Hey guys ive been asked to calculate the divergence and curl of the vector function:
V(x,y,z)= (xi + yj + zk)/r^2
Any help would be great i dont know where to begin with this one!!!
Finding is hackwork much better left for you to do. But once found, you can use symmetry to easily write down:
(just swap x and y around in your answer for ), and
(just swap x and z around in your answer for ).
Of course, you could always recognise that and find div and curl in an appropriate alternative coordinate system ...
PS. I assume you're OK with the level curve question doing the rounds from this assignment .......
