I did some assignments related to curve arc length parametrization.
But what I can't seem to find online is a formal definition of it.
I've found procedures and ways to find a curve's equation by arc length parametrization, but I'm still missing a formal definition which I have to write in my assignment.
I saw many links related to the topic
but they all seem too long and don't provide a short, concise definition.
Could anyone help me writing a formal definition of curve arc length parametrization?
