Oh my god, we have so much in common!!

if you want a band 6 in an english subject, keep advanced.

2. 1) tan4a = tan(2a+2a) = (2tan2a) / (1-tan²2a) [using the double angle formula expansion] = [2(2tana/1-tan²a)] / (1-tan²2a) [using the double angle formula expansion on the numerator) = [2(2tana/1-tan²a)] / (1-{2tana/1-tan²a}²) [using the double angle formula expansion on the...

1. let the roots be (a-1), a, (a+1) sum of roots: -b/a therefore, (a-1)+a+(a+1) = -p 3a=-p a=-p/3 when a=-p/3, (-p/3)^3 + p(-p/3)^2 + q (-p/3) + r = 0 algebraic manipulation of the above ^ gets 2p^3+27r-9pq=0

great job (and rank)!!!

yeah, this one i kinda did with my friend at our free period. lol wanted to ease his fears about the HSC

Yeah, economics is so much fun, i just can't stop laughing at times where i'm not sleeping in class, and anything is better than business studies, including, thats right, cambodian extension.

I like people who likes business studies. Hope that answers your question.

I totally agree, i'm only getting around 95%, feel like dropping it
