So how do you think you went?

[you0006]

1 question: for the trig question did it ask for x value or general solution ?

Yeah, 5pi/6 isnt a solution so you'd lose one mark.

Trig question asked for the values of between -pi and pi that would give the solution.

for some reason i also got 5pi/6 how much marks would i lose?

you will lose one mark

Fkn last question screwed me up

bad ... had 20mins to think as well..
thought it was similar triangles and then pythag...
sighs...
then it was something simple
hate my brain

[darkphoenix]

(also must state nature of stationary point and why)

  i didn't do that...

did it even ask for that? ..

I'm 100% sure it didn't. Would be retarded if VCAA penalise people for that...

Why would you need to state the nature when the question already said maximum?

@simon, yeah far out, spent ages trying to figure it out, first ratios, then did something with the volume. Didn't know that i was doing..

How many marks was the find p (probability table thing)
Find a ( apparently 6/125)
Anyone remember?

the p probability was three marks

I think it was 3 for the probability table

Anyone want to post up how to do it? I know that you add all the probabilities up and then make them equal to 1 but I couldn't solve for P from there.

VCAA's excuse (if they penalised) would be that the student needed to show the examiner that the stationary point is a maximum, because if it turned out to be a minimum (it isn't btw) then you'd have to take either end-point\

I think something like this happened in 2007 VCAA exam 2 Q1 extended

[qshyrn]

for the g(x), did we need to write it in function notation, stating the domain???
it was 1 mark so i assumed it was just for the rule .

[jammaj]

Oh fuck! And the 'find a' one 3 aswell? Shiiit

[Linkage1992]

i wrote it in function notation just to be safe. i think just the rule may be acceptable though.

[thushan]

hopefully you didn't have to write the domain

but we don't know how pedantic VCAA might be

for the probability question....
I was soooo dumb not to know how to factorise it - WHY!!!!!!!!!!!!!
If I left it as 16x^2+6p-7=0
would I get 1 of the 3 marks or 2......

why am I sooooo dumb not to factorise it!!!!

[monicapham93]

i think i passed... hopefully
actually managed to get a fair few right!

yeah i got that too, i mustve wasted 3 -5 minutes wondering if i could simplfy that down anymore LOL

yeh same here.. i got 1/2  first but wen i sub it back in the table it somehow didnt work.. i did it again using quadratic formula and i got some weird surd stuff and i just left it at that..
