分享兴趣、传播快乐、增长见闻、留下美好，大家好，这里是LearningYard学苑，今天小编为大家带来文章：用mathematica求偏导
Share interest, spread happiness, increase knowledge, and stay good. Hello, everyone. This is LearningYard Academy. Today I will bring you an article: Using mathematica to ask for partial guidance
大家下午好呀
上一次给大家介绍了用Mathematica作三维图的方法
附上补课链接
今天小编分享的也是Mathematica哦
老规矩，感兴趣的小伙伴赶紧@你的小伙伴一起学习吧！
Good afternoon everyone
Last time, I introduced you to the method of using Mathematica to make 3D graphs.
Attach a link to make-up lessons
Today the editor is sharing Mathematica too
Old rules, interested friends, hurry up @you friends to learn together!
接下来开始今天的教程学习：用Mathematica求偏导数与多元函数的极值
（有条件的同学建议先复习一下大学课程微积分里的相关内容）
Next, start today’s tutorial study: Use Mathematica to find the extreme value of partial derivatives and multivariate functions
(Students with conditions suggest to review the relevant content in the college course calculus first)
注：在Mathematica中，还是有些微分函数用于直接计算的，如下表所示
Note: In Mathematica, there are still some differential functions used for direct calculation, as shown in the following table
