CSSA Mathematics Advanced Paper (2 Viewers)

[icecoffee]

1. First function value was 0, (and last was 0)

2. Ditto.

I put the first function value as 0 and something weird and wacky for the last function value! What was i thinking?! *sigh*

I apologise and retract my statement, it just seemed like you KNEW it was the CSSA paper and wanted to cheat.

Look around the BoS resource section and do past HSC papers.

lol thank you, i don't like cheating as much as the next student. You were all talking bout the paper so i wanted to attempt it as practice for my trial (which is independent to the CSSA). I've done all the previous years CSSA trials and scored on average 114/120, highest being 117 and as u were saying this paper was harder i wanted to try it out, sorry for all the misconception everyone lol i'll be more succinct next time

I don't think the CSSA would let the school run the exam later then any other school, and I think they would have a 'make-up'exam for those who missed out on the trials.

yeh find the gradient of the tangent of the 2 points (0,10) and (4,8) and ull get -1/2. therefore f'(4)= -0.5

That's my answer. f(4) is not a stationary point but that's what some people thought, lol.

By the way, what were your guys' answers for bearing question?

 

[dolbinau]

Please read the announcement here relating to trial papers.

Probably a good idea if everyone has a look at it

Isn't this extremely hypocritical considering the resource section is full of photocopied trial papers?

 

[dolbinau]

Btw, when you were finding the area of the triangle in question 2...was the length of one of the sides not an integer? (so the final answer had decimals?)

Guys give up about fucking CSSA shit. They are terrible!

Move on and focus next few exams and then study well for HSC. It will be alot easier than fucking caths!

 

[Zephyrio]

That's my answer. f(4) is not a stationary point but that's what some people thought, lol.

Something like 285degrees.

Something like 285degrees.

wasnt it -0.5?

 

[dolbinau]

he was referring to the bearing question not 10a.

 

[Rix123]

This was by far the hardest exam i have ever written! Not just the questions but the time that they made us do it in. did anyone else skip like a whole question?

And I agree - the first 6 questions took soo much longer to do than other past papers.

 

[doink]

Why does everyone in 2U regular think they do Advanced Maths? Its hardly advanced in any way.

 

[cjordan]

he was referring to the bearing question not 10a.

my bad
was the answer to 10a -0.5 though?

 

[chewy123]

I am not sure with my school used CSSA, does question 10 have a cone in it on CSSA?

 

[homijoe]

my bad
was the answer to 10a -0.5 though?

yeh it was

 

[lyounamu]

Something like 285degrees.

Awesome!! I got that. I was worried that I might get that wrong to lose the hope of 100%.

 

[morning storm]

namu you are too awesome.

That question threw me off for some reason! I know exactly what to do for Simpson's rule and i was pretty confident about the Trapezoidal rule but then i got really confused...
There were six sub-intervals but only 5 function values, what was the first one?
Also for the spiral question it took me a while, a whole heap of crossing out and a lot of scribbling but i finally proved it was a GP! That alone makes me happy, even if i did screw the rest up! >.<

I looked at that question and was like WAAAT?!
Normally when they give you a number of subintervals, you add one and thats the number of funciton values. So theyre giving us 6 and expecting us to have 7 function values?! I just assumed that at 0 and 30 the width of the pond was 0 :S

We were lucky though, our school had taken out all sequence & series & probability so the exam was okay.

Yeah, true. 6 sub-intervals = 7 function values with 5 being heigt. I stupidly used Simpsons' in the first round around. So glad that I chaned during my rechecking.

It was definetly harder than the trials i had practiced. i just went round and round in circles with the trig proving stuff haha i was like so that can equal sin and that one can be cos cos thats sec so its tan upsidedown... etc.
shiit i dont think i got any of the one mark questions either,.. crapppppyyy
