It certainly wasn't a 4u question! Just differentiation and algebraic manipulation. See my solutions here.Originally posted by saladsugery
actually it was all pretty ok except for 10b) :mad1: ... i may get 3 marks there if i'm lucky. if it is a 4u question, then with any luck they won't count it. can anyone except sourie confirm/deny this? perhaps an admin?
You used circle geometry? Hmm. You didn't need to - there was a big isosceles triangle there (sides are radii of the circle). If you drop a perpendicular down from the apex of the triangle to the base, it's going to divide the base in two (not something you need to prove, because it's an isosceles triangle). Then it's just simple trigonometry.Originally posted by saladsurgery
also, a question to people who don't do 3u:
how did you do the first "pizza" question in 10a) without using circle geometry (i.e. a radius perpendicular to a chord bisects the chord) to get the side length = 10
You seem to be contradicting yourself yet again. OK here you say that because some ppl thought it was easy they will fail. BUT in the ancient and business exams you said that it was so easy that you left half way through. So I think we can say that youre going to fail as well. Oh hang on, Im sorry I forget.......thats right you are an absolute genius so this little theory of yours doent apply to you.Originally posted by Sourie
goddam....we'll see what happens when you idiots get your reslts and wonder why your viewing the question as an easy one was your downfall!!

Well since youve been attacking everyone for their names, what the hell kind of a name is 'stop booting me'? Just going around with a name like that is advertising your unpopularity to everyone.
Oh, so you're different in the real world aye? Hard to believe...Originally posted by Stop Booting Me

mannnnndy, i dont give a shit here ok...its not for fucken socialising.......you must actually step away from your damn computer to do that ok.....hiding behind some screen doesnt count as being social and the people on here arent your damn friends!!
now i do take into account that you may be unlucky in some regards due to your appearance but styaing here for the rest of your life will never help your situation!
LOL! How'd you manage to pull that off?Originally posted by Sourie
Anyway i dont care coz i didnt study and lets just say i had a little extra help from mr 'infrontofme'....hahah no one even had a clue!!
LOL! Yup! And considering that I didn't even attempt Q10, you can decide for yourself which category I belong toOriginally posted by ezza
i heard that question 10 is usually what seperates the less smart students from the smarter students...
