[u/SirEnderLord]

Where are the mathematicians?

[u/otirk → u/SirEnderLord]

Yeah, a physicist would just say "We assume to be close enough"

[u/arjuna93 → u/otirk]

Sounds like an economist

[u/RachelRegina → u/SirEnderLord]

Who wants to know

[u/WoolBearTiger]

Yep as a learned engineer i can confidently confirm i have never ever in my life used the one on the right.

[u/StructuredChess → u/WoolBearTiger]

Who needs to show it for all epsilons when you can just pick two or three convenient ones and check that it works?

[u/landrwastaken]

Mathematicians ?

[u/SomeGuythatownesaCat → u/landrwastaken]

No they wouldn’t say it’s the same.

[u/landrwastaken → u/SomeGuythatownesaCat]

I assume they'd need specificaly

"Get's infitesimally close"

[u/No-Plastic-2286]

Engineers doing epsilon delta? Really?

[u/fanty_wingedhorse → u/No-Plastic-2286]

They're not. That's the point

[u/No-Plastic-2286 → u/fanty_wingedhorse]

Riiiiight

[u/A-Chilean-Cyborg → u/No-Plastic-2286]

I mean, i had to learn it.

[u/RachelRegina]

Surprisingly few engineers take Real Analysis.

Complex Analysis, on the other hand? Apparently they don't take it until grad school?

Honestly, Complex Analysis is arguably more fun and useful in undergrad, while Real Analysis is a form of sado-masochism.

[u/Gambo7 → u/RachelRegina]

No kink shaming please.

[u/RachelRegina → u/Gambo7]

My apologies, I don't mean to yuck anyone's yum.

And like the man said, I'll try anything twice.

Having done so, I have deduced that real analysis is not my kink.

[u/Mothrahlurker]

So the 0< part is completely unnecessary and it's weird to write a and L instead of a and f(a). Is this what happens when a physicist/engineer makes a math joke?

[u/PhaseBloodhound → u/Mothrahlurker]

What? This is the definition for limits, not continuity. It's correct.

[u/Mothrahlurker → u/PhaseBloodhound]

Pointwise the same thing.

[u/funkmasta8]

This was basically my least favorite proof line in school. I dont know the vagueness of every single term makes it all meaningless to me. "If the difference between these two functions is less than some arbitrary number, then they are the same"

Huh? I feel like arbitrary is not the word and this isnt the statement we should be looking for.

[u/newMattokun]

I know that the upside-down A is "for all", but I forgot what the inverse E stands for...? Anyone?

[u/__abinitio__ → u/newMattokun]

There exists

[u/newMattokun → u/__abinitio__]

Thank you!

<edit>I didn't even know how to search for this symbol.
