What do the symbols d dx and dy dx mean? - Mathematics Stack Exchange
Okay this may sound stupid but I need a little help What do $\Large \frac {d} {dx}$ and $\Large \frac {dy} {dx}$ mean? I need a thorough explanation Thanks
dy dx和dx dy有什么区别？ - 知乎
高数变简单 8 人赞同了该回答就是dx和dy谁除以谁的关系呀看完我的这个视频之后还不懂请来怪我~~~ 讲了：dx dy的意思、微分的定义、导数符号的意思视频资源加载失败 dx dy的意思微分的定义导数符号的意思编辑于 2017-12-13 07:20
微分符号，dx，dy到底是什么含义？ - 知乎
微分符号，dx，dy到底是什么含义？刚学高数，用的同济教材，学到隐函数求导的时候，教材莫名奇妙的出现dy，dx ，d dy等符号，此后教材导数全用d什么d什么表示了，教材没有对这些符号进… 显示全部关注者 700 被浏览
In differential calculus, why is dy dx written as d dx ( y)?
In differential calculus, We know that dy dx is the ratio between the change in y and the change in x In other words, the rate of change in y with respect to x Then, why is dy dx written as d dx
高等数学中，dy 的「d」是什么意思？ - 知乎
dx代表一个趋近于0的实数（有时写作h），dy的意义则演化为dx的值乘上导数。另：我看到了目前为止最高赞的答案，d代表Differentiation我觉得是不够准确的，但也只是感觉，如果能注明出处就更好了。
导数 dy dx 是不是一个整体符号？ - 知乎
由于dy dx定义的出发点，这个符号是一个整体，而不是一个可以拆开的东西。微分形式、流形等等概念依然十分重要：之所以定义这些概念，是因为我们想在各种各样千奇百怪的几何上继续愉快地微积分；它们的定义也自然的包含了一元函数的情况——事实上
如何理解dy dx和dx dy的关系? - 知乎
如何理解dy dx和dx dy的关系? 把后者理解为前者的倒数和理解为x对y求导结果在许多情况下是不等的，那么如果我在一个式子里算出dx dy，应该如何分辨它是哪一种情况，是做到下图题目的时… 显示全部关注者 3
老师说链式法则里某个 dy dx 不能理解为 dy 除以 . . . - 知乎
\frac {dy} {dx} = \frac {dy} {df_1}\;\frac {df_1} {df_2}\cdots\frac {df_n} {dx} 这个过程中，我们就可以看成不断地同时“乘”、“除” df_k ，因为每一步的添加项都没有破坏分子是因其自变量改变而产生的无穷小量这一条件。
calculus - Understanding the syntax for derivatives - dy dx . . .
8 I'm new to calculus, and I'm trying to understand the syntax of derivatives: $$\frac {dy} {dx}$$ At a glance it implies some kind of division and some variable "d" has entered the picture Does this reflect some deep relationship between division and derivatives or is it just misleading?
