both d ∂ symbol work same in differentiation but then why sometimes in text d is used & sometimes ∂

I read that dx is for exact differential and the other one for inexact differentials.

dy/dx is the differentiation of y wrt x, while del y/del x is the partial derivative of y wrt x keeping all other variables constant.

so ∂ is part of multivariable calc & d is a part of single variable calc? am i right? @arcticf0x

But that means that dy/dx is a special case of the other no, and that is not the case.

isnt the curved d used for partial derivatives?

@arcticf0x yeah you are right because I first encountered with ∂ in calc3 (multi) whereas in calc1&2 only used d

I read that a little amount of work must be represented with this \[\partial W\] and not \[dW\] but I still don't get the reasong.

lets say x^22y=2 If you take dy/dx, using implicit differentiation, \[2x2\frac{dy}{dx}=0\] \[\frac{dy}{dx}=x\]  ∂y/∂x,= 2x0=0 ∂y/∂x,= 2x
