Calculate the curl F

  1. Dec 4, 2012 #1
    1. The problem statement, all variables and given/known data

    Calculate the curl F:

    F(x,y,z) = cos(x)i + sin(y)j + exyk at point (1,1,1)

    2. Relevant equations



    3. The attempt at a solution

    After calculating ∇×F, my answer was:

    curl F = 2.72i + 2.72j + 0k

    I'd appreciate a confirmation of my answer.

    No answer is possible until you say at what point you are evaluating the curl. Come on.

    Sorry. Point noted in question.

    Yeah, my over sight. But I'm getting [e,-e,0]. My sorry. Can you check that again?

    Yeah, my answer should be [e,-e,0]. I forgot to put a negative on the second rather than a positive.

    Answer should be:

    curl F = 2.72i - 2.72j + 0k

    or

    curl F = ei - ej + 0k

    Then I'll confirm that.
