Any curve can be considered to be made of sufficiently small straight lines. http://musr.physics.ubc.ca/~jess/hr/skept/Math/node10.html
What is the name of the theorem which states this fact? I know integral calculus sums small units of the curve; but what is the name of the theorem?
I asked the same in mathoverflow but it has been downvoted and got no answer. http://mathoverflow.net/users/9811/zeynel
Thank you
