Let r = x i + y j + z k and R = |r|. Let F = r/R^p.

find div(F) in terms of r.. i can't figure out how to express it in therms of r

First: express F in terms of x,y,z
Second: Compute the divergence of F by hand
Third: try to identify r in div F

hahaha sweet.. i figured it out. I was thinkin it was just too complicated but when you replace all the stuff with r it works out nicely.

thanks!
