Work integral on hard field

    given curve:

    vectorian field:

    so the ingral SF*dr (on the curve)
    at the direction of t from 0 to 2pi is?

    if i assign the parametrion to the field i get 12pi from integrals on y and z
    but i still need to proove that the integral there:
    is zero
    and i think its impossible..

    i think using stocks is impossible because building sutaible surface to the curve is imposible

    any other sugestions?
