For the last part of the pyramid question, if i wrote the values of x in degrees, would I lose marks?
Title: Re: Exam 2 .pdf's
Post by: Linkage1992 on November 08, 2010, 07:39:23 pm
I think you might, since the initial domain of x was given in radian.  :(

That was IMO along with Q1, the easiest.

VCAA were really dog this year on drawing on 'assumed knowledge'

All you needed for that Q was Pythagoras and SOHCAHTOA.

And a calculator which didn't skitz it for the last part...

Yeah I had it all the way until it asked for the max volume, and as I'd done with most questions like that, derived it and solved for a stationary point, which didn't seem to work.  Kept throwing 'No Solutions' at me, where as when I graphed it I clearly saw more than 1 solution...

yeh may have ripped multiple choice but i recon im looking at around 65ish/80.

couldnt do last question (-4) or last 3 questions in question 3 (-7) :(
then must account for stupid mistakes haha.
just praying for a V low A+ cut off, which it should be as it was tonnes harder then '07 and that cut off was 63/80
