So I've seen quite a variety of notations that deviate from what we've learned in our "normal" math courses.
In math classes we write a volume integral as:
[tex]\iiint_W \rho\, d V[/tex]
but somehow once we start doing E&M and QM, professors often just drop the extra integral signs:
[tex]\int_W \rho\, d V[/tex]
Is this justifiable? Or just a short-hand? I've seen this happen to both volume and surface integrals.
Then there's this stranger notation which is more rarely used:
[tex]\int \frac{1}{|\vec{r}-\vec{r'}|} \, d^3 r'[/tex]
Is there some particular reason why this is used over something simpler [itex]dV'[/itex]?
Maybe I'm just being too picky/OCD about notations, I dunno.
