  • 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
  • What is the difference between $dy$ and $Δy$ and why is $dx$ is same as . . .
    For examples, this $\mathrm {d}y$ as $\delta y$ and $\mathrm {d}x$ as $\delta x$ notation is used in videos like the ones mentioned in a comment by the OP Yashasv Prajapati: blackpenredpen 's “ delta y vs dy (differential) ” and The Math Sorcerer 's “ How to Compute Delta y and the Differential dy ”
  • 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
  • 老师说链式法则里某个 dy dx 不能理解为 dy 除以 dx,为什么?
    \vdots \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。
  • 导数 dy dx 是不是一个整体符号? - 知乎
    更新: 之所以写这个答案,是因为看过很多答案将dx,dy理解成微分,然后来解释微积分符号的含义。这样解释在我看来过于复杂——没有说它们不对,而是复杂。 我之所以不愿意在一元函数阶段引入微分,就是因为我认为,引入「微分」来解释过于复杂: 需要额外定义「微分」到底是什么意思
  • 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 702 被浏览
  • dy dx和dx dy有什么区别? - 知乎
    阅读全文 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
  • calculus - What does dy or dx mean outside the context of a derivative . . .
    What does dy or dx mean outside the context of a derivative or integral? Ask Question Asked 2 years, 8 months ago Modified 2 years, 8 months ago
  • 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?
