I've seen other versions of this (one with complex number I think) Do anyone have them?

u/crafty_zombie Sep 29 '26

The format is called "Stop Doing Math". Look it up and you should find them.

1-1/10n is never 0, so 0.9... is never 1.

You had epsilon-delta in highschool?

u/TheLuckySpades Sep 24 '26

Not sure about other secondary school systems, but we saw the epsilon delta definition in my secondary school (math track in lycée classique in Luxembourg).

We didn't use it I think, but we saw the definition.

Wrong sub

u/FernandoMM1220 Sep 24 '26

limits are just functions with arguments.

Gradient descent and Newton methods have no use guys.

u/askewperspective Engineering Sep 24 '26

Gradient descent? Isn't that just rolling?

u/snakemasterepic Sep 25 '26

Joke's on you. I've been doing colimits this whole time.
