Differential Geometry

I just spend a while trying to figure out what div(fii) is using the definition of div that says d(iXdV)=div(X)dV. In the end I just got div(fii)=∂ifi. I was also reminded today that the definition of df is that df(X)=Xf. I swear all differential geometry amounts to is swapping characters around.
