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.

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…

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.

Engineer here: mostly use i, but have seen j used plenty. First time I saw j used was by a maths professor.
iAvicenna@lemmy.world 5 weeks ago
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.

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
Phoenix3875@lemmy.world 1 month ago
I think rather
d/dxis the operator. You apply it to an expression to bind free occurrences ofxin that expression. For example,dx²/dxis best understood asd/dx (x²). The notation would be clear if you implement calculus in a program.bhamlin@lemmy.world 5 weeks ago
If not fraction, why fraction shaped?
Amir@lemmy.ml 5 weeks ago
If you use exterior calculus notation, with d = exterior derivative, everything makes so much more sense
yetAnotherUser@discuss.tchncs.de 5 weeks ago
I just think of the definition of a derivative.
dis just an infinitesimally small delta. Sody/dxis literally justlim (∆ -> 0) ∆y/∆x. which is the same aslim (x_1 -> x_0) [f(x_0) - f(x_1)] / [x_0 - x_1].Note:
∆ -> 0isn’t standard notation. But writing∆x -> 0requires another step of thinking:y = f(x)therefore∆y = ∆f(x) = f(x + ∆x) - f(x)so you only need∆xapproaching zero. But I prefer thinkingd = lim (∆ -> 0) ∆.

Why would a mathematician use j for imaginary numbers and why would engineer be mad at them?
CyanideShotInjection@lemmy.world 5 weeks ago
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.
dandelion@lemmy.blahaj.zone 5 weeks ago
fake and gay?
prex@aussie.zone 5 weeks ago
I think it might be the wrong way around: Engineers like to use j for imaginary numbers because i is needed for current.

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.

Thank you for the belly laugh!
jsomae@lemmy.ml 5 weeks ago
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 ♠ .

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
gnutrino@programming.dev 1 month ago
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?

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

That’s hilarious. You’re not seeing what’s going on backwards just like that (as I point at the point going nowhere shitty) in an equation that is finding as many clAEver ways to say something you actually not caring about talking about.

The mathematician also used “operative” instead of, uh, something else, and “associative” instead of “commutative”
Zagorath@aussie.zone 5 weeks ago
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.
