CSSA Maths Trial!! (1 Viewer)

???
with question i think ur referring 2, did u get something lyk $118,000??

i honestly dont remember.. but to answer your (2,16) question.. i kept getting like 3 or something as the x value n that was the 1mk i didnt end up having an answer for.. shows what no study does! frustrated me grrr

lolz np buddy

did any1 get the point p(2,16) in question 5 part (c) i think it was
it was where they gave you the equation y = 2x^3 and y = 20 - 2x and the point (10,0)...

I subsititued both equations into each other.

2x^3=20-2x

2x^3 +2 x -20=0

2(x^3 + x - 10)= 0

Then i fudged it. (made 2 be an x intercept)

And then i sub'ed 2 into equation to get 16.

Fuck i should have subsitued the numbers. I didn't realise they were getting you to fidn the point of interception but prove (2,16) was a point of interception. FUCK. I got the second part though(finding area between curves)

^^^
yeah i waas doing the same!! i was like wtf this is aint right!
so i just subbed it into the 2 eqns

 

[Ahmed A]

yeah i was doing the same thing also.
But then i remembered that you cant equate a cubic equation to another equation or something like that.
so i subbed two into each equation and got it. Then walked out of the exam room thinking i got it wrong. Phew

 

[kokodamonkey]

oh you gotta be fricken kidding me. i spent like 30min trying to solve a few of those and didnt think to just "sub it in" i thought that was like "cheating" and doesnt count. hmm stupid reading questions wrongly. bye bye 1mark :<

OOOOOOMG yes that maths trial was sooooooooooooooo horrible!!!
i reallly didnt like it! and of course it happens to have a massive weighting towards our hsc mark! FABULOUS!

IS IT JUST ME OR IS IT GETTING HARDER AND HARDER TOO KEEP MOTIVATED TO STUDY!!??? i sit down to study but find it soo easy to get distracted! my room has never been so tidy!!

 

[doink]

2u maths paper was the easiest thing i have ever done. Completed in 1 hour 50 minutes. 3u paper could of been better.

 

[Beccstar]

why would u come to this forum and say that!!!!!!!!!
thats mean! go away!

SHIT SHIT SHIT!! i forgot to do that!! o fudgen hell lol i thot factorising and than im like x to the cube? wth u suppose to do that? XD

 

[craig123]

haha wasnt as easy as that, the similair triangle didnt form ny ofthe alternate angles or cointerior

 

[smallpat]

it was easy i thought, q10 was shit easy, q6 was the hardest i reken, that AP GP i didnt realise to add both up individually so i made a table fo values, counted up to 67 million.
Finished with about 45 minutes to spare
wat about everyone else??

 

[smallpat]

you had to use trig

HAHAHAHAH. good approach. best approach ever!

 

[gotheswanz]

lol yeah i did the same thing. only hard question in the whole test. i mean how can we have rain drop in the 1st minute and then after 25 minutes we are getting 33 million rain drops a second. now that is some storm. haha anyway i just added up all the values as well... didnt even fit on my calculator, there were too many numbers but it was like 67 million and sumthing weird

 

[bassguy]

My one must have been changed a lot - it said it was based on the CSSA trial, but I don't recognise this stuff.
Was pretty easy though, finished with about 45 minutes free.

 

[xoxo]

well im fairly confident i passed
as trials are supposed to be harder and than hsc i think the hsc should be a good paper in terms on hardness. i found it also very similar to past CSSA papers and overall i didnt think there were any surprises as such. nothing really very out of the ordinary. some parts were hard i will admit but meh it will be interesting to see what i get i guess...screw 3u though

 

[psi-4u]

my friends that do extension found it easy but that was probably one of the hardest test's i've done

 

[kokodamonkey]

i do not remember the rain drop question..

 

[Ahmed A]

i do not remember the rain drop question..

+1
lmaoo
which rain drop question?
it sounds really sad, maybe that's why i don't remember it...

 

[kokodamonkey]

are we sure the rain drop ppl are talking about the cssa trial???
