The 'whole of the topic in … minutes' videos DO NOT comprehensively cover everything you need to know for your exams. It would be impossible to include 2 years of teaching in 1 hour. These should NOT be your only source of revision • Do the 'whole topic in... My exam predictions are just GUESSES!! I don't have any insider knowledge just years of looking at exam papers.
Disclaimer; You should not carry out any of these practical’s without carrying out a full risk assessment of your own first.
I am human, and I make mistakes, please point out any that you find and there is no need to follow that with a load of abuse.

hi ive just finished year 11 and i want to be ready for alevel maths, how comes you take away 1 from the power at the beginning?
also why do you get rid of the +h at the end
and why is there an x^2 on the y axis
The explanation of n (for non zero n) to the power of 0 equals 1 is not very good at all. I think there are 2 better ways of doing it
1. Add a "1 times" in front - so 2 squared is 1 x 2 x 2 and so on. There for anything to the power 0 is 1
2. An earlier video already talks about indices, use that to show anything to power 0 is 1
A further note, the explanation for the differentiation rule is more confusing than necessary. Best start with
1. -- f(ax) = a*f(x)
2. -- f'(ax) = a*f'(x)
From this, the rule (in this video) becomes much clearer.
