[DRAGONZ]

Thanks a bunch ...

Now to find out just how pwned I got :-S

 

[Sepulchres]

Yea a few silly mistakes. Dammit.

 

[renya]

lol, i did the test yesterday and i dont remember any of my answers.

im convinced i got question 1a wrong

 

[Sonjay-]

yeah it's good to know what mistakes u have got

it's all about getting soemthing over and done with

 

[Abtari]

there are a few mistakes with terry lee's solns that i found...

like the graph question, the part between -3 and 3 shouldn't cut the asymptote y=x

and in the complex no. question, the extremities of the diameter of the circle, at (1,1) and (1, -1) should be excluded with 'little circles'...

ah well

 

[EvilDude]

I'm impressed he has soolutions up already.

Made me find some stupid mistakes, yet at the same time confirm some things..

(Eg getting the probability right, that was good )

 

[Boz_87]

Can someone plz email me the solutions at bosz_man@hotmail.com coz the site aint working for me thanks.

 

[vwola]

And me, i dont wanna look at them. It might wreck my enjoyment between the end of the HSC and the time we get our results back. ie. i probably failed but i dont wanna see that its certain i did.

eeekk
90 for me...

 

[~ ReNcH ~]

I can't see the solutions on the page...can someone post them up?

Btw. do you lose marks for transcription errors in the HSC? For thw partial fractions, I accidentally wrote "3x" instead of "5x" and so of course I got "a" and "b" wrong as well as (ii)...

 

[Jeeeb]

Yeah I'm happy now, I'm pretty sure my mark is between 82/120 and 77/120 now maybe take a few for silly mistakes i don't rember making . Cheers to Terry Lee for the sollutions.

 

[desperate cat]

nope you dont unless you made the question significantly easier in which case you didnt

Ok, that's cool
I was kind of wondering why I ended up with fractions for a and b, but I didn't go back and check until I came home and realised.

 

[chinesefireball]

like the graph question, the part between -3 and 3 shouldn't cut the asymptote y=x

yes it does.

y = x + (8x)/(x^2 - 9)

sub in x = 0, no problem. curves can cut the asymptote - it only tends towards the asympotote when x tends towards infinity

 

[~ ReNcH ~]

Is Terry Lee's region for Q2(c) correct? I forgot to make y=1 a dotted line...I wonder if I'll be penalised.

 

[..:''ooo]

eeekk
90 for me...

wtf??? wingers like u make me wanna vomit

 

[Estel]

Rench: you'll be penalised. Also note there should be open circles where the line cuts the circle.

Lee's graph of the curve is also incorrect. The curve cuts the asymptote y=x only once, at (0,0), as opposed to thrice as his diagram suggests.

wtf??? wingers like u make me wanna vomit

Whingers like you would make me want to vomit if I cared enough.
