Wasn't sure which section to put this q in.
Just reading now that f(x,y) can represent the density of a semicircular wire and so if you take a line integral of some curve C and f(x,y) you can find the mass of the wire... makes sense.
What I don't get is that if I then move the wire around the xy axis it's mass will change. What am I missing?
