dual function higher order mix partial derivative.The most teaching materials do not treat seriously to this conclusion.The student misunderstand when they study this content,this article has analyzed,explained and given the method how to judage the number of the dual function n-order partial derivative under the condition... |
