math ppl:
my prof said that "for now" fₓᵧ=fᵧₓ. Anybody know what kind of functions these could be unequal for? terms to google would be cool but ELI5 would be even better. I can't even imagine at this point
, any ideas?

the problem is that the partial derivatives might not be continuous and then things can get wacky:

Ok discontinuity is not so wacky*, happens at a point bc of divinding by 0 or whatever. I was worried they were somehow two different functions across the whole domain and it was messing me up inside
I am sure it can get wacky af in some circumstances

Hey there it is! I knew she used a weird word and I was trying to remember so I could google it
"pathological"

mathematicians sure like to use invalidating language sometimes 😔

Wonder how that word ever ended up in mathematics though 🤔 perhaps its a quirk of historical definition?
I see no relation w my folk understanding of it
I've never really paid attention to the language of math, can you think of any other examples of this?

Oh lol it's right there on the wiki. Basically means its poorly-behaved
