多元复合函数偏导数计算中的几点注意

Some Attention to Calculation of Partial Derivatives of the Multiple Complex Functions

多元函数偏导数的计算问题在各类考试中几乎都会出现,足以说明它在微积分中的重要性。其中抽象的复合函数偏导数的计算又是学习中不好把握的环节,为此提出多元复合函数偏导数计算中的几点注意事项,并举例说明。

The calculation of the partial derivatives of multivariate function almost all kinds of exams will appear,indicating its importance in the calculus.Abstract composite function calculation of the partial derivative is the difficult part of learning,this paper put forward several points to note in the calculation of partial derivatives of multiple complex functions and give examples.
