- 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

- 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?
- Integral of $ (d^2y dx^2) dy$ - Mathematics Stack Exchange
I saw this as a step in a calculation and it was confusing The left cancels down to: $$\int \frac {d^2y} {dx^2}dy$$ But surely the answer is $\frac {d^2y} {dx^2}y$; instead, $\frac {d^2} {dx^2}$ is being
