Free MIT Courses on Calculus: The Key to Understanding Deep Learning - KDnuggets

It is difficult, perhaps, to link this to neural networks, but the basic intuition of calculus is achieved. If you are looking for a more full treatment of this branch of mathematics, you will want to seek out some more robust learning tools. Here are 3 courses and a textbook to help out, all from MIT's Open Courseware initiative, which will cover everything you need to know about calculus to understand deep learning -- and far beyond.
