Homework Statement
/Homework Equations
[/B]I was looking at Example 5.12 in Griffiths (http://screencast.com/t/gGrZEPBpk0) and I can't manage to work out how to verify that the curl of the vector potential, A, is equal to the magnetic field, B.
I believe my problem lies in confusion about how to apply the equation for curl in cylindrical coordinates (given the final vector potential in equation 5.71).
The Attempt at a Solution
I was unable to make progress while trying to apply the formula for curl in cylindrical coordinates as per https://upload.wikimedia.org/math/1/d/c/1dc228ba3864e64bff1d49fd0984a80f.png
Am I using the wrong equation? If not, how should I be going about doing it? Any assistance is appreciated.
