Rates of change
About this lesson
This is the penultimate video in this series relating to rates of change for the Year 11 (VCE Units 1 and 2) Mathematical Methods course. This is probably THE most important video in the series as it takes the learning we have already covered and builds the foundation for Differentiation by First Principles. I look at how we can take secants for a number of points on a function, reducing the interval between those two points to gain an approximation for the instantaneous rate of change at a particular point. It might sound rather confusing, but I explain the content in an easy to understand way with lots of worked examples. There is even some humour thrown in too.
I would be grateful if you can support my work by subscribing to my YouTube channel.
