nah he got it right

are you first internally?

it can rain on 0 days

i showed that f(pi/6) > f(pi/3) and f(pi/6) > f(0) so there must be a max between 0 & pi/3 then showed there was 1 stationary point in that domain, therefore a max

that's not really what he was asking...

i thought you were implying raw mark rather than aligned mark at the start. either way still better in 3U!

Re: hmmm. carrot said i won't so i think i got 100%

laughed at this

for that question, i showed distance QS = a, not quite as elegant as braintic's solution but it worked

100% then. satisfied with HSC now

not at all tbh just the one question that everyone did by implicit differentiation but it wasn't hard without

they leave final HSC marks to 1 decimal place, then in the event of a tie they look at 4U marks

nah because i didn't say y =/= 0 so it's not quite the same thing, it's like half the restriction

Re: hmmm. unsure about whether i'll lose a mark for missing units in 12.a.ii but otherwise it's looking good

Re: hmmm. no because it's only max for pi/8 using other methods

other than that everything looks good i think. would i lose a mark for not writing the units in 12a)ii) ? and in part 13ciii (parametrics), i only stated that y =/= 2a, i didn't say x =/= 0. would i lose a mark for this?

11.f should be +1 not -1 edit: the product rule at the start is wrong is all, error carried through :)

q11e should be strict inequality edit: somebody already corrected this

Re: hmmm. i actually circled them in my booklet and put the units in for part i

i was about to ask this
