getting a straight flush?

so even if you buy a brand new copy of the Coroneos, it still has that really ancient font and the really cramped lay-out? i guess its kinda good if you're after light-weighted books with lotsa questions.

he substituted y=x^2/4a into the equation of the line. then he used the fact that, if the there is only one intersection between a parabola and a line, i.e. a tangeant, then the discriminant = 0. (this applies for not just parabolas, but all 2nd-degree curves, i.e. conics and probably various...

since the parabola has its vertex on the origin, it is in the form x² = 4ay ---- (I) differentiating, 2x = 4ay' x = 2ay' y' = x/2a now that line, x-y+3=0 y=x+3 ------------- (II) i.e. y' at the point of contact is 1. let the point of contact be P (x1, y1) at P(x1,y1), y' = 1 therefore...

don't you need at least 4 subjects?

this is really old, but i think getting a medal needs even more than 25/30. i got 27/30 last yr (2005) when i was in year 10, and it was still only prize.

haha La Campanella.. with a lot of dedication a normal person can hope to play it at an okay standard after probably 10 years. i mean.. learning the piece itself would take one year not to mention all the other years building the technique and maturity needed for such a massive thing.

aaah it's now $10000 for both usyd and unsw

100 or 99.95 is automatic $5000 a year. at least that was the case a few years back (i'm thinking 2003, 2004)

why are those "THE" 6 subsystems? surely there are more.. like pragmatics and register.

wtf?! i didn't do the paper but how come so many harder 3u topics??? like.. complex numbers and conics together had 1 and 2/3 questions. looks like the future of 4u lies in harder 3u...

i reckon the music dictation was pretty okay. like the pitch wasn't very hard (just minor triad and diminished chords), but since it was fairly fast it tooks quite a few playings.
