Homework Help: Grad of a function in vector notation

  1. Jan 17, 2010 #1
    1. The problem statement, all variables and given/known data

    q = xy[tex]^{2}[/tex]z i + y[tex]^{2}[/tex]xz j + e[tex]^{2z}[/tex] k

    2. Relevant equations

    Grad (f) = (fx,fy,fz), where fx, fy, fz are partial derivatives

    3. The attempt at a solution

    I am Comptent at computing the gradient of a function, however i do not see how to do this when in vector notation. Any Help would be greatly appreciated!

    Thank You

    Hi leoflindall! :smile:

    (have a del: ∇ and try using the X2 tag just above the Reply box :wink:)
    We have gradient of scalars, not of vectors.

    Are you sure it isn't .q, the divergence of q ?
