What is the divergence?

Показать описание
A basic introduction to the divergence of a vector field - one of the basic operations of vector calculus. I discuss how to calculate the divergence and its physical connection with flux density. Plenty of examples are discussed.

Hi - at some stage I will release the notes, but in the meantime there is a section on curl in my new (free) ebook. The download link is in the description.

Where is your ebook? The link doesn't work any more.

Sorry, I meant "divergence" (not "curl")

One of the many things that has always confused the hell out of me with this subject is that if M is a function of x AND y, and N is a function of both x AND y, then why are there no dM/dy or dN/dx terms in the div F equation?
