On number 3 . It would be 4/25 after expanding instead of 2/25. Any way is great video . Thank you

For question 1, would we be expected to simplify the answer, by factoring out the 1/9 from the inside, splitting the surds then square root the 1/9, similar to how we did it with hyperbolic functions?

What would you say is the hardest topic within the A level maths spec and A level further maths spec?

how would you do 6 implicitly ? I never understand what to do when there's a constant in front of the inverse trig

Interesting I'm still only on single maths (doing further next year) but I've already learnt to differentiate the inverse trig functions for fun. Would normal maths students be expected to be able to integrate arctan, arccos, arcsin etc as well? I had a go at those and they didn't seem beyond normal maths imo.
