relatively okay. relatively harder than last year paper i think.

7! / 7^7.

but you are still getting a mark lower than your external, which is the mark you deserve. i.e. although you came first in external, because of your internal rank, you are getting lower than your external, hence your cohort has pull you down.

MX1: high 70s-84/84 <--- but only once or twice. MX2: high 90s-mid 100s/120

yes. unfortunately that's how it is.

yes, if you aren't first in all your subjects.

they won't pull you up unless you are doing the same subject as them. otherwise, their atar will have no effect to yours.

let k = the constant of dx/dt dy/dt = (12xk)/ (1+(3x^2+5)^2) if x-> infinity, dy/dt -> 0

x-3ln |x+1| +c

centre (10,5) ? radius root 20 therefore (x-10)^2 + (y-5)=20 ?

i (9,3) e (14,7)

assume that we all know what is the quadratic formula. tan(\alpha -\beta )=\frac{ tan\alpha - tan\beta }{1+tan\alpha tan\beta } \\\\=\frac{\frac{\sqrt{b^2-4ac}}{a}}{1-\frac{b^2-4ac-b^2}{4a^2}}\\\\=\frac{\sqrt{b^2-4ac}}{a+c} then square it.

\int \frac{dz}{\sqrt{(z+0.5)(0.5-z)}}\\\\=\int \frac{dz}{\sqrt{(0.25-z^2)}}\\\\=sin^{-1}2z + c\\\\=sin^{-1}(2x-1) + c

easy one: - a stone is thrown horizontally with a velocity of 20ms-1 from the top of a tower 100m high. assuming no air resistance, and that the acceleration due to gravity, g = 10ms-2 find the velocity and direction of the stone on impact with the ground.

fail me. haha.

got everything except the minus 1. first you expand the binomial. integrate. let x = 7

to be honest i dont really know. maybe 1 band 6 and the rest band 5 ?

80+

module A - okay. easily adaptable. module B - a bit tricky on how they word the question and there isn't a clear link with community. so it's sort of hard in a sense. listening - the year thought it was hard. I thought it was okay. but it was heaps harder than our trials.
