Find a pair of fields having equal and divergences in some region, having the same values on the boundary of that region, and yet having different curls.
I really have no idea on where to start for this.
Would making up 2 arbitrary fields in spherical co-ordinates work?
a(theta) + b[tex]\phi[/tex] + r[tex]\hat{r}[/tex]
d(theta) + e[tex]\phi[/tex] + f[tex]\hat{r}[/tex] (where [tex]\phi[/tex] and (theta) are unit vectors, latex isn't working for me >.<)
Then trying to solve for the conditions mentioned?
I know that r[tex]\phi[/tex] and r2[tex]\phi[/tex] work on the sphere r=1 but I have no idea to go about deriving this. I think this has more to do with me not really grasping vector calculus. Any hints,tips,pointers greatly appreciated.
