May 2, 2015 · 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.

Jul 31, 2020 · 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: …

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...

\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 …

Jul 25, 2019 · Yes, ∫dy is somehow the same as y! imagine dy as a bit of y and ∫ as a sum over the bits.

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 …

Dec 2, 2019 · I've read 'similar' threads here, that ended up as long fights about 'dy/dx' being or not being a ratio, so I'm clearly not the first person to wonder about what it is.

Sorry for reviving this, but how does this work if y is a constant, for example, y = 10. dy/dy = d (10)/dy. So 1= 0? that doesn't make sense

Mar 5, 2011 · 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?
