Homework Help: Curl from circular density

  1. Apr 30, 2009 #1
    1. The problem statement, all variables and given/known data

    Three small circles, C1, C2, and C3, each with radius 0.1 and centered at the origin are in the xy-, yz-, and xz-planes, respectively. The circles are oriented counterclockwise when viewed from the positive z-, x-, and y-axes, respectively. A vector field, , has circulation around C1 of [tex]0.02\pi[/tex], around C2 of [tex]0.7\pi[/tex], and around C3 of [tex]3\pi[/tex]. Estimate curl at the origin.

    2. Relevant equations

    3. The attempt at a solution

    I know that the circF for C1, C2, C3 is 2, 70, and 300 respectively.. how do I get the curl if I know the circF for each of those
