Practice for Q7-8 (1 Viewer)

[irvine]

Okay, so- occasionally when I attempt a past paper, I can almost get full marks in the first 5-6 questions, but when I get to the Q7/Q8 (Harder 3U) I don't even have a clue where to start. It's not that I find the questions difficult to do, I simply don't have a clue.

Aside from simple practice, what are some other ways to improve proficiency in these open-ended/undergraduate math questions?

Thankyou

For question 7, you should be aiming to get about 60%. For question 8, just aim to get about 50%.

Question 7 is usually slightly harder applications of some randie 4u topic.

Question 8 is usually some rape ambiguous question.

For Q7, I just practise the harder questions which involve the use of things people tend to forget (like simpsons rule or cosine rule)

For Q8, I just persevere and write any shit I can deduce, then hope to grab some marks. I don't think many people can get the whole Q8 done.

I think I get about a total of 3 marks in Q8. It's near on impossible.

Wow you guys start past papers already? Does that mean you finished everything? i think im gonna start but im still missing out some topics =S

lol most schools should have finished the MX2 course by like half way through this term

No way. Most selective schools haven't finished the Ext2 course yet. Few schools ever finish the entire course before Term 3. At this stage, most schools should be up to Mechanics.

The best way to succeed in these questions is to perservere. There will obviously be questions which have really complicated answers that few people ever come up with, but most of them are actually quite simple if you sit there and have a good long hard think about it.

Our class still has volumes and mechanics to go, the other class in my grade just mechanics. That said, we've done all of the harder extension one which I know some schools haven't done...

in case someone's not too familiar with the terms:
semiperimeter --> 1/2 the perimeter
inradius ---> the radius of the circle with the 2 edges as tangents
circumradius --> radius of the circle passing through the 3 corners
heights -> perpendicular distance from a corner to the opposite edge

schools should be up to harder 3u now, but most people should've tried the 2001-2009 papers for the heck of it. i just death stare at the question 8 :x

For question 5, so far i can only prove

.

But im having difficulty in showing that,



Infact, i think it could be the opposite. ): Buchanan, any hints on how to show it?
Also, where do these questions come from?

just wondering but does anyone else here actually have difficulty with majority of the Qs in the CSSA trial papers? I'm about to kill myself..........

doesn't work.

i try that as well

It works if:

It works if:

But that is almost never true given that all but at most 1 of the a's need to be less than 1.

Need to be less generous with the other part to prove the whole inequality.

CSSA papers are getting easier over recent years. Don't stress.

Do more practice and you should be fine.

CSSA isnt that bad. are they meant to be easy? cause.. =/ .. ye....
2009 was pretty easy
2008 was hard =[
i dont rate exams accordin to Q1-6
Q7-8 tell u how hard an exam is imo...
for eg..2009 was easy....induction easy, inequalites...back track...reduction formulae easy....and circlue geoo :| easy..
2008 on the other hand...god...binomial theorem in generating inequalities....finding the limits of the fib. sequence...
Q8 (c) though was easy..just testing how well you know the fundamental theorem of calculus..and how it came to be

ok i sound like a fuckwit ^^^
4unit is fucking hard, just keep doing past papers guys, you'll get through
