[SOLVED] Divergence, nabla
1. Homework Statement
Given the vector, find the dot product.
2. Homework Equations
dot product of nabla and the vector is just partial derivative of each component.
3. The Attempt at a Solution
I'm trying to figure out if I can just leave out the denominator, since it is a scalar (the magnitude of vector r). The answer, however, is 2/r , so I'm starting to think it's gonna be necessary to change to plane polar coordinates.
