Cheers for the insight.

The quicker method, surely you're referring to the substitution method?
It's the "mental method" - a hybrid of the substitution and equating the coefficients (when necessary)

Say you have

Sub in x=2 to . Get this number and write it on top of x-2

Sub x=-4 to , write on top of x+4

So in partial fractions:



If the question contains repeated linear factors, like this:

Sub in x=2 to . Get this number and write it on top of (x-2)2

Sub x=-4 to , write on top of x+4

Now for the number on top of (x-2) I equate the coefficients of x2



So in partial fractions:



i think he is reffering to the "supa cool method"

suppose:

5x = a(x-2) + b(x)
what you can do is,
let x = 0
thus you can solve for a straightaway
then for b
you let x = 2
which will make a = 0 and you can get b straightaway again.

if you call this substitution method, then you are not doing this method justice.
get it right and call it "supa cool method".
Sometimes I use this, but usually the above.


Looking at your subject marks, I reckon that as long as your English is up there, you may actually get 99.95. Infact, you remind me of Laurie Fields. :p
funny that you mentioned that, I thought the exact same thing

its a pretty cool way, but if you were to think about it, you are just using the "supa cool method" but just skipping a whole lot of working out lines. which makes your method quicker.

i shall give you a few names to name your method, you obviously have the honour of choosing them;

supa cool method 2.0
supa cool method 2
supa lynch method
method of death
supa fast method
awesomeness
VERY NICE
and finally my favourite
partial fraction in 10 seconds.

(y)

EDIT: i see you already have given a name. :-(

Well as you already know, Hugh Parsonage got 87/120 which equated to 93 HSC marks. Hopefully that gives you an idea.

Anyway, back on topic - 2004: 92/120
Oh ok. Seems reliable then. btw, got 108/120 for SGS 06, lost most of my marks on Q2 and the circle geo :(

Did anybody else find the 05 paper fairly difficult?

I managed 81/120. :(

2006: 93/120

Marked it very strictly, however being easy on the errors my mark would have been 99/120.

Just did HSC 1999 and got 114/120 but i found the probability to be hard and the last part of the circle geo.

i did 2006 last night and got 71%-would that be E4 orE3
Definately an E4. Anything over 70% is an E4. I'm pretty sure the person who sets the band cut-offs each yr for 4u sets them quite low (usually in the 60%s). I think last yr's paper was fairly difficult though, cause I know a few guys who got E4s and they reckoned they got 71-75/120. But anyway, yes, 71% would be an E4.
