Those which are technically not wrong but are still painful to look at are the best imo

[dontsmackdafish]

At my job i have to deal with engineers saying sqrt(-1) = j

[nazeefa]

Whoever wrote the subtitles deserves a medal.

It's hard to feel uncomfortable when you have no clue what you're looking at.

[jackhall]

This video deserves a grammy award for sending the most people to the grave at once

[certifiedpossum]

This video is so specific and appeals to such a specific group of people and i love it

[scottsheffield]

1:33 missed opportunity to make that a definite integral with integral signs as bounds

[HAL-ojjb]

When you try to do math but halfway through the mushrooms kick in

> "Let z ∈ N"

I'm dead.

[treyebillups]

that integral with the integral symbol as the variable almost killed me

[MSE_]

Wow I finally found something that makes people even more uncomfortable than my presence.

"It's rewind time" said no one ever after watching this video.

[LoganCTanner]

These didn't make me cringe, they felt like fun alternate universe hypotheticals to speculate on their meaning

V fun 10/10 ty for video

The expansion of e^i with i as the index and input value made me laugh harder than I probably should’ve

[PoustouPiano]

I'll take a shot at understanding all of the jokes.
0:04 - « F = ma », Newton's second law of motion, except am instead of ma because why not
0:08 - differentiability ⇒ continuity, not the opposite, simple counter example is abs(x)
0:13 - Leibniz's notation for differentiation is d^nx/dt^n, whereas Newton's notation is to add n dots over x. Now we get a pretty cool sword out of this
0:18 - Usually, f is a common letter chosen for a function name, and x for the variable. Here we see the opposite because why not
0:23 - Usually, the element of a set is denoted with the lowercase letter, and the set with the uppercase letter. Here we see the opposite because why not
0:28 - € sign is a pretty common choice to replace the ∈ symbol when you cannot type it easily on your keyboard. Except it's in latex so no excuse
0:33 - Not a right triangle
0:37 - Ah, yes, the negative absolute value
0:43 - It is common to write the two bounds of an integral as a subscript and a superscript. For matrices, a superscript T means to transpose the matrix. Here we see an example of an integral transposition
0:48 - I guess z is a pretty common name for a complex element, not really for the naturals (edit: we usually have n in Z also, now it is the opposite)
0:54 - This one is insane, the arrow over the x should mean it is a vector. And vector as quite often written the same way as combinations. The right hand side of the equation is the combinations formula
0:56 - Not a square (edit : the angular values are switched)
1:02 - Epsilon-delta proof, except epsilon and delta are inverted AND the result is not what we are used to prove
1:07 - Newton's notation adding a second dot to i
1:14 - Expansion of e^x, but using i as both variables for x and n (edit: and congruence instead of equality)
1:18 - I guess Infinity symbol is a correct name for a variable ?
1:23 - True, since pi = 3
1:28 - It is supposed to be g(f(x))
1:34 - I guess integral symbol is a correct name for a variable ?
1:38 - Definition of derivative, using deltas as x and h
1:43 - Expansion of e^x, but x and n are inverted (edit: and congruence instead of equality again)

Here's one: I legitimately knew a Calc student who intentionally wrote her integrals upside down (curls on top left and bottom right). She said her teacher taught her that way.

It hurts man. Blasphemy.

[pierfrancescopeperoni]

This is what every mathematician dreams at night during a bad digestion.

Me who knows nothing about math: I am invincible

[DemonSlayingFootball]

As someone who’s finishing Calculus 3 I’m very impressed that you joked about the Cauchy theorem for functions, that was amazing and it put a smile on my face

[simonefodera]

Today while doing circuit theory exercise I wrote di/dt=ï 😂
