UwU brat mathematician behavior

Fake and gay.

No way the engineer corrects the mathematician for using j instead of i.

As an engineer I fully agree. Engineers¹ aren't even able to do basic arithmetics. I even cannot count to 10.
¹ Except maybe Electrical engineers. They seem to be quite smart.
- Engineer here, I can definitely count to 10 tho
  0 1 10
- Electrical engineers are the ones that use j though (because i is used for current)
- 10? That’s the name some put to 1e1, right?
- Except maybe Electrical engineers.
  Yup, I can count just fine to the 10th number in a zero-indexed counting system: black, brown, red, orange, yellow, green, blue, violet, gray, white.
- The inner machinations of an electrical engineer is too complicated for me to understand, I think they might be thinking on a higher order to understand these circuits
  Thats why I barely passed my electrical engineering class lol
- Having worked with electrical engineers, some of them are quite smart, the rest have lead poisoning.
How do we know it's gay though? OP could be a girl (male)
- Because it's 4chan. And there are no women on the Internet on 4chan
- Sure OP is a girl. Guy In Real Life
- Newfag.
  (sorry! seemed like the appropriate 4chan reply)
Right? They got that shit backwards. Op is a fraud. i is used in pure math, j is used in engineering.
The mathematician also used "operative" instead of, uh, something else, and "associative" instead of "commutative"
- "operative" instead of, uh, something else
  I think they meant "operand". As in, in the way dy/dx can sometimes be treated as a fraction and dx treated as a value.
My thoughts exactly lol

Wait bottom mathematican is using j=√-1 instead of i and not the engineer? Because I'm EE gang, and all my homies use j.

That part also got me really confused. All the mathematicans I know use i while engineers use i or j depending on the kind of engineer. I've never seen a Pikachu engineer using anything other than j.
- Pikachu engineer
  That's a fucking favorite now. Keeping that in my back pocket.
- OPs boyfriend is obviously an i engineer and hates j engineers. No one can stay angry at mathematicians - engineers on the other hand...
The fun starts when you study quaternions
i^2 = j^2 = k^2 = ijk = −1
- This can't be real
I agree. Clearly i is current. What is this i=√-1 nonsense.
[Lapsed] mechanical engineering gang checking in. I was also surprised. Though, tbh, I think it came down to personal preference of the professor more than field-wide consensus.
a real mathematician would use (0, 1) instead of i

sado-mathochist

Well done, truly
Thado-mathocist. The real chad all along.
It makes me wonder if somewhere out there in a multiverse, a community of lisping incels all collectively draw the chad wojak as as an aramaic looking dude.

NGL, this is hot.

I’m a mechanical engineering student with a math minor and I’m a switch so yeah, I’d take either side of this

Is anyone doing anything tonight?

no, d..do you have a plan?
Something something distance calls for norm, not just squares.
||i||² + ||1||² = 2
Imagining your death. :P
But seriously, it's perfectly sensible when remember that i is just the mathematical representation of "left turn", just like -1 is the mathematical representation of "go backwards"-- and as we know, two left turns sends you backwards. So think about this triangle in the following way:
Imagine you are a snail, starting at the origin. Now imagine that you walk forward 1 step along the horizontal line. Then you turn 90° to the left to start walking along the vertical line, but then, because you need to walk i steps along this line you take another 90° turn to the left, which means that you are now walking backwards and you end up back at the origin. How far away from the origin are you? Zero steps.
This one made me laugh almost as much as the OP. Thank you!

operative?

Also mathematicians use i for imaginary, engineers use j. The story does not add up. I have never seen a single mathematician use j for imaginary.

As an EE, I used both. Def not a mathematician though. Fuck that, I just plug variables into programs now.
- I have both mechanical and electrical backgrounds. MEs like I, EEs prefer j
imaJinary
TIL engineers can't spell for shit.
The associativity thing also doesnt make sense.
Engineer here: mostly use i, but have seen j used plenty. First time I saw j used was by a maths professor.
- Interesting I never saw j from a maths person. Friends (from a decade ago!) in electronics eng dep said they use j because i was reserved for current. perhaps the latter depends on the department.
Cannot confirm, we always used i.

This is the kind of brat I can get behind. 😏

😏

As a physicist I can't understand why would anyone complain about a +jb or $\int dx f(x)$. Probably because we don't fuck

Why would a mathematician use j for imaginary numbers and why would engineer be mad at them?

