    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.

      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.

      As an EE, I used both. Def not a mathematician though. Fuck that, I just plug variables into programs now.
