Sketch the vector function
and compute its divergence. The answer may surprise you...can you explain it?
The Attempt at a Solution
I have recently started with Introduction to Electrodynamics by David J Griffiths and according to the book notation,
I have calculated the divergence to be zero. The problem is how do I draw the vector function? I mean the book shows a few drawings of vector functions but they all are in 2-D. I have three variables, x,y and z. How do I sketch the function in this case?
And what is special about the result?
Any help is appreciated. Thanks!
