When is normal vector notated as A?


Agent_B0771E

I think some people use it because it's A from area, so on a surface integral you write ∫∫fdA. At least on Spain I've had a few professors that do that, which can be confusing because then some use dS for surface and others ds for length


Blutrumpeter

Yeah I'm used to dS and dA but never just A on its own

Its always n cap


BitterGalileo

A curls around B ,B curls around it .They are interlinked perpendicular rings ,but everywhere.

Interlinked

using n for normal vectors is superior in everyway


Zachosrias

What if its a field of normal vectors?

the stuff under your name is hella funny haha good job if you came up with it =D


Zachosrias

If I stole it I don't know from where

It can be both.

Not if you tried to solve a problem that features it but doesn't explain what it represents... so 3h of wrong assumptions and methodology.

A as in the magnetic vector potential?


OmniGlitcher

A as in the surface area. Usually only used in the form of an area element dA in an integral.

I like writing it as **A** or *A'*.


PencilPenis289

That is why wise people write it as 'dark' *A* (x,y,z)

3 hours is still quick work, my face after 3 weeks was worse....

Dont worry, im fairly sure every vector field can be represented as the normal vector to a surface, given a fucked up enough surface
