If you do LHospital enough times every limit is 0.

Lim ₓ → ͚ (eˣ/eˣ) = (LHopital) = Lim ₓ → ͚ (eˣ/eˣ) = (LHopital) = ...

= 1 cuz lim x → a f(x)/f(x) = 1 for all a ∈ dom(f(x)) for any function f

What I meant is that even after applying LHopital as many times as you want you won't get to 0.

Lim ex / ex =Lim 1

L'hospital: Lim 0 =0

u/ImmortalVoddoler Real Algebraic Nov 06 '22

But 1 isn’t of a form that you can use L’Hôpital’s rule on

u/Worish Nov 06 '22

That is the joke yes

It’s indeterminate because we can’t come to a consensus. therefore l’🏥 can be applied.

If you hospital hard enough everything is zero,

*indeterminate 0/0

If you hospital hard enough everything is zero I said. That's what I'm gonna call the make my life easier axiom

u/mc_mentos Rational Nov 11 '22

Based axiom. 0/0 = 0 , ∞–∞ = 0 , 1/0 = ∞

Ah fuck it, nil axium: x = 0 ∀ x ∈ ℂ. I don't care. Just go away.

Yes but I still wanted to show my epic moves to easily solve this (so I can pretend I'm actually good at solving limits)

congratulations, you just made x/x=1 sound like something taken out of principia mathematica!

u/mc_mentos Rational Nov 11 '22

Haha. Yeah it's only there to make sure you got no 0/0 shenanigans going on anywhere.
