- 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 . . . - 知乎
帮忙找出链式法则里一处笔误。 关于莱布尼茨记号的历史实在是太长了，有很多数学家的工作在里面，包括Bernoulli兄弟在内的大数学家在后来都对此进行了完善。有兴趣的同学可以去看《古今数学思想》第二册82-92页。

- 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?
- 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, 3 months ago Modified 2 years, 3 months ago
- calculus - Why is the 2nd derivative written as $\frac {\mathrm d^2y . . .
In Leibniz notation, the 2nd derivative is written as $$\dfrac {\mathrm d^2y} {\mathrm dx^2}\ ?$$ Why is the location of the $2$ in different places in the $\mathrm dy \mathrm dx$ terms?
