Thanks for the solutions
With question 9d) do you reckon I could get the marks if I gave the answer as pi-arcos(sqrt6-sqrt2/4)?
Would that be technically giving the answer in terms of pi?

[pi]

You won't get the full 2 marks. So 1 mark depending on your working/ideas.

(and I think i know which mhs kid you are haha xD good luck!)

got 7Pi/12 out of recognition pumped!

[KeeganXD]

Will I lose marks in q1 if I left the modulus symbol in the answer and not include "+c"?

And q2 I made k was an element of R, not Z. Not acceptable?

Other than that, I got everything else correct and hoping for 39/40 if one of the above are accepted.

[Somye]

first one you're fine, because it asked for 'an' anti derivative and that x^2 + 4 is always above zero anyway

Second one unfortunately not, because the general solution does not hold true when n E R
