2.7 Find mass of an arc of the logarithmic spiral x(t) = e' cost, y(t) = e' sint, z(t) = e, te [0, 1], if its density p(x, y, z) is inversely proportional to the distance of the point (x, y, z) from the origin (0,0,0).
=lnx for r [√3, √8] if the density equals 2.5 Compute mass of an arc of the curve y = p(x, y) = x².
