This is bullshit, it defined but didn't even use the continuous functions πŸ‡and 🍍.

golang is gonna be fuckin pissed when it finds out

Those are backups in case the other functions break down.

🍊 isnt a metric dumbass, its an orange

But what if it was grown in Europe?

[–] [email protected] 4 points 5 days ago (1 children)

So to clarify, definitely European and not African?

I don't know falls to his death

Americans will use anything other than metric

Its probably reasonable to say that 25% of math majors cant solve this, therefore non-math majors aren't people

"sup" without a "\" belongs-to-set symbol \[ and \]

[–] [email protected] 25 points 5 days ago

I mean, technically, it is true. At least 25% of people can't solve that.

[–] [email protected] 19 points 5 days ago

Yes I can, as this is just the metric induces by the L-infinty norm. But why did we introduce πŸ‡ and🍍?

[–] [email protected] 21 points 5 days ago (1 children)

I can answer the question. No.

[–] [email protected] 6 points 5 days ago

He’s right.

Look at this shmuck, using the supremum of a continuous function on a closed interval when it clearly achieves a maximum. I bet they’ll feel real embarrassed about that one when they’re falling asleep years from now.

[–] [email protected] 6 points 5 days ago (1 children)

Christ, it's like people just don't even give a fuck about the extreme value theorem anymore?

[–] [email protected] 3 points 5 days ago

I get you are joking, but I've seen many literature just using sup for maximum. Maybe for consistency or laziness, idk why

[–] [email protected] 8 points 5 days ago (1 children)

I am waiting for someone to actually answer this

Thanks. I've mostly forgotten real analysis by this point but the meme seemed really familiar, lol.

[–] [email protected] 1 points 5 days ago

Thanks for the link. I expected there would be a problem with triangle inequality but didn't want to do the actual proving πŸ˜…

[–] [email protected] 1 points 5 days ago

Oh, I expected it to be some unsolved problem.

By using 🍊 to rate how good this post is(out of 5), i made it a metric for how good this post is

The function is a homeomorphism on R, so it preserves its topological features.
