Abs of curl

  1. Feb 4, 2014 #1
    Is correct to affirm that:
    [tex]| \nabla \times \vec{f} | = \nabla \times \vec{f} \cdot \hat{n}[/tex]?


    I asked thinking in this definition:

    Ie, if the affirmation above is correct, so, is correct to express the definition aboce as:
    [tex]\lim_{A \rightarrow 0} \frac{1}{|A|}\oint _{C} \vec{F}\cdot d\vec{r} = |\nabla \times \vec{f} |[/tex]?
