In this video I continue with my tutorials which cover the necessary vector calculus for classical electromagnetism which is pitched at university undergraduate level. Specifically in this video I discuss the divergence of a vector field. This mathematical construct is used both because it has a very interesting physical interpretation and that it simplifies complicated mathematical expressions.
This video tutorial series covers a range of vector calculus topics such as grad, div, curl, the fundamental theorems, integration by parts, the Dirac Delta Function, the Helmholtz Theorem, spherical polar co-ordinates etc.
Thank you for watching and I hope that this matches your requirements. Please feel free to provide feedback via comments and share with your friends.
