# Curl of the vector potential

## Homework Statement

For some reason I can't find anywhere online that gives a good example of the curl of a vector function in spherical coordinates. I need to compute ∇ X A where

A = $\frac{ksinθ}{r^{2}}$$\widehat{ϕ}$

If anyone can point me in the right direction of a good video or text tutorial that shows the curl of a vector potential in spherical coordinates I would really appreciate it. Thanks.

## Homework Equations

I know how the curl is set up in spherical coordinates from my text book I'm just not one hundred percent sure how to go about it.
