Baby calculus vs adult calculus

[joeyGalileoHotto]

Baby calculus: in class
Adult calculus: exam

And that was a ‘simple’ epsilon-delta proof😭

[Qrudi]

It feels like you have to get a phd to understand the epsilon delta definition

[Anjali..]

The most amazing thing was switching of markers

[Luffy_wastaken]

I am just happy cuz I understood what you did and I could do that too if I wanted to.

[SuryaBudimansyah]

One of the things that suck to be an adult

I finally understand this. Delta is a function of epsilon such that an infinitesimal rectangle with epsilon and delta as the legs can contain all points a distance dr away from the point in question. If this rectangle exists than we say the limit exists. This usually fails if for some small length epsilon the delta length is cut short from some singularity that is contained in the small rectangle.

we're literally at the point where we are learning limits

and please don't scare my classmates

[CypherSteve]

That adult calculus thing is way sadder than it looks

[skyfire]

I used to hate epsilon delta proofs. I love them now

[soupisfornoobs]

The epsilon delta definition of the limit is a hell of a lot more intuitive if you first teach kids the definition of the limit of a sequence. That intuition is enough for the form of the epsilon-delta proofs to make sense, but in the war against number theory unfortunately sequences aren't taught in school.

Even adultwr calculus: "given that all polynomials are continuous, we can inmediately substitute in 2 for x in 3x-1, to get the limit as 6-1=5 qed

[Nuss-js]

great and easy showcase on how to find the right epsilons for your proofs.

[AbhimanyuSingh-cgoz]

Is it me or his “ marker switching “ is very smooth

[terryliu]

How did you know that you were going to choose |x-2|?

[mfliebo]

Never seen such a „manly” way to integrate😂

[ekoi]

as a baby, i really thought limits are just another form of functions

[chilli]

Kids do direct substitution, men do Epsilon-delta

[antares]

Gigachad using nonstandard analysis

take any z≈2, let's say 2+epsilon for some arbitrary epsilon - infenitesimal.

Then 3z-1=6+epsilon-1=5+epsilon≈5

Hence the limit is 5
