🧵 Serious question

Why is the Leibniz notation in derivatives so widespread? Especially in USA?
Lagrangian notation is superior in every way, if you have a single variable function you don't need to specify what variable you're taking the derivative of you just add a little ' on top of the function value and you're set. And when you have a multivariable function you can just (for example when taking derivative with respect to x of f(x,y)) write f_x(x,y). I have never understood why some people want to write so many fucking words when it can be done much more simply. Is it just to look more smart? I don't get it.

Yeah, I did. Now try a vector field. Oh, wow, how convenient! I now have to write all of my vector field components as dot products with the unit vectors because f_x is already taken.

Clearly you don't.
You are focused on encoding efficiency.
You probably complain about needing to write units in physics.
The d notation is to keep track of "units".

You can mess around with the dx and stuff and move it around and manipulate it algebraically, do substitutions, etc.
It actually means something it's not just a 'notation'.
As the other anon said get into multivariate or differential equations and you'll see.

nigga, subscripts and superscripts are overused already, you want to pile more uses on top?
no thank you.

why?

iirc implicit differentiation becomes painful if you forget that d/dx(y) = d/dy(y) dx/dy and re-deriving that from scratch is easier if you can manipulate the leibnitz notation

How did Lagrange write the following?
(ds)^2 = (dx)^2 + (dy)^2 + (dz)^2

Have fun trying to integrate, retard.
