    Fake and gay.

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

    • LeFrog@discuss.tchncs.de ⁨3⁩ ⁨weeks⁩ ago

      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

        Electrical engineers are the ones that use j though (because i is used for current)

        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

      The mathematician also used “operative” instead of, uh, something else, and “associative” instead of “commutative”

      source
      • Zagorath@aussie.zone ⁨3⁩ ⁨weeks⁩ ago

        “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.

    source
    • GandalfTheDumb@lemmy.world ⁨3⁩ ⁨weeks⁩ ago

      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.

    • CyanideShotInjection@lemmy.world ⁨3⁩ ⁨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.

        source
    • prex@aussie.zone ⁨3⁩ ⁨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.

      source
    • AlboTheGuy@feddit.nl ⁨3⁩ ⁨weeks⁩ ago

      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.

      source
  • Phoenix3875@lemmy.world ⁨3⁩ ⁨weeks⁩ ago

    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

        source
    • yetAnotherUser@discuss.tchncs.de ⁨3⁩ ⁨weeks⁩ ago

      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) ∆.

    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 ♠ .
