If you cut the cylinder vertically, you get a square with side 2pi and the helix is the diagonal.

how formal would you say this playlist(Multivariable Calculus) is ? How rigorous are the proofs compared to textbook such as e.g. Shifrin's Multivariable Mathematics

Your video does a great job of explaining the intuition behind the formula for arclength. The only part I'm confused about is the use of the MVT (6 minute mark). The single variable calulus MVT gives us a t* for each component of the vector valued function r, but would not seem to imply that we have a single t* that works for every component of r. That is, we might have n different t*, one for r1, another for r2, etc. Can you help with this? Thanks for all the work you put into these great videos.
