A metal wire is given a ceramic coating to protect it against heat. The machine that applies the coating
does not do so very uniformly.
The wire is in the shape of the curve
The density of the ceramic on the wire is
Use a line integral to calculate the mass of the ceramic on the wire.
∫ f(r,t,ρ) drdtdρ
