Switch the divergence coordinate system

  1. Nov 2, 2011 #1
    1. The problem statement, all variables and given/known data
    i have the divergence in the (x,y,z) Cartesian as [tex]\frac{dA_x}{dx}+\frac{dA_y}{dy}+\frac{dA_z}{dz} [/tex]

    and the assignment is to transfer it to cylindrical system [tex](r,{\phi},z)[/tex], by any way i choose.



    2. Relevant equations


    tried with the chain rule, but i am doing something wrong, though
    i get the gradient in the cylindrical system

    It is impossible to tell you what, if anything, you are doing wrong if we cannot see what you did!

    look at 1 then 2

    then there is 1+2

    in the left side there are some derivatives , and variables
    transformation to explain
