This video is the first in the series relating to Differentiation for the Year 11 Mathematical Methods (Units 1 and 2 VCE) course. It is one of the most important, foundational videos I think there is in this whole course. It takes time to recap the idea of finding the gradient of a secant before moving onto the idea of differentiation from first principles and limit notation. There are lots of worked examples all explained in an easy to understand way.
