    This very nice Romanian lady that taught me complex plane calculus made sure to emphasize that e^j*theta was just a notation.

    Then proceeded to just use it as if it was actually eulers number to the j arg. And I still don’t understand why and under what cases I can’t just assume it’s the actual thing.

    Mathematicians will in one breath tell you in one breath they aren’t fractions, then in the next tell you dz/dx = dz/dy * dy/dx

      Have you seen a mathematician claim that? Because there’s entire algebra they created just so it becomes a fraction.

    I found math in physics to have this really fun duality of “these are rigorous rules that must be followed” and “if we make a set of edge case assumptions, we can fit the square peg in the round hole”

    Also I will always treat the derivative operator as a fraction

    Look it is so simple, it just acts on an uncountably infinite dimensional vector space of differentiable functions.

      When a physicist want to impress a mathematician he explains how he tames infinities with renormalization.
