Short discussion of Involutes and Evolutes today. I hope we can finish this up and move on to surfaces next week.
Also, my pile of “reworked exam papers” is suspiciously light. I did not get all that I expected today. :( Those need to be turned in Monday at the latest. It is important to me.
Oh, and Jesse and Mark probably want a new curve for the Involute/Evolute project because the arclength reparametrization for the curve I gave them is known to be impossible to compute with elementary functions. Either you can figure out how to maneuver around this (As I think about it, Jesse was on to something. That might work!) or you can try a different curve.
If you pick a different curve, pick a non-planar curve that is not a helix.
