    Calculate div F and curl F for a given vector field

    I was given a bunch of divergence and curl questions in class but I am stumped on this one. If anyone can help explain what I should do with it I would appreciate it.

    Calculate div F and curl F of the vector field F=r^=cosθi+sinθj.


    I understood div and curl for Cartesian coordinates but I don't know what to do here. Again, any help is appreciated.

    Re: Calculate div F and curl F for a given vector field

    Ok, I looked through the link it but I can't figure out a way to apply it to this question... So for this question F=r(hat)=cosθi+sinθj. What you sent me gives me the formula for div F but I don't know where to plug what in in that formula. I may just be stuck on he notation they are using but I still find it difficult. If you could expand on this a bit I would appreciate it.
