Homework Statement
Consider [tex] f(\vec{x}) = |\vec{x}|^r, [/tex] where [itex] \vec{x} \in ℝ^n [/itex] and [itex] r \in ℝ[/itex].
Find [itex] \vec{∇}f [/itex]
The Attempt at a Solution
I know a vector function maps real numbers to a set of vectors, but here I believe we have the opposite. (inverse of a vector function, assuming inverse exists?)
I am unsure of where to go next.
