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
- 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
  
  Newremoved.
  (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

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!

Me, a language/arts person: "Huh?"
- Web dev here. "Huh?"
- Medical here. "Huh?"

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
- As a software dude I can see you wrote a regex, I just can't find out what you're trying to match.
  
  Pardon my denseness, but is this sarcasm? Since that is a TeX snippet.
  Why would a RegEx start with a $?
  
  Heeyy... So when you need to express something more, well, delicate than just code, you need to use math symbols. For that you can use tex expressions. Modern markdown supports it: just copy and paste the $..$ part into any render engine

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.

Relationship goals

They both bottoms.

Better plot than 50 Shades of Grey
- hehe plot. getit? math and graphs and shit
  
  Lmfao kill yourself

I believe the correct terminology is denominator mathematician.

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

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.

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

Physicist behavior

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.

Thank you for the belly laugh!

But physicists actually do that? They often write it like this: ∫ dx f(x) or this: ∫∫∫ dxdydz f(x,y,z)

Can somebody ELI5 this for my troglodyte writer brain?

Why are we still visiting literal pro-Nazi websites?
- 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.
- 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.