The only thing I can think of is that the OP studied electrical engineering at some point. But it's a 4chan story so probably fake anyway.
- fake and gay?
I think it might be the wrong way around: Engineers like to use j for imaginary numbers because i is needed for current.
Mathematicians are taught to be elastic with notation, because they tend to be taught many different interpretations of the same theory.
On the other hand engineers use more strict and consistent notation, their classes have a more practical approach.
Using the same notation makes it faster to read and apply math, a more agile approach helps with learning new theories and approaches and with being creative.

I think rather d/dx is the operator. You apply it to an expression to bind free occurrences of x in that expression. For example, dx²/dx is best understood as d/dx (x²). The notation would be clear if you implement calculus in a program.

If not fraction, why fraction shaped?
- If you use exterior calculus notation, with d = exterior derivative, everything makes so much more sense
I just think of the definition of a derivative.
d is just an infinitesimally small delta. So dy/dx is literally just lim (∆ -> 0) ∆y/∆x. which is the same as lim (x_1 -> x_0) [f(x_0) - f(x_1)] / [x_0 - x_1].
Note: ∆ -> 0 isn't standard notation. But writing ∆x -> 0 requires another step of thinking: y = f(x) therefore ∆y = ∆f(x) = f(x + ∆x) - f(x) so you only need ∆x approaching zero. But I prefer thinking d = lim (∆ -> 0) ∆.

I have no idea what they're talking about, but I do love a happy ending.

Relationship goals

$\int dx f(x)$ is standard notation for physicists

Yes but everyone knows physicists like weird notations
But the post says before the integral, so I understand what they did would be $dx \int f(x)$, which is disgusting

They both bottoms.

Hum... I don't think the integral "operator" applies by multiplication.

You can put the dx at the beginning of the integral, but not before it.

Physicists be like: whitness me
- Nobody on your link is treating the integral "operator" as multiplicative.
  dx \int f(x) is blatantly different from \int f(x) dx
If you were using nonstandard analysis with dx an infinitesimal you could put it outside I guess. Maybe with differential forms too?
- Switch it with a summation operator and see if it makes sense. The problem isn't the operation by itself, but the fact that the operator implies an argument application, like a function.
- In the context of differential forms, an integral expression isn't complete without an integral symbol and a differential form to be integrated.

Gods I wish I had a top to troll like this

Imagine a top that isn't math brained, giving you so much more opportunities to troll before they find out...and then when they do learn something you have been trolling them....
- No, in my experience people like that just end up trolling me because they have no frame of reference and don't care about reality. You can't troll somebody with math if they reject the idea of learning anything about or using math.

Physicist behavior

Why are we still visiting literal pro-Nazi websites?

4chan is a largely fascist website but that doesn't mean every single screenshot is fascist or does something to promote it
- It normalizes their behavior instead of shunning it. Remember: If there’s one Nazi at the bar who hasn’t been kicked out, you’re at a Nazi bar.
Didn't realize you had to be a nazi in order to post on 4chan.
- If you are unaware of 4chan being a tool to push people towards fascism, you seriously need to do some more reading and learning. It is an explicit goal of the platform. Here is a random example of an article you can read. Wikipedia is also full of good information.

Thank you for the belly laugh!

so after he angered his bf he got fucked as in trouble with him or sex? raped? wtf lol

Wtf mate, nothing that serious. Anon teased him and the score was settled when they did the thing later that night.
The story looks pretty fake and gay anyway, but it's more wholesome than your idea.
hate fuck:
An act of aggressive sex with someone as if they had no respect for the person as an equal human being, regardless if they actually do, or not. Hate fucking usually entails aggressive, sometimes violent, degrading, and humiliating sexual acts and behaviors perpetrated by an aggressive party onto a submissive, solely in the interest of the aggressor's own pleasure and amusement, and without regard for the submissive party's enjoyment or well being.
Unlike rape, hate fucking is a form of consensual sex where the submissive party has agreed (for whatever reason) to accept the treatment and behavior of the aggressor.
Though unlike proper BDSM, the submissive party has not previously discussed boundaries, likes or dislikes, and doesn't necessarily enjoy all, or even any of the treatment they receive.

My initial thought was that it's surprising that the engineer is using i whereas the mathematician is using j. But I know some engineers who are hardcore in favour of i. No mathematicians who prefer j though. So if such an engineer were dating a mathematician of all people who used j, I could see that being ♠ .

Learned a new word, Hate ****

Anger bang
Hate ****
I too take hate shits on the toilet.
