      This isn’t a rigorous mathematic proof that would prove that it holds true in every case. You aren’t wrong, but this is a colloquial definition of proof, not a mathematical proof.

        Sorry, I’ve spent too much of my earthly time on reading and writing formal proofs. I’m not gonna write it now, but I will insist that it’s easy

          Oh trust me, I believe you. Especially using modern set theory and not the Principia Mathematica.

      Only works for a smooth curve with a neighbourhood around it. I think you need the transverse regular theorem or something.
