On Gradient, Divergence and Curl

Recently I have been baffled by gradient, divergence, and curl. All of these include partial derivatives. Although I am comfortable with gradient, I am still wondering what divergence and curl are useful for. More importantly, I am still unaware of how their mechanism connects with the partial derivatives. Here I am sharing useful resources on these topics.

I have decided to share the lessons of machine learning by Andrew NG on Vimeo as well. Previously, I uploaded them on Youtube. These are great lectures by Andrew NG. So replicating them on Vimeo also sounded like a great idea.

Machine Learning Lectures By Andrew NG on Youtube

I have been holding the video lectures of the machine learning course by Andrew NG for quite some time in my storage drives. I finally thought about sharing them online. These videos can already be found on quite a few places on the Internet, including YouTube. I have shared them again on Youtube. So it leads to some replication, but it is nonetheless useful. ou can access the whole playlist on YouTube as follows.

Alternatively, you can view the lectures on the following links in a chronological order.
