This video looks at the three different types of stationary points needed for the Year 11 and Year 12 Mathematical Methods course. I recap the work from a previous video but add more depth and show how to use the CAS to effectively find not only where the stationary points are, but how we can find the nature of each of the points. I show how to test either side of a stationary point as well how to use the double differential. There are a couple of worked examples which I use to scaffold the theory.
