would do e errational thing come out dis hsc???? (1 Viewer)

[jpk]

would it come out.....or not ..watz probablity?

 

[ND]

Even if it does, there's nothing you can do to prepare for it.

They'll just come up with a different method of proofing, and guide you step by step for marks. Proof it using other methods, and you'll lose marks.

I dare bet it wouldn't be irrationality of e..

some of the stock questions:

Geometry:

ptolemy's theorem
Butterfly theorem
Simpsons theorem(this was in last years)

Inequalities:

QM-AM-GM-HM
Cauchy schwarz

Other Harder 3U:

fibonnaci sequence/other reccurence sequences
the tower of hanoi problem
divisibilty

 

[Saul]

there's no way they'd have the e irrational one again any time soon... its too unique.

 

[underthesun]

Cauchy schwarz.. didn't Terry Lee confuse it with AM-GM in his book? So, what's the cauchy schwarz then?

so where do i find details on how to do them?

Haha i was waiting for that.

 

[underthesun]

There's always google, mathworld, or even everything2.com

but with only 2 days left til HSC, it seems worthless...

oh ND, your postcount is catching up to mine . At least ours is not from non-school forums

 

[ND]

Heheh yeh, all the non-schoolers got screwed over when it was changed so that they didn't count.

ok, so i understand about 5 words in that list, including theorem...and divisibilty

 

[Affinity]

simpson's theorem was question 4b last year

ptolemy's theorem states that for a cyclic qud ABCD

AB*CD + BC*AD = AC*BD

most of those questions are in arnold's book

 

[deyveed]

How do you people know of all these theorems?
I don't think they're in the textbook so why do we have to know these formulas?

 

[Affinity]

you don't. I was trying to say that there's no point in remembering theorems.. they will lead you through the proof.
they are in the textbooks though

yeah, but its good to b familiar with it though.

 

[Rahul]

as practice, but not for remebering the exact proof and hoping it comes up in the exam.

yeah, i can't belive that i'm in the top 30 now.

affinity: repeats the above to classmates

classmates: what's the point, we're not going to use it after the HSC
