Homework Equations
I don't know how to use LaTeX, sorry...
mass = L times integral of density, where the endpoints are the bounds of the region.
However, in this case...it seems to me that things are reserved...
The Attempt at a Solution
I just really don't understand. I thought perhaps I should try and integrate the position function, but...well, that's sort of trivial, and I'm supposed to get an integral in the form of the hint, so that's definitely not the right way to think about it...the density is constant, so I guess I need to break up the cord into little pieces, and integrate that, I guess using parametrization? A line integral??
Sorry for the ridiculous question,
