my fault. when i said d(theta) and d(phi) were unit vectors i mean a(theta), a(phi).

Find the expression for the unit vector tangential to the curve given in spherical coordinates by r = 1, \phi = 2\theta, 0 \leq \theta \leq \pi the equation for the differential length vector for spherical coordinates: dl = drar + rd\thetaa\theta + rsin(\theta)d\phia\phi where ar, a\theta, and...
