  Final comments

This video is the next in the series relating to differentiation for the Year 11 Mathematical Methods Units 1 and 2 course. Having taken some time to look at how to differentiate from first principles and then how to differentiate a positive power, it makes sense to look at how to differentiate functions with negative powers. I look at what it means to be a negative power and then use differentiation from first principles to show that the "short cut" used for positive powers also works for negative powers! How awesome!!! There are a number of examples which mix the learning from this video with those which have gone before. I use humour and no fuss teaching to make sure that you understand how to smash this section of the course.
