Homework Help: Convert 3d cartesian to polar

  1. Apr 20, 2009 #1
    1. The problem statement, all variables and given/known data

    I need to convert this to a polar coordinate
    [tex] \vec{F} = 5xz\vec{i} + 5yz\vec{j} + 4z^3\vec{k} [/tex]

    2. Relevant equations

    3. The attempt at a solution

    I have no idea to do this, can someone help?

    First, you have to write the equations that express x, y and z in terms of θ, φ and r. Then you write i, j and k in terms of the unit vectors [itex] e_\theta, e_\phi[/itex] and [itex] e_r [/itex]. Then you just substitute.
