摘要
介绍了多元函数轮换对称性的定义,给出了轮换对称性应用于多元函数计算偏导数的命题和例子,给出了条件极值求解驻点的简化方法及例子。
First,the definition of multi-function cyclic symmetry was introduced.Then,the propo-sition and examples of applying cyclic symmetry to partial derivatives calculation of nultivariate function were given. Finally, simplified method and examples of conditional extremum for solving stationary points were given.
