>>11340714What the fuck are you on about? That's not what he means, obviously.
"Fundamental theorem of calculus" is a heuristic statement which says "when you go around a loop, you accumulate 0." you'd have to be a complete idiot to take this seriously and act like it's some kind of rigorous statement. it's about your intuition for how original fundamental theorem, green's theorem, stokes theorem, divergence theorem, cauchy's theorem for holomorphic functions, etc. are related.
"it literally doesn't make sense." it only doesn't if you associate fundamental theorem with an antiderivative, which you obviously should not.
