T=P, theta=phi (they were the angles right?) but from angle on circumference phi remains that constant while theta decreases as x increases (shown from its eqn) so theta is less than or equal to phi, and max when theta =phi

Question 1-5 was similar to previous years, easy, the first half of Q6 and 7 were simple.
Omg the binomials was a piece of SHIT, DIE DIE DIE!
and lol i couldnt get the circle part of Q 7 oh wellz...expecting about 72 minimum atm

I got 1 + square root of something

sqrt(h(a + h))??? i just did it and got the same answer

 

[bored of sc]

Questions 1-3 were great (silly errors aside, 100%).
The graph in question 4 annoyed the hell out of me. Near 7/12.
With question 5 it was okay 8/12.
Question 6 was horrible i.e. 3/12.
Question 7 was more horrible i.e. 2/12.

56/84 give or take a few.

I hated that exam. All that study has seriously gone to waste.

 

[PunjabiBradPitt]

easy ....could have done another paper

Yeah, that's it, looks familiar.

I got so tired of writing all of it I ended up naming it "alpha"

 

[hayner]

hmm...wasn't expecting that...personally, i thought it was much, much harder than all previous papers...argh!!

niceee,
with the first part of 7ci
i just showed that angle PSR = phi - theta and then said that since its an angle its >0 therefore phi>theta, is that valid?

 

[annikab]

Yeah, I'm feeling pretty defeated. I tried so hard but I'll probably end up in the 50's. Bye bye E4

agreed!! i didn't really struggle during the trials or any other paper this year but that was....sad...

tan60 = o/h
o = h * sqr.rt(3)

Area of total triangle = 2 * (0.5 oh)
= oh
= h^2 * sqr.rt(3)

Volume = 10h^2 * sqr.rt(3)

---

I think that was the answer.

That's the answer I got too. But for 5(b)(iii) with the dh/dt i used
[1/(dv/dh)] * (dv/dt) and I only had -k left over.

Could anyone please explain it?

yeah I think so

I ended up writing an essay for that question

lol,
with that combinations q6, i had diagrams, colour codes, captions, the whole lot! only worth 1 mark spent about 5 mins, could have used it more wisely

that was my answer aswell XD wasnt sure if we were suppposed to get a numerical value, got to this q with exactly 1 hr left =S

lol, I answered those with essays too :mad1:

nah i reckon 2006 paper was hardest

 

[MONKEYjulz]

What was your answer for the number of days taken to get from 2m to 1m for the volume?

 

[study-freak]

I got 200 days after integrating and subbing in values. I hope that's right. It's 1 mark, so I think there was a simpler way.

Wasn't the answer 100 days?

 

[supamatt3112]

Generally thought it was very easy, bar question 7(c). Should get 70-75/84 from what i can tell looking back over it.

 

[Top Secret]

ROFL +1

I never would've thought I'd be writing essays in a maths exam!
