The 2004 HSC - Mathematics Extension 1 Paper (4 Viewers)

[BlindGuardian]

all u ppl that think that was easy....u must be stoned.......do u guys friggin speak maths at home or something?

 

[townie]

i realise the paper has been posted, but i thought i would also post it as a single PDF file as well for convenience.

Enjoy

ok first of all it was a pretty hard paper, not in content, but in the time allocated.
like im lookin at 80% if i did no stupid mistakes. al u ppl who say u got 83/84 be happy....u guys shit me...gettin 95+ % is not a screw up.
like fuk i was gettin at least 85% in past papes, n this one i dunno
hopefully i get my 80%, coz i didnt go dat well in 4 unit. ( maybe 65% max)

 

[Shuter]

Most of the people saying it was relatively easy do 4U maths (myself included).

And yes, someone please post the time for SHM part 3, I really want to know if I guessed correctly.

wrote the wrong question in wrong booklet, spent like 5min re writing it bahhhhh

same hear after q4 i kept doin q5 in da same booklet.
had to rewrite it out.

 

[becany]

Hmm...i dunno if im right, but for the harbour entrance, the time it is 2m above low tide is 4.28...but then i read the question wrong so i got the answer wrong..bleh someone (ie the ones who are like ooo i got 83/84), whats the answer?

 

[greekt0y]

liek wot did evry1 get as the locus??? i got y=-4a, but now im thinkin it mite b y=-a

 

[donis]

um, to those randoms who are pissed off with a mark of over 80+/84 - get a life I'd say. Anything above 80/84 is good, but you people are fools. yer hsc! yer wd cockey people!

 

[nit]

Time was 4:28 am

Me, I'm hoping for 83/84...didn't include the second solution to the tantheta question in 6...I hope i get a mark for that. Apart from that, I'm fairly confident of not having committed any sillies...

 

[Teleph]

Sign....I had no clue how to do Q7 part B ....so guess i'll get somewhere around 70-75/84

To those who rkn the test was easy....get a life....most F ed up 3u paper i've ever done

 

[Managore]

I've failed.. so badly.. I hope I got over 1/3 of them right actually, then I'll be moderately lucky... that was the worst exam, of my life. I had a fucking headache and a cold I was trying to hold in.

Worst
Exam
Ever

 

[Managore]

I HATE binomial theorem, SHM and projectiles so there goes nearly 1/3 of the marks anyway... the test was so stupid, where the hell was the hard probability, inverse, graph sketching, harder integration etc etc etc etc etc??

 

[Lazarus]

Most of the people saying it was relatively easy do 4U maths (myself included).

You're lucky! That means better scaling for 4U.

The scaling parameters for Extension 2 are determined by the performance of the Extension 2 students on the Extension 1 paper. (And the scaling for Extension 1 is determined by the performance of the Extension 1 students on the Mathematics paper - the same scaling is then applied to Extension 2 students for their Extension 1 component.)

wot did u st00ges get for the locus?????

 

[Supra]

hte SHM q in this test was very easy, we were very lucky htey didnt ask one harder than we got...

 

[chriscity1]

I thought the questions weren't hard - but we so didn't have enough time. As soon as I come home I can do them all. It's tragic and I've always liked maths. Now I'll carry this around with me for the rest of my life!

 

[mojako]

wot did u st00ges get for the locus?????

line y=-4a
x-coord is given by x=a(p-4/p)

as far as I know.. no restriction except that it's not defined when one of P and Q (or both of them) is at (0,0) on the parabola.

EDIT:
Oh SHIT !!!
when P or Q is at (0,0),
R is on x-axis!!!
I hope they don't mark me down...................................

EDIT #2:
Yes... good news..
Neither P nor Q can be at (0,0) if the two tangents are to be perpendicular

 

[Melody]

wrote the wrong question in wrong booklet, spent like 5min re writing it bahhhhh

Me too
Paper was waay too long, even if I had been 100% confident in my answers there's no way i could finsih all of it with my slow writing

Guesstimate: Late 50's, 60/84 (In which case it would be the first 3U test I have ever passed :uhhuh: )

 

[euphoric]

question 7a had too much english.
it should be a math exam. not a friggen comprehension><

 

[greekt0y]

yeh i got the answer y=-4a, it cant be y=0, it asks for locus, not the pont when its on the x axis
