Please see the attached image. It's a part of a study guide for my final, but I didn't put it in the homework section because I already got the answer, I just don't know what it means.

The question has to do with the differential of an arc length. I made some drawings to see if I could make some sense out of it but I don't think I'm quite there.

So when we're talking about the differential of an arc length, what exactly does this mean?
