Let me put it in this way: the mark your school submits to the board of studies is used as a reference for assigning your "assessment marks"

There's always the physics mistress (oops :D)

try this: T(1) + T(2) + ... + T(n) +T(2) + T(3) + ... + T(n+1) = T(3) + T(4) + ... + T(n+2) (since T(1) + T(2) = T(3), T(2) + T(3) = T(4) etc.) therefore T(1) + T(2) + ... + T(n) = T(n+2) - T(2) = T(n+2) - 2

You can find things by inspection

or you can do: sin(3x) - sin(2x) = 0 sin(2.5x + 0.5x) - sin( 2.5x - 0.5x) = 0 simplifies to: 2cos(2.5x)sin(0.5x) = 0 and you can work the rest out I hope

me? I am at UNSW .. and the quote in my signature is from someone else's conversation

no.. it's next to the best subject .. extension 2

many elementary functions don't have elementary functions as integrals

some webpage which does integrals for you.. try integrals.wolfram.com

modulus is 8 argument is -2Pi/3 so one of the complex sixth root is sqrt(2)*cis(-pi/9) the others can be found by adding Pi/3 to the argument

I think ..<I agree with archman> <-- fake html tag</I> anyway, extension question find the probability such that the number of sixes rowed is a multiple of 6

85+ if I remembered correctly.. Forget about Bands.. they mean nothing for UAC

doing it alone is good... you don't have to care about assessment tasks.. I think there's some room for improvement

^^ yes 1, you eliminate the y's from the equations substituting the second equation into the first. so x(x^2 - 5x + 6) = 5 2.) 3^2004 = 9^1002 = 81^501 and you can see the last digit is 1 in the expansion, so the remainder is 1. (81*81 = xxx1 then you multiply by 81 again, but...

maybe post the answers as attachments?

actually it's building a mental picture of the separate pieces.. and this applies to other subjects as well.

1.) you know how to use it.. 2.) Hmm.. weird.. coz it should deflect. learn it.. would be useful in third module, and you don't have to exclude something just because it's not in the syllabus

harder

perpendicular to the line

same drill, slice the thing up, and find the volume of each slice.. and integrate.. I guess that's like treating the line y=x as the.. say u axis
