what do u guys wrecken the hardest yr's for 4u are so i can practice some. I havent done much and have less than ... days.

 

[Fosweb]

Theres a list floating around here somewhere (in another thread), if i remember rightly, 1993 was the hardest on the list, and 1989 was hard also.

1992 and 2000 were harder ones too.

lol... I lost 7 marks in the Ext1 trials question 5(didnt do the question ) and it ended up even lower than my ext2

 

[Constip8edSkunk]

in my trials my ext1 raw % was lower than my 4U raw %.... and ALOT lower when scaled, and im not the only 1 in my school lol

did '98 today lost another 3 marks in q1... completely missed a q....aahhhgggrrrrr

if i repeat my performances im so screwed for the HSC.....

 

[turtle_2468]

3U is always a tough one... check, check again...

 

[hk31]

i thought 1996 was hard...

 

[AK Gumbi]

1989- last question is just about impossible (and im not exaggerating about that)
1993- damn hard. average mark was around 47/120
2000-hard.
rest- not too bad. 2001 heaps good (for me anywayz)

3 u is damn hard.. you get 17 mins or so per question.. by the way, turtle, how long did the 3U exam take you?

I really dont get this

q/a = p^3/(3pq-bq^2)

the bottom part is an integer cause p,q and b are(given)

they say q divides a cause p and q have no common factor (also given in data)

I DONT GET THIS????? why

to add to above - i thought the subject of this thread was a joke

it wasn't as easy as 1999

edit: i'm in an ext 2 forum?? wasn't the list of hardest papers for the 2umaths? that's when 93 was hard?? and 99 easy?

coz ap^3 = q(3pq-bq^2)

every factor of q is a factor of RHS hence a factor of LHS.
now, since gcd(p , q) = 1 so any factor of q cannot be factor of p
or p^3, therefore must be a factor of a.

therefore every factor of q is a factor of a

so q|a

...

thanx for the reply but
since gcd(p , q) = 1

WTF does that mean?

 

[Fosweb]

Greatest common divisor i think.

well lookin' at ya nick, he was assuming that u were a 1337.

 

[Mathematician]

...

I still dont get the last part

therefore every factor of q is a factor of a

if every factor of q is a factor of a ----> q=a right???
so q/a=1???

 

[ricenoodles]

which quesiton is this from Mathematician?

No, if every factor of q is a factor of a, then q divides a. For example, every factor of 6 is a factor of 12.

 

[Mathematician]

...

oh so a>q?????

I get it now

thanx all

 

[ND]

Not necessarily, every factor of 6 is a factor of -12. In general it means a=kq, where k is an integer.
